Thawing Food with Food Safety in Mind

There comes a time in almost every foodservice operation where you must thaw food. Yes, I know there are those operations who have moved to fresh products only and don’t have a freezer in-house, but I am willing to bet that is more the exception than the norm. I am almost sure that anyone reading this blog who works in a foodservice operation can regurgitate what methods are acceptable to thaw food per the FDA Model Food Code. In case you don’t recall, I will discuss them briefly, but I wanted to spend some time covering these requirements a bit more in-depth – so you not only know WHAT to do, but the WHY we do it that way.

First, let’s review the food code requirements.  There are three main methods in which food can be thawed by food code standards,

  1. Under refrigeration that maintains the food temperature of 41˚F (5˚C) or less.
  2. Completely submerged under running water at a water temperature of 70˚F (21˚C) or less, with sufficient velocity to agitate and float off loose particles, for a period of time that does not allow the food to raise above 41˚F (5˚C) or if raw animal food that is being thawed, to not allow the food to rise above 41˚F (5˚C) for more than 4 hours.
  3. As part of the cooking process.

Each method of thawing does have its advantages and disadvantages, and each operation, and perhaps each product within an operation, can utilize different thawing methods.


I am sure everyone reading this can agree that thawing food in the refrigerator is the best method of the three. But it is also the method that requires the most forethought and preplanning – something we can’t always account for in the foodservice environment. While most frozen product will require a minimum of 24 hours to thaw, large pieces of meat can require 24 hours for every five pounds of weight. And to cast aside the old wife’s tales you have heard, yes you can refreeze meat if it has been thawed in a safe manner in the refrigerator.

The second method is to use running water and that water should be under 70˚F. This method is certainly faster but does require a bit more effort on the part of the food handler and is somewhat wasteful of water. Before using this, be sure the product is packaged in a way that water will not permeate the package. This will help not only on the food safety side by helping to prevent cross contamination but will maintain peek quality. Why a water temperature below 70˚F? While the reason behind this should be obvious, using water over the 70˚F benchmark can cause the outside of the food to warm to unacceptable levels, which leaves it open to increased bacterial growth. The flow of water also must be sufficient to wash away any loose particles to limit potential cross contamination that could occur.  Besides the food safety aspect behind running water, there is also a practical reason – when you use running water, even if the water is under 70˚F, you are constantly replenishing the supply of heat for the frozen food and thus it will cool more quickly.

Thawing food as part of the cooking process is an often-overlooked method. Perhaps due to cooking methods that are used, but certainly cooking a thin hamburger patty from frozen is viable option, whereas perhaps not so viable with a prime rib roast.  This method would also include microwave thawing, which really just cooks the food at a reduce power level.  For this reason, it is important to fully cook the product if you are using this method and to cool the product appropriately if you will not serve it immediately.

Each method of thawing does have its advantages and disadvantages, and each operation, and perhaps each product within an operation, can utilize different thawing methods. Whichever method you determine is correct for you, be sure you are doing it property and safety.  When in doubt, reach out to your health inspector. I assure you that they would rather visit with you know about your methods than have a foodborne illness outbreak to contend with.

Food Safety Considerations for the “New Way” of Dining, Part II – Back-of-house

In our first blog this month, we discussed the importance of front-of-house practices as we emerge from the pandemic this summer and into fall.   Making your guests feel safe will be an important point as we welcome them back to our establishment.  The safer they feel, the more likely they are to revisit and this could, in turn, be a competitive advantage for your business.

Food Safety Considerations for the “New Way” of Dining

Spring is my favorite time of year, as we head out of the winter months, welcome warmer weather, and increase the daylight hours.  As such, we turnover a new leaf and welcome new life as our grass, trees, and perennials come out of dormancy. This year as the Coronavirus vaccine continues its roll out and we welcome a third vaccine onto the market this morning, perhaps this spring we are turning over a ‘new leaf’ in a much more profound way, as we see light at the end of the Coronavirus tunnel.

Developing Good Food Safety Habits

Good habits and habit development are something that has fascinated me for several years. If you’ve attended any the training programs or presentations that my colleagues and I have conducted through our Center for Food Safety in Child Nutrition Programs, you’ve likely heard me opine about the importance of habits and how habits are created. Many times, in foodservice operations we wonder why our staff don’t follow the food safety practices we have established in our operation. Perhaps they don’t wash their hands when they are required, perhaps they just don’t use the proper method of handwashing, or perhaps we find that they don’t complete our HACCP logs as often as our program dictates should occur. And while we can stomp our feet and say “it is their job, they should just do it”, it really isn’t that simple. We can’t order people to change, although if we could, business and human resources would be so much simpler.

Getting Your Playbook for Food Safety Organized

As anyone who has ever worked in a foodservice operation knows, from the time food is received in your establishment to the time it is served to your customers, following proper food safety practices is crucial. What many don’t often think about is this time really should extend from the time the manager places their orders with their suppliers (including which purveyors you utilize), through the time the food is consumed – even if that consumption occurs off your premises and days after the original order was picked up by the guest. This is something that has certainly been highlighted by the pandemic as customers across the nation are utilizing take-out, curbside to go, and third-party delivery options more so now than ever before.
