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. 

Don’t Underestimate the Importance of Employee Health as we head into the Winter Months

Early this month, I ran across an article discussing an outbreak investigation in the Australian Capital Territory. The outbreak caused more than 200 people to fall ill and was one of the most widespread outbreak investigations in the history of the territory.  The cause was traced back to Norovirus, a virus I am sure you have heard us opine about in this blog before.

Exclusion and Restrictions: Understanding Employee Health and the Food Code

I received a call earlier in the month from a foodservice operator who suspected that one of their employees may have fallen ill and wondered if they had to send the employee home for the day.  Once I started to ask a few more questions, it became obvious that the operator wasn’t really in-tune with the food code requirements on restrictions or exclusions for employees who may not be feeling well.  Given that most operations are dealing with staff shortages currently and the fact that we are about to head into the fall and winter – when we tend to see an increase in upper respiratory and other illnesses, such as the flu - it seemed like a very timely and important topic for the blog this month.

Cross Contamination and the Surfaces that go Unnoticed

In October, I ran across a new research study published in the Journal of Food Protection in early-September.  The article explored cross contamination in consumer kitchens during meal preparation. One of the authors was a previous SafeBites presenter, Dr. Ellen Shumaker, at North Carolina State University.  Although the setting was consumer kitchens and not the commercial kitchen many of you deal with daily, the findings were very applicable to what we often see in the foodservice setting.
