Why Cooling Foods Correctly Isn’t Something to Chill Out Over
Twenty-eight years ago last month, Kevin began his career in the foodservice industry. He started as an assistant prep cook in an independent owned restaurant in Iowa. Like many of you, he remembers his first few days just like it was yesterday. Having never stepped foot in a commercial kitchen, it was a whirlwind of learning. He was trained to do so many “new” things in those first few weeks, dishing up salads, cleaning and peeling ridiculous amounts of carrots and onions, closely following recipes to make steam-jacketed kettles full of chili, spaghetti sauce, or any one of a variety of homemade soups. He also faintly recalls the discussion of cooling those soups, which were cooked in bulk, cooled, and re-heated in smaller batches for service over the course of a few days. Back then, the discussion went something like this, “after cooking, we put the [insert name of soup or sauce here] into these two-gallon storage containers and place it in the cooler as quickly as possible. We never put the lid on, we leave it askew so we can let heat out. About an hour or so later, we can put the lid on and label it.”
Back then, that conversation made perfect sense. Kevin grew up participating in Foods and Nutrition projects in 4-H, so he was aware of the basics of food safety. Flash forward about 5½ years to the spring of 1997 when he was a freshman in Dr. Cathy Strohbehn’s HRI 293, Hospitality Sanitation course at Iowa State University (in which he earned an A, by the way!😁). This was his first indication that perhaps the practices used at the restaurant were not as foolproof as he once thought they might be.
… improper cooling practices contributed to 504 outbreaks associated with restaurants or delis.
-Centers for Disease Control and Prevention
Flash forward another 20 years, and Kevin was at Kansas State University and working with a very talented team of researchers to complete a cooling study as part of the Center for Food Safety in Child Nutrition Programs (which include the National School Lunch and Breakfast Programs). Their focus was to replicate practices observed in school nutrition operations, which were not necessarily best practices. [If you need some reading material to put you to sleep at night, we will post the publications that resulted from these studies at the end of the blog for this month. 😂] As many of you likely know, the Food Code requires hot, temperature controlled for safety foods be lowered from a temperature above 135°F to below 70°F in two hours, and then reach below 41°F within a combined total of six hours. The researchers used various cooling methods and products and learned very quickly that even reducing food hot-off-the-stove to a 2” depth and placing it directly in the cooler was not going to be sufficient to meet the FDA Food Fode requirements. One of the methods tested was to place a 128oz Rapi-Kool™ into a stock pot of chili. This is NOT the proper way to use a Rapi-Kool™, but it was done to replicate a cook who may be anxious to go home at the end of their shift and simply placed the Rapi-Kool™ in the pot of chili and went home, assuming that it would cool the chili properly. While the researchers didn’t necessarily think it would meet the FDA requirements, it took an astonishing 24+ hours to cool! In defense of the Rapi-Kool, that product works great in an active cooling scenario (in which the cool stick is agitated or used to stir the product periodically through the cooling cycle), but again, they are not designed as a passive cooling device.
Many operators may be reading this and wondering if cooling is really that big of an issue with regards to foodborne illness outbreaks. The Centers for Disease Control and Prevention notes that between 1998 and 2008, improper cooling practices contributed to 504 outbreaks associated with restaurants or delis. An article in Science Daily back in 2000 even noted that improper cooling is thought to be the top cause of foodborne illnesses in the United States. Improper cooling continues to stay on the list of the top five reasons why foodborne illnesses occur.
Have the cooling practices used in your operation been given a thorough review? Do employees know the correct way to cool products that ensures there is no temperature abuse? Join us for our November webinar, Chill Out! Implementing Safe Food Cooling Practices with Dr. Paola Paez, Kevin’s colleague from the Center for Food Safety Research at Kansas State University, and learn a few strategies to implement correct cooling practices in your foodservice. Cooling food properly isn’t something that should be taken for granted and simply chill out over. It also isn’t something that requires a large investment, except in knowledge. Know that your cooling practices work for your business. Risk Nothing.

Be Aware When You Prepare – Food Prep Tips
The subject of food preparation covers some very broad, basic principles within food safety, with many steps associated with “risk” in some recipes. Certainly, preparation steps are where the most mistakes have occurred if a foodborne illness should occur. Outbreaks usually happen when more than one mistake occurs during prep, but sometimes it only takes one. Cooking is the biggest risk for raw foods, but all foods become ready-to-eat foods at some point in final preparation steps and that’s where the most care is required.
Food Gloves & Latex Allergy Education
Politicians joke about the endless stretch of rubber chicken dinners they may consume in an election year. For people with a latex allergy, such a prospect may be no laughing matter. While latex serves as an effective barrier glove material and has the best fit because of its elasticity, the risks associated should not be ignored. The solution is not simple and many options are available for operators today. It should always be mentioned that handwashing (before putting on gloves) is always the primary barrier to contamination and gloves are considered a good secondary barrier.
Foodborne Illness Myths & Facts
“It must have been something I ate.” That’s the typical statement when a person develops some relatively minor symptoms from food. Maybe not severe enough to go to the doctor so you choose to tough it out without medical care. Sudden onset of flu-like symptoms such as onset of stomach cramps, diarrhea, vomiting and fever could possibly mean you are the victim of a foodborne illness. The illness is sometimes referred to as “food poisoning”, but it’s often misdiagnosed.
Don’t Compromise: Clean and Sanitize
The subject is cleaning and sanitizing. Chefs, food service directors, managers and staff try to practice safe food-handling at every turn in the kitchen. Don’t let that effort go down the drain by slacking off on the many aspects of sanitation. That includes dish and ware-washing techniques (pots, pans, equipment), and cleaning all the areas that give us that “neat as a pin” appearance in your customers eyes. Customers seldom fail to bring that soiled silverware or glass with lipstick on it to the attention of the manager or wait staff. Improperly cleaning and sanitizing of food contact equipment does allow transmission of pathogenic microorganisms to food and ultimately our customer.
