食品事故の問題は発生場所だけに収まらない  

Gabe Miller (00:00):
So they would sanitize the room, they would sanitize the equipment, they would sanitize the floors. And the first thing the operators did was to come in the room, and as they opened the door sweep, it would contaminate the floor, people would walk through it. And over the course of the day, that contamination, just through movement in the room, Would get up onto product contact surfaces. Back then, if there was a food contamination, it was very contained. They shipped product to Chicago, which was a big market, And if there was a contamination, it affected a small population. Now we ship products around the world, and so if somebody has a foodborne contamination, it can affect everybody.

Mikkel Svold (00:44):
There are two big things in the 3As. If the product touches the surface, it must be a product contact surface, and if it doesn't touch the surface, it must be a non-contact surface. I know I'm wrong, but why am I wrong?

(01:11):
Food manufacturers and machine builders, they face a constant balancing act trying to deliver safe, high-quality products, while also, of course, navigating some of all of these standards on hygienic design that we have. Misjudging a surface or overlooking a slight detail in the design can lead to contamination, and of course, costly recalls, and damaging reputation. We've talked about and covered this in plenty episodes before this one, including the one with Bill Mahler on the legal side of contaminations. With the recent updates to the 3A standards, I think it makes really good sense to take a look at the requirements for hygienic food production again to revisit what's happened. And today that's what we are going to talk about in Behind Clean Lines.

(02:04):
I'm Mikkel Svold, and with me I have Gabe Miller, who is a 3A CCE. That is a certified conformative evaluator. That means that Gabe has spent his career inspecting equipment to certify it against the standards. And I would probably argue, has seen firsthand what these changes, they can actually do to a food production. Welcome to you, Gabe.

Gabe Miller (02:31):
Hi. Thanks, Mikkel. I appreciate you inviting me.

Mikkel Svold (02:34):
Joining us as well is Tue Skrubbeltrang from NGI. You're the commercial director at NGI. And what you're participating with is basically the insights from the food producers and the OEMs producing the machines. So I hope you have some of the hands-on knowledge on to implement some of these standards. Welcome to you, Tue, and am I right?

Tue Skrubbeltrang (03:00):
Thank you very much, Mikkel. I sure hope that you're right because we have approximately 5,000 customers around the world, mainly OEMs, with whom we regularly speak. So we get a lot of direct feedback from the companies actually manufacturing the production equipment for the food industry.

Mikkel Svold (03:22):
Perfect. Perfect. I think, let's just try and dive right into it, Gabe. Maybe you can take us through the 3A standards. They've just been updated. What has happened?

Gabe Miller (03:35):
Okay. So for anybody that's not familiar, I'm going to just give a really brief background. The 3A standards have been in place now for almost 100 years, and they were developed because of food contaminations. The officials in the city of Chicago about 100 years ago, were recognizing that children were getting sick and dying from foodborne contaminations. And so they developed these standards, and the standards have evolved over the years. Back then, everything was taken apart to be manually cleaned. They made pipelines out of glass. They didn't use the same materials that we have available today. So the standards have constantly been being revised to keep up with current technology, current practices, manufacturing methods, new ideas for making things. And of course, the scale of manufacturing and the automation that's going on now is completely different than it was 100 years ago, as everybody can imagine. Everything then was very manual and now everything is very automated.

(04:41):
And also back then, if there was a food contamination, it was very contained. They shipped product to Chicago, which was a big market, and if there was a contamination, it affected a small population. Now we ship products around the world. And so if somebody has a foodborne contamination, it can affect everybody, both commercially, and of course, from a health standpoint. If anybody has followed any of the recalls that have occurred, both in Europe and the US and other countries, when there is an issue, it is very widespread because we manufacture products and send them everywhere. So the whole climate has changed in the food manufacturing process and the standards have continued to evolve to keep up with that.

(05:35):
So the general standards, this is now the third iteration of them. When the general standards were first developed, I happened to be the chair of the committee that developed them, and we had input. The 3A standards are developed by input from three groups. Why it's called 3A is three agencies, the regulatory bodies, which are the FDA and USDA inspectors, the equipment manufacturers, who are NGI and all the companies that manufacture the valves and the fittings in the tanks, and then the processors, the people who actually use the equipment. Those three groups of people now develop the standards in a collaboration, and all three parties have to agree to the standards in order for them to be adopted. So nobody is the gorilla in the room that can impose anything or create criteria that are not practical for the other groups.

Mikkel Svold (06:40):
Can you come up with an example where that has been the case?

Gabe Miller (06:44):
Well, I'm going to say radii. People who are manufacturing equipment don't want to be constricted very much in the radius in the corners, because sometimes from a manufacturing standpoint, it's easier for them to make something that has a sharp corner. If you're welding two components together in an angle, at a 90 degree angle, if it's a sharp angle, it is very difficult to clean. The larger the radius, makes it easier to clean. And so the regulatory body want it to be as large a radius as possible. Equipment manufacturers don't want to be constrained by that. And so we had to reach an agreement with all parties. And the end users, they don't care as long as it's cleanable and it doesn't cost too much and it meets the regulatory requirements. So everybody has a different perspective, but radius is a issue that we reach a compromise between all the parties about something that is practical to manufacture, but also cleanable and inspectable.

Mikkel Svold (07:59):
I want to turn to you, Tue, because when I look at the NGI product portfolio, I've never thought about it like this, but it has an organic look to it. It looks like it has organic shapes, but I guess this is the reason that Gabe Miller just gave, is you need the rounder edges.

Tue Skrubbeltrang (08:25):
Yeah, this is-

Gabe Miller (08:26):
We don't get marketing involved in designing things. It's from a standard standpoint, but it does ... I never thought about that, but you're correct, everything tends to be rounded.

Mikkel Svold (08:39):
Yeah, Tue, what thoughts go into that process at NGI?

Tue Skrubbeltrang (08:42):
This is basically a hygienic feature. It's not really a design choice for the optics. It looks nice and it looks organic, as you say, Mikkel-

Mikkel Svold (08:53):
Yeah, it does.

Tue Skrubbeltrang (08:53):
... but it's really to achieve the best cleanability. The rounded corners make it easier for the surfaces to be self-draining. So that's basically why we do that. And these design criteria, which are defined by, among others, 3A, EHEDG, for instance, are very well-known to us at NGI. Our entire design department know these in detail. And every time we design something, we of course commit ourselves to these design criteria to make sure we are always as hygienic as possible.

Mikkel Svold (09:30):
But is it harder to manufacture?

Tue Skrubbeltrang (09:35):
In some cases, it is, but not necessarily. And this is actually a really important point. We try to also spread this message to many of our customers, the OEMs, because it is a well-known myth that hygienic equipment is more expensive to make than generic equipment. And this is not necessarily the truth. To some extent it might be, but in many cases, if you design correctly from the beginning, it doesn't have to be more expensive to make, at least not necessarily. And that same goes for us. So if we do it correctly from the start, we can actually make something hygienic without it being too expensive.

Mikkel Svold (10:18):
I think it's also been very clear from earlier episodes talking to all kinds of people, exactly what you say. If you know it from the very beginning of a design process, it's not necessarily adding any cost. But on the flip side, if you try to retrofit hygienic design or try to retrofit components, it seems from earlier episodes at least, that that can be really costly. But anyway, I want to actually come back to the development in the 3A standards, because just three weeks ago there was an update. If you were to break that down, Gabe, just in easy chunks, what did that update do, the one that's very new?

Gabe Miller (11:06):
Okay, so the update has not imposed any new significant criteria to the standards, but it has clarified some of those criteria. The welds on surface finishes, the previous standard had an ambiguity the way that it was written, that two different people might interpret the criteria for surface finish on a weld in two different ways. And it became an issue a few times when a regulatory person said, "That doesn't meet the standards," and other people looked at it and said, "Well, it certainly does," because they're looking at different language in the same clause of the standard. So that was clarified to make sure to eliminate, hopefully, any ambiguity or misinterpretation of that particular clause. The radius in the corners of some seal joints, we have some very specific criteria around the different types of O-rings versus mechanical force seals and the radius that's required in the corners. And so we tried to clarify that language to make sure, again, that it was not misinterpreted. When somebody looked at it, they say, "Oh, that's not compliant with the standard," and somebody else says, "No, it is." So we tried to clarify that.

(12:31):
The other thing that we have added to the standard is a lot more materials that had not previously been listed specifically, especially around stainless steel or metal materials in the standard. We now have a whole host of tables of other type of materials, the general criteria for standards is everything has to be at least as corrosion resistant as 304 stainless. It's been around for 100 years. But there are many, many different applications that require different materials with greater corrosion resistant. Nowadays, most equipment and product contact is manufactured from 316L stainless steel. It's a more corrosion-resistant material, but 304 is still the basic reference.

(13:21):
But there are also many applications where people need a material that is either higher corrosion resistance because of the environment of its use, or a harder material because it's like a piston on a filling machine, where 304 or 316 might not be suitable for a moving component. They also have other materials for different applications. And so the standard has expanded all of those tables to be able for a manufacturer to reference and find alternate materials that may suit their application, without going through a lot of testing to decide if this is okay to use.

Mikkel Svold (14:04):
You know what? If I were an OEM machine builder, every time I heard that the standards were about to be updated, I would be a little bit nervous, because you never know if you suddenly have to change something in your production. Is that something you meet?

Gabe Miller (14:30):
That's a really good point, because regulations always seem to become ... They evolve to become more stringent over time. And we attempted to make sure we did not do that unless there was some compelling health reason. If somebody were to say, "You know what? I think a smoother surface would be better than the 32 micro inch or 0.8 micron, it would be easier to clean. It would be more sanitary," okay, well, that might be true, but there is no public health reason to try to change that particular criteria in the standard. So it has remained the same. We tried not to impose any new criteria in the general standard that would disenfranchise or require significant changes to current symbol holders.

Mikkel Svold (15:23):
And Tue, Skrubbeltrang, at NGI and your partners, is that the same experience?

Tue Skrubbeltrang (15:32):
I'd say, to be honest, that unfortunately when the design criteria, for instance, from 3A are updated, I think that unfortunately, many of our customers, the OEMs, do not necessarily know about it. So this is, of course, something that Gabe and his colleagues work hard to change and promote the fact that there are now updated or revised criteria. But I think in many cases, unfortunately, our customers are not necessarily that aware and they might not see it until a customer specifically points it out to them that they need to comply in a different way than they've been doing so far. But I definitely agree, Gabe, in the way you guys do it, that you don't make changes just to be able to offer something new or improvements for the sake of improvement if there isn't really a proper problem. I think that's also the way to make sure the OEMs actually take notice when you have something relevant new to offer.

Mikkel Svold (16:43):
Yeah.

Gabe Miller (16:43):
Yeah. So one other thing that has happened in the standards, we've also looked at newer technologies. Things have evolved. And so a few examples are for metal fabrication. Before, everything was made out of either cast material or solid material and machined. And now, of course, we have injection molding of metals, we have 3D printing of materials. And so we try to also allow for manufacturers to adopt some of the newer technologies as long as they met the fundamental criteria in the standards. It's got to be inspectable, it's got to be cleanable. It can't be porous. It can't be like a sponge that water can get into it, because that would leave openings for bacteria to contaminate surfaces. So we have added some language in there to allow for some of these newer technologies to be used, not creating an additional criteria for people, but providing them with a means of manufacturing equipment that might be better or less expensive or provide a better surface finish for something. And so that's also in the newest revision of the general standard.

Tue Skrubbeltrang (17:53):
Okay.

Mikkel Svold (17:58):
I want to shift the conversation a little bit now, because we've talked about all the different standards, but you've also mentioned surfaces quite a few times. And what we talked about before turning on the microphones last time we spoke, there are two big things in the 3A. There's the product contact surfaces and there are non-product contact surfaces. And it seems to me such an easy thing to understand. If the product touches the surface, it must be a product contact surface, and if it doesn't touch the surface, it must be a non-contact surface. I know I'm wrong because we spoke about this before, but why am I wrong?

Gabe Miller (18:43):
That is a really good question, and one of the things that we are constantly trying to educate people. And to refer to it before, that the OEMs, equipment manufacturers or end users may not be familiar with the concept of what might be considered a product contact surface. So you're correct, obviously, anything that comes in direct product contact is a product contact surface. That's a duh. Okay.

Mikkel Svold (19:13):
Yeah. Good, good job.

Gabe Miller (19:14):
But the other definition in the 3A standards is that it's components, surfaces that are in contact with the product, or any surfaces from which liquids can drip, drain, or be drawn into product contact or in contact with the product contact surfaces of the packaging.

Mikkel Svold (19:42):
Wow. I think we need to break that up just a little bit because it sounds like a word puzzle.

Gabe Miller (19:48):
Okay. So some of it is very simple. Anything that can drip into the product is a product contact surface. If you think about a pipeline or even a ceiling over the top of product, if it's got condensation on it that could drip into the container or onto the product, becomes a product contact surface unless it's shielded to prevent it from dripping into it. And we run into this primarily on filling machines all the time, because the containers are coming down the line. They're on a conveyor belt. They have to go underneath the filling head. And so the pipeline that's carrying the ... Let's think yogurt, we're filling yogurt. The pipelines are very obvious. We can make them sanitary, but as that container is coming underneath the filling nozzle, any liquids on the filling head, which are going to be condensing because it's cold product, it will condense water. And I've actually watched a filling machine where liquids were dripping off the top of the filling machine into the containers.

(21:04):
And so all those areas are considered product contact unless there is a shield put in place to make sure ... Think of an umbrella to keep water off of you. It's not much different. You're trying to keep anything from above from dripping into the containers or onto the product.

Mikkel Svold (21:27):
That also makes quite good sense, and it's not directly understandable, but it's still easy to acknowledge that, yes, of course this must also be clean. It must also be very hygienic, obviously.

Gabe Miller (21:45):
Yeah. So once it's-

Mikkel Svold (21:47):
What are some of the edge cases?

Gabe Miller (21:49):
Well, the other things are a conveyor belt. Let's just think about cheese that's on a conveyor belt. Of course, the conveyor belt surface is a product contact surface because the cheese is sitting on it. But the conveyor belt also rolls around underneath itself. That's the way conveyor belts work. So anything that is a contaminant that's underneath or inside the conveyor is now going to drip onto the belt, and now the belt is going to roll around and the cheese is going to sit on it. So everything that's inside that conveyor, the rollers, the bottom of the conveyor, all become product contact surfaces because of the conveyor belt coming around to contact the product. So that is a real good edge situation that people are not aware of. And I've got some fantastic photos to show you how really badly things can go wrong when people are not paying attention to that issue. They don't think about it. And so that's probably the biggest edge situation that you have.

Mikkel Svold (23:06):
I know, Tue, that parts of NGI's product portfolios is the bearings. Can you try and put some words on how you've been thinking about this exact issue?

Tue Skrubbeltrang (23:19):
Yeah. Well, our bearings are probably a good example because in many cases, they are not actually meant to be placed directly in the product contact surface, but they are placed right next to the product contact surface. And when you transport food products, for instance, you cannot always 100% control where the product is. So on a conveyor, for instance, if you transport raw meats or something like that, they might flap around a little bit. It sounds disgusting, but that's how it is in real life, flapping meat. And this meat might actually come into contact with our bearings.

(24:04):
But even more importantly, bearings are a dynamic part. It turns continuously during the day and it has to be lubricated in order to work properly. And most bearings are lubricated many times a month to make sure that they are properly lubricated. And this lubrication has a tendency to leak from the bearing, and this is lubrication which might also spread to the product, for instance. It's really hard to control how that spreads and where it spreads to. Even though the bearing is outside of the product area directly, it might still be that this lubrication can spread to the product.

Gabe Miller (24:55):
That is a really good example. In the standards, I'm actually not sure about the EHEDG standard, how they handle that, but in the 3A standard, lubricated bearings have to be separated from product contact surfaces by a minimum of one inch or 25.4 millimeters that is visible. So that if there is any leakage in the bearing, they can see it before it reaches over. And one inch is probably an arbitrary number because it was an even number many years ago, but it's a reasonable distance to require separation from a lubricated bearing from a product contact surface for the very reason you just pointed out.

Mikkel Svold (25:37):
I know we talked about also an edge case in our prepping to this podcast. You talked about something, was it in a doorway or something like that? Can you maybe dig up that example again? That was very Interesting.

Gabe Miller (25:51):
Okay. So this is now why our non-product contact surface is important. The first thing that we talked about is, what are product contact surfaces? And so that's actually fairly well-defined if people understand it. But for equipment that is a non-product contact surface, people tend to regard it as much less important. It's not obviously not as critical as those components in direct product contact, however, non-product contact surfaces also become very important because they can harbor contamination that migrates into the product. Microbes aren't very mobile. They don't swim, they don't fly. Okay, they ride. They ride on us, they ride on our equipment.

(26:39):
And so the example that I told you about was in a meat processing plant that, for a period of a year had a continuous contamination in their product, or high microbial content on their product contact surfaces for listeria, obviously a very serious organism. And they could not find it. They did a tremendous job of taking the equipment apart. They had tabletop surfaces for handling meat that were stainless steel. Solid stainless steel. They cleaned it, they sanitized it. In the morning, it was completely sanitary, and by the end of the day, it was contaminated. And ultimately, what they found out was that the doorways coming into the room were hollow at the bottom. They did not have a seal to the inside. And so they would sanitize the room, they would sanitize the equipment, they would sanitize the floors, and the first thing the operators did was to come in the room, and as they opened the door sweep, it would contaminate the floor, people would walk through it, and over the course of the day, that contamination just through movement in the room would get up onto product contact surfaces. So, those non-product-

Mikkel Svold (27:59):
Basically riding on other stuff. So riding on water droplets, riding on-

Gabe Miller (28:02):
Riding on other things. People's shoes, people's clothing. The wheels, if you're bringing a cart into a room, if you think about it, the cartwheel is rolling. What's happening? The floors are a little wet. As it rolls, it slings that up into the air. And where does it land? Onto product contact surfaces. So the non-product contact surfaces, while the criteria in the standard is much more relaxed, those surfaces still have to be cleanable and inspectable to minimize the risk of cross-contamination between those areas and the product contact surfaces.

Mikkel Svold (28:41):
I don't know if you were involved in it back then, but I just wonder, how do you discover, how do you come to the conclusion, "Oh, it must be the doorway." How do you discover that? Take the whole thing apart-

Gabe Miller (28:57):
I was not there when they were swabbing. So by the quality control people in the processor's plant, they would do swabbing of all the equipment before they started production in the morning, and they would also swab other surfaces. And I'm not sure how they happened to find it. I wasn't in the facility when they had that aha moment when they realized this was the source of it. But somebody in swabbing figured out that this was the root cause of the problem.

Mikkel Svold (29:31):
And then you replace the doors?

Gabe Miller (29:34):
And then you replace the doors.

Mikkel Svold (29:36):
Tue, you want to join in?

Gabe Miller (29:37):
Tue, you want to talk about your equipment?

Tue Skrubbeltrang (29:41):
I always want to talk about my equipment, but actually, not in this case. I was just going to add that probably this doorway was far away, probably many meters away from the product contact surface, but still it was a problem. And this just emphasizes why the equipment, in its whole should be hygienically designed to avoid having these issues which might lead to contamination. And I think this emphasizes the importance of a proper hygienic design and why should you follow the 3A guideline. It's because you want to have machinery with limited or even ... Yeah, you can never completely eliminate, but at least reduce to a minimum, the contamination risk. But also improve the cleanability of the equipment, because cleanability also means commercial advantage. The machinery is cleaned every day, in some cases several times a day. So you spend a lot of resources cleaning the machinery, and if the machinery is as hygienically designed as possible, it's also easy to clean and you can actually save money every day in the production.

Mikkel Svold (30:58):
Yeah, and I guess a good point here is also that production halts when it's cleaned, right?

Gabe Miller (31:04):
Yeah.

Mikkel Svold (31:04):
So the faster you can finish a cleaning cycle, the more production you can have running, or you can have it run more continuously.

Tue Skrubbeltrang (31:15):
That's a very good point. It reduces downtime also.

Gabe Miller (31:18):
If I can comment, one thing that Tue had said earlier, and also referencing the time for cleaning, people think purchasing managers don't get involved, unfortunately, in the sanitary design purchase. They think their job is to buy the cheapest equipment that they can get, very often. And what they fail to understand too often is, they pay for the equipment one time and they're going to live with it for 30 years. And so if they put in equipment that's not easy to clean or easy to inspect or not sanitary, it may be less expensive when they put it in, but over the course of its use, it could become extremely expensive for them either because it takes longer to clean or they have contamination issues that create these big problems.

Mikkel Svold (32:06):
Yeah, because one of my questions would be, why not just make everything super hygienic? It's like the entire factory, just make it one big clean room. Why is that not a thing?

Tue Skrubbeltrang (32:19):
This is where my experience comes into hand, I think.

Mikkel Svold (32:23):
Yeah, I think maybe.

Tue Skrubbeltrang (32:23):
I get this feedback all the time, but I'm sure you do too, Gabe. But of course, it's a matter of cost, like I said. There is a myth that it's much more expensive to make hygienically optimized equipment, which is not necessarily the truth. But it might be that some of the details do make the equipment a little bit more expensive to produce, and of course, for the food manufacturer also to buy. But this is a one-time investment. You do that once, but you produce on the machine probably for at least 10 years, maybe even 30, as you said, Gabe. And the headaches of a suboptimal hygienic design are every day.

Mikkel Svold (33:10):
I want to look a little bit into the future. What can we expect from the standards going forward? Do you expect the European standards, maybe even the UK standards ... I know that they, of course look alike. But the European standards and the US standards, the 3A standards, do you expect them to be more aligned in the future? Do you expect them to collaborate more?

Gabe Miller (33:43):
Okay, so we do have a collaboration, we call it harmonization, between EHEDG and 3A. I actually collaborate with EHEDG frequently. I do training for the EHEDG Central American conferences. I do training for them there. I know the people quite well. And in the 3A standards, we actually recognize some of the testing that's done at EHEDG as compliant with the 3A standards. When we talk about cleanability, CIPability of equipment, they have a Doc 2 is one of their standards, and they do really good testing for pumps and valves and fittings and components. And if equipment meets EHEDG Doc 2, I consider it to be CIPable. The seals are good. It's completely cleanable. They do an excellent job of that. So we harmonize with them in some cases. Some of our standards are actually parallel to each other. The surface finish is the same. The welding criteria. If you look at their welding standards to our welding standards, they're the same.

(35:04):
And there are some things that won't change because they take a slightly different approach to it. In 3A, we are prescriptive. We tell you, "You have to have a certain radius, you have to have a certain ..." Radius, I guess is a big one. We establish the criteria. If they meet those criteria, we consider it to be sanitary. In EHEDG, they depend on testing. They say, "Okay, so you built it to be sanitary, but we have to test it." And they are more not prescriptive, but proscriptive. I don't know. They test to verify it. And so again, we recognize it, but it doesn't apply to all equipment. It's good for small components, but if you're making a filling machine or building a silo where you can't fill it up with a gel material and do the testing on it like that, we have other methods that we recognize as meeting the standards to verify that it's cleanable.

Mikkel Svold (36:06):
But would it be fair to say that if you comply with either of the standards, you should be more or less home safe in getting the certification across the pond as well-

Gabe Miller (36:19):
Almost.

Mikkel Svold (36:20):
... on either sides?

Gabe Miller (36:24):
Almost. The only thing that becomes a little bit of a problem, there is materials. The European regulations regarding toxic materials or food grade materials are different than the US regulations, and I cannot tell you why. That's a regulatory issue. But the U.S. FDA regulations for accepting rubber or plastic materials are slightly different than those in Europe. Now, there are many manufacturers of rubber components that meet both. That's a perfect world. But in general, your statement is true. I tell end users, I said, "I don't care which equipment you buy. If you buy 3A or EHEDG certified equipment, it makes no difference to me. As long as the materials comply with your regulations, it's going to be sanitary."

Mikkel Svold (37:21):
I think just, our time is nearly up, but I want to ask you one last question, and I want to ask you first, Tue. On your wishlist for sanitary standards going forward, is there anything that comes to mind that you wish would change or would be added or would be subtracted or ... Yeah.

Tue Skrubbeltrang (37:54):
To be honest, I think that's out of my area of expertise to challenge what the experts recommend, if I'm being honest. But I think my prime wish for the future would be that everybody from the food industry, the OEMs and the brand owners were more knowledgeable about the design criteria, because this would help all processes extremely. Every time you design a new piece of equipment, if you do it right from the start it's much easier, and the end result will become much better. And it will support food safety and commercial advantages much better than the current standard does, at least.

Mikkel Svold (38:47):
And Gabe, what about you? What's on your wishlist?

Gabe Miller (38:51):
On my wishlist, actually, I'm going to echo what Tue just said, is knowledge, for people to become familiar. When they start designing equipment, if they start off with sanitary design requirements as their first requirement and design around it. As Tue said before, it's not necessarily any more expensive to make a corner when they're machining it, whether you use a zero radius or a quarter-inch radius tool. Sometimes it's easier to make something with a radius than it is to make it a sharp corner if they just knew what they should do. I've gone in and looked at inspecting equipment and people said, "Well, this is how we design it." I look at it and say, "You know, if you didn't do that, it would be less expensive for you to make it and it would meet the standard. You've done something that is now more difficult to clean and it doesn't meet the criteria."

(39:45):
So it goes back to knowledge for the people who are doing the design and for the people who are purchasing equipment, to be aware of the standards and understanding the need for sanitary design as a first criteria instead of an afterthought.

Mikkel Svold (40:05):
So summing up, the need for knowledge on the standards and what's going on with the standards. And also, I'm also hearing the need for maybe puncturing the myth of hygienic equipment being more expensive. I know that that is the case in some cases, but I'm also hearing you say that it's not necessarily more expensive. It's just the design-

Different.

Mikkel Svold (40:32):
... choice.

Gabe Miller (40:33):
It's different.

Mikkel Svold (40:34):
Yeah, it's just different. Gabe Miller-

Tue Skrubbeltrang (40:37):
Mikkel, because as we spoke about, it's only the machine that's more expensive probably to purchase, but over time, the total value of ownership will be much better because it's easier to clean, you reduce risk, and you reduce the cleaning time and the cleaning costs.

Mikkel Svold (40:59):
I think let's end on that. Gabe Miller, Tue Skrubbeltrang, thank you so much for joining the show today. If you have any questions for either Gabe or for Tue or for me, or for the rest of anyone that we've had on board this podcast throughout the episodes, do reach out to us on
