UNDERSTANDING TIME AS A CONTROL FOR PUBLIC HEALTH
Much of our business that revolves around food safety is governed by temperatures. The endpoint cooking temperature of ground beef, the hot holding temperature on the line, the temperature of our refrigerators, or what the key temperatures are for cooling – the temperatures that many of us can recite in our sleep. But there are times when temperature control is just simply not possible. I remember several instances in my foodservice life where we didn’t have the luxury of having refrigeration, or where we were catering an outdoor event, and no matter how “windproof” our sternos and chaffing dishes were meant to be, the brisk Iowa wind would blow out the flame. This is where the food code section on time as a public health control comes into play.
Last week, I was helping with the development of a food safety exam, and I was reminded of just how confusing and misunderstood this section of the food code could be – for employees, managers, and seasoned professionals, alike. The code spells out this information in Section 3-501.19.
We all know that hot food must be kept at a temperature greater than 135˚F and cold food less than 41˚F, but at times when you are not able to maintain those temperatures, the code allows you to use time to keep food safe. To use this provision of the code, you do have to have a written procedure that you have prepared in advance, which can be made available to the inspector if they inquire about your procedures.
WE ALL KNOW THAT HOT FOOD MUST BE KEPT AT A TEMPERATURE GREATER THAN 135˚F OR LESS THAN 41˚F, BUT WHEN YOU ARE NOT ABLE TO MAINTAIN THOSE TEMPERATURES, THE CODE ALLOWS YOU TO USE TIME AS A MEASURE TO KEEP FOOD SAFE.
The next requirement is to make sure you have held the food properly at the correct temperature before you remove it from temperature control. In the case of hot food, it should be held at a temperature greater than 135˚F and cold food should have been kept at a temperature less than 41˚F.
Then, once it is removed from temperature control (for example, placed on a buffet line), record the time of when it was removed from temperature control and when it must be discarded. Once the four-hour mark has been reached, the food must have been served or discarded. It cannot be reheated to temperature and saved, or served again, it must be discarded.
There is, however, also a provision in the code that allows you to keep food for up to a maximum of six hours. This is only permissible for cold food (that is, food removed from temperature control at 41˚F or less). Again, the food shall be marked with the time at which it was removed from temperature control and the time at which the six-hour point will be met, at which point the food must be either served, cooked and served, or discarded. However, the food at no point shall exceed 70˚F during this six-hour period. Once the food exceeds the 70˚F point, it must be discarded.
Now for the usual disclaimer that I add at any time I discuss the food code. It is vital that you know your local food code and if the time as a public health control is allowed for in your specific jurisdiction and if there are any specific nuances that differs from the Model Food Code, which is what I base all of my blogs off, currently the 2022 code. Each jurisdiction has the ability to adopt any part of the model code or amend it to fit their standards, so when it doubt, call your inspector. Risk Nothing.
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.
The Route to Safer Fresh Fruits and Vegetables
Although fruits and vegetables are one of the healthiest foods sources in our diet, we continue to have foodborne disease outbreaks of significance from produce, sometimes affecting large groups of people in multiple states because of their wide distribution. The CDC estimates that fresh produce now causes a huge number of foodborne illness outbreaks in the United States. Produce needs our continued food safety efforts at the restaurant level as well as at the stages in agricultural production. Occasionally, fresh fruits and vegetables can become contaminated with harmful bacteria or viruses, such as Salmonella, E. coli 0157:H7, Norovirus, and Hepatitis A. This contamination can occur at any point from the field to our table. If eaten, contaminated fruits and vegetables can cause foodborne illness.
Be Cool, Chill Out, Refrigerate Promptly!
The Cold Chain -- Keeping perishable foods at proper cold holding temperatures (between 28°F and 41°F maximum or 0°F for frozen food) from your food producers / manufacturers to your customers has to be one of our strongest links to safe food and high quality. Sometimes that is referred to in the food industry as “maintaining the COLD CHAIN”. Any slip ups in the cold chain, and we have a weak link. Most all of our state food regulations require 41°F as a cold maximum, but colder is a “best practice” policy to maintain.
