Navigating the Intricacies of Temperature Management

I spend a bit of time in these blogs discussing various nuances of food safety – but one that we haven’t spent much time discussing is basic temperature management. I think we all, at least I certainly do, take this knowledge for granted after having been exposed to it for so long. Can you imagine a new hire coming to work in a commercial kitchen for the first time and how confusing all the temperatures we use on a daily basis must be for them?

Temperature management is not just a matter of achieving the perfect doneness in a steak or ensuring a refreshing chill in your salad. It really is a critical factor in safeguarding the health and well-being of anyone who partakes in the creations of a foodservice operation.

At the heart of temperature management is the division between hot and cold, each playing a crucial role in preventing the proliferation of harmful microorganism. The 2022 Model Food Code sets forth specific temperature ranges that food items must be stored, cooked, and held within to minimize the risk of foodborne illnesses. I am basing the rest of my discussion within this blog on that standard.  As always, it is important that you check the standards within your local jurisdiction as they could be slightly different than what the food code has recommended.

Navigating the intricacies of proper temperature control means not only understanding the recommended temperature guidelines, but also implementing best practices in a dynamic and often hectic kitchen environment.

Hot Holding: The magic number here is 135°F (57°C) or higher. Foods like soups, stews, and cooked meats should be maintained at this temperature or above to prevent the growth of dangerous bacteria such as Salmonella and E. coli.

Cold Storage: On the flip side, the chill zone is equally significant. Cold storage, below 41°F (5°C), is vital for perishable foods like dairy, raw meats, and ready-to-eat items. Maintaining these items at the right temperature ensures the slowdown of bacterial growth.

The zone in between the cold and hot zone, or between 41°F (5°C) and 135°F (57°C) is what we have called the temperature danger zone for years.  This zone is the sweet spot for microorganisms to multiple, the temperature at which food should spend as little time as possible.

Cooking Temperatures: When it comes to cooking, temperatures are not just about achieving the ideal taste and texture; they are about ensuring that the food is safe to eat. Poultry, ground meats, and fish have specific temperature thresholds that must be reached to eliminate harmful bacteria. For instance, raw eggs prepared for immediate service should reach 145°F (63°C) poultry should reach an internal temperature of 165°F (74°C), while ground meats and fish should hit 160°F (71°C).

Implementing these temperature management practices in a fast-paced kitchen is no small feat. Chefs and kitchen staff must be adept at multitasking, ensuring that food moves seamlessly through temperature transitions from storage to preparation to cooking and, ultimately, to serving.

The challenges with temperature control are now confounded more than ever with the demand for food delivery and the proliferation of delivery services such as Uber Eats and Grub Hub.  Maintaining the correct temperatures during transportation presents an additional hurdle that requires careful consideration and innovation.

Navigating the intricacies of proper temperature control means not only understanding the recommended temperature guidelines, but also implementing best practices in a dynamic and often hectic kitchen environment. From the storage of ingredients to the final presentation on the plate, each step can have a different temperature requirement which must be met to ensure the food served is not only delicious but, more importantly, safe for every guest. Risk Nothing. 

Evaluating Food Safety

One of the suggestions I made in the last blog was to assess the food safety culture in your organization by observing the food handling techniques of workers. Let’s explore that some more. You can do an overall assessment or you can hone in on specific areas of the operation, such as production or cleaning practices. Remember, when the environmental health inspector visits your operation, he/she just gets a snapshot of what is going on in your operation on that particular day at that specific time. You are there nearly every day, so you have a much better understanding on what really happens in your operation.

September is Food Safety Education Month: The Culture of Food Safety

Developing a culture of food safety is important for any foodservice operation. You may be wondering--just what is a culture of food safety? Let’s start talking about it by first defining what is meant by culture. When you look culture up in the dictionary, you will see terms such as shared knowledge, beliefs, values, attitudes, and meanings; a way of life; patterns of behavior; learned behavior of a group of people; and transmitted from generation to generation. I think these descriptors provide good insight into the meaning of a culture of food safety. You can also think about where you grew up, and a vision of culture comes. For example, I grew up in rural Oklahoma, graduating in the 1970’s with a class of 24 students. My culture instilled in me an appreciation for rural life, hard work, and independence. As I grow older, I realize I haven’t changed very much from my early years, even though I have completed a PhD, lived a lot of places, and traveled throughout the world!

Produce Safety: Special Considerations

In our last blog, I talked about general produce safety. Today, I want to talk about some special products—melons, tomatoes, leafy greens, and sprouts. These are all foods that have a history of bacterial contamination leading to foodborne illness. I also want to discuss salad bars because they have some special risks.
