Maintaining your Equipment: Is it the Missing Ingredient in your Recipe for Food Safety?

Although I am no longer in day-to-day operations, between our students and foodservice lab at the university and my volunteer activities in my local church, I keep a close hand in food production. This past week, I had the opportunity to lead a group of men at our church in preparation of a luncheon for 100 women who were attending a spirituality retreat.  Over the course of the morning, I realized our main cooler in the kitchen was not functioning properly and was about 10˚F above the required temperature.  While we do have a commercial kitchen, we do not routinely log temperatures, so when the unit started to malfunction is questionable.  Even more concerning was not the lunch we were preparing for, but the dinner that was served the night before for 300+ families in the parish.

I am certain stories like this are commonplace in foodservice operations across the country.  I can think of several instances when I was in day-to-day operations that were similar. While we (and I especially through my research focus) tend to focus on employee behavior and developing the culture of food safety we have discussed several times before, including our last blog, the truth is that properly functioning equipment are really the backbone to our food safety plan.

It all starts with our food storage equipment – as soon as food arrives in our restaurant, many items are placed in refrigerated storage. While there are several issues that can arise with coolers that I would not advise you to repair yourself, there are several things we can do to help ensure the units function properly and keep them in peak condition. It doesn’t take any experience to clean; the heavier the use of the unit, the more frequently it should be cleaned. Cleaning the inside and outside with hot soapy water is not only sanitary, but it helps your staff to inspect the units to spot potential issues before they become a major concern.  Excess condensation, unusually loud condensers, bad gaskets are all easy to notice and repair if your staff is familiar with the equipment.


With all equipment, visit with your local repair technicians to help you decide on a preventative maintenance program that is right for your business. It is hard to have a clear-cut, adaptable plan for each business since the production and volume of businesses vary so much.


Your food production equipment should also be kept in good condition.  While I think we all would like to believe this is done in our operation, when was the last time you calibrated the fryer to ensure it was actually heating to the temperature you believe it should be?  What about your oven, range, or grill?  Equipment that is too hot will char the outside while leaving the inside raw, while a unit that is too cool while take a longer time to cook the product than what you may have anticipated.  Be sure to clean these items, too.  While we all know the importance of cleaning food contact surfaces, it is also important to clean the underside, sides, and back of the units to maintain peak performance. A cleaning plan developed for the business should always include these areas and be sure to follow-up with your staff on these items.

Last, but not least, be sure your dishwashing equipment is functioning properly. This has even been more important in the last few years with COVID than it has ever been.  Your staff should verify that the machine is operating at the required wash and rinse temperatures often during their shifts. They should also be trained to recognize when equipment is not functioning correctly – and this is something that can be difficult with high staff turnover. I recall one instance in our business where the machine was using a container of detergent every two hours. My first shift dishwasher was new and oblivious top the fact that this was way too much.  It wasn’t until later in the day when my night shift employee caught the issue – which had already cost us hundreds of dollars.

With all equipment, visit with your local repair technicians, they can help you decide on a preventative maintenance program that is right for your business. It is hard to have a clear-cut, adaptable plan for each business since the production and volume of businesses vary so much. Most of these companies want to be a good partner for your business because they want to have a long-term relationship with you.  Remember a little spent on preventative maintenance each year will help alleviate major repairs down the road and ensure your food is kept safe along the continuum of food production.

In May, we will release the second SafeBites Webinar of 2022, so be on the lookout for it.   Be sure to reach out if you have any questions about food safety or have a topic you’d like to learn about in an upcoming SafeBites Webinar or if there is something you’d like me to address through our blogs.

Handling Leafy Green Salad

We have had several produce outbreaks of foodborne disease from our lettuce, spinach, and other greens in the last several years that have been devastating to the produce growers and distributors, retail grocery stores, restaurants, and consumers.

Food Packaging Safety in a Vacuum

Extending the shelf life of fresh foods has come a long way in the food industry since curing meats with salt and sugar or canning vegetables with heat processing. The food service and consumer markets needed some better visual packages to draw the eye to the freshness factor and the technology of food packaging has filled our dinner plate. Vacuum packaging and modified atmosphere packaging, shortened to “MAP”, are the terms used for the method of food packaging used every time we choose convenience over more complex scratch meal preparation. According to industry statistics, billions of packages of vacuum and MAP-packaged foods flood the marketplace today. In both modified-atmosphere and vacuum packaging, food is packaged in a pouch made of barrier film.

The Eleven Commandments of Food Safety at Your Restaurant

Lists help us remember all kinds of information. Given the list of recent national foodborne outbreaks in the news, keep repeating this list to your food service team. They are kind of like “commandments”. As a professional in a food service facility we should think of the very basic food safety concepts that every crew member should aspire to learn, even though this list may have different priorities based on your menu. The first 3 apply to anyone who serves food, from a bag of popcorn to a full course meal. As chefs or managers, if we can “set the example” by repeating good food safety practices visibly to the crew, it will help them understand how important it is to the success of your facility. Thou shalt:

The Worst Customer Complaint: Foodborne Illness

Food service managers and crew try to follow the rules of food protection.  Yet, occasionally a complaint may arise and these calls take priority over all other daily crises.  If you have been in the food service industry long enough, you may have gotten one of these.  A customer may claim, "I think your food made me ill." These words inflict instant anxiety. If it happens, here are some next steps to think about in advance of such a claim:
