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.
Was that last 24 Hour “Bug” You Had Really a Foodborne Illness in Disguise?
Within this blog, I have discussed many foodborne pathogens: E. coli, Hepatitis, Salmonella, Listeria monocytogenes, and Campylobacter. But we’ve somehow managed to omit Staphylococcus aureus (S. aureus).
30 Years Later: The Foodborne Illness Outbreak that Changed Food Safety
In January, we hit a major anniversary. One I am betting snuck by many of you – including me! January marked 30 years since the deadly 1993 E. coli O157:H7 outbreak at Jack in the Box restaurants on the west coast. The anniversary wasn’t on any of the major news networks that I recall. It did make it into a few newspapers, at least one or two of the newspapers that are left. It wasn’t until late-February that I realized it.
Does Temperature Really Matter when Washing your Hands?
In January, I reviewed the changes to the 2022 Food Code in my blog (check out Part I and Part II), and one change to the food code that I had mentioned, but didn’t discuss in-depth, was the change that lowered the water temperature a hand sink was required to produce to 85°F, as noted in Section 2-202.12 of the code. This requirement has been in place since the publishing of the 2001 Food Code, which required a water temperature of 100°F. Prior to this, 110°F was required (see the 1999 Food Code). So why the change and does water temperature when washing your hands really matter?
Hand sinks: Often Taken for Granted, but an Essential Part to Effective Hand Hygiene
Late in January, I received a question about hand sinks in a foodservice operation. The question pertained to school staff (teachers and aides) who were using a hand washing sink in the school kitchen. The question came as a matter of who was allowed access to the kitchen to use the sink, but the question itself caused me to go down a rabbit hole of requirements for hand washing sinks in foodservice operations.
