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.

Hand sinks are, perhaps, taken for granted by many managers, supervisors, and employees in foodservice operations when it comes to reviewing hand washing effectiveness. They are easy to take for granted, until they are not working. Even in these blogs, we’ve focused on the correct procedure for washing your hands, when to wash hands, and hand washing supplies, but we don’t often focus on the hand sink.

The FDA Model Food Code states at least one hand sink should be available to employees.  Further recommendations are that the sink should be convenient for employees who participate in food preparation, dispensing, and ware washing and there should be a hand sink immediately adjacent to restrooms.


…employees are more likely to wash their hands if the operation has more than one handwashing sink and/or a sink is located within the sight of the employee.


Our previous research has found that one big barrier to employees washing their hands is how convenient the sink is to their work area. Remember that your definition of convenient and your employees may very well differ. I once had one of my employees tell me that he can’t wash his hands as many times as he would need to by “the code”, simply because it takes too much time, and we expected him to get food out to our guests in a timely manner.  Even though our management team thought that both hand washing sinks in the kitchen were convenient for all of our employees, employee perception didn’t agree – and it was the employees’ perception that really mattered as they were the ones working in that area 40 hours a week.

Other research in the field has also found employees are more likely to wash their hands if the operation has more than one hand washing sink and/or a sink is located within the sight of the employee. So how many is enough in your operation?  The food code doesn’t give a straight answer to that question because it really does depend on your business.  For a small-scale, limited production kitchen, one sink may very well be enough.  However, for larger operations with complex food production, many sinks would be desired and recommended.

Solid recommendations on the number of sinks required are difficult to come by.  Foodservice Equipment and Supplies Magazine noted that you should allow one hand sink for every five employees working in your kitchen at a time.  Further, they noted that one hand sink should be planned for every 300 square feet of kitchen space, and one hand sink for each foodservice preparation and/or cooking area.  These recommendations align with research in the area and would certainly mean that the hand washing sink is convenient and in view of each employee in the production area.

While this is great information to have, many who are reading this are likely dealing with kitchens that are already built and unable to easily renovate spaces to accommodate more hand washing sinks. In this case, it is imperative that we try to reinforce the importance of hand washing with our employees and remove any barriers they may have to washing their hands. Only then will employees start to change their behaviors and improve hand washing compliance.

Later this month, be on the lookout for the SafeBites Webinar Series announcements for 2023.  We have an exciting set of webinars that we are planning this year. In the meantime, if you have any food safety questions, we are a quick email away and would be happy to assist. Risk Nothing. 

Proper Cooking Temperature: A Basic Food Safety Measure

Each summer, we see an increase in the incidence of foodborne illnesses. Perhaps this is because of the warmer temperatures making temperature control for Time/Temperature Control for Safety (TCS) food more difficult or perhaps it is the increased amount of people who are barbequing this time of year – it is National Picnic Month, after all!

Changing Climate: The Unseen Impact on Food Safety

In June, I was asked to participate in the Allinfoodz podcast, put on by a colleague, Dr. Amit Sharma, at Penn State University.  One of the points Dr. Sharma wanted to discuss was the impact of climate change on food safety, which is something I was certainly aware of, but not something I had done much research on.  However, when preparing for the interview and podcast, it was interesting to learn more about the relationship between the two.

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.

Addressing Major Food Recalls in Your Business

It seems like every year we have a large-scale food recall that reminds consumers and foodservice operators about the importance of food safety. Not that we need reminded, but it certainly puts the topic in the headlines again. Last year, it was the onion recall. This year, it may very well be the Jiff peanut butter recall, of which we are in the midst of.  At the time of the publishing, we are starting to learn more about a potential hepatitis A outbreak linked to strawberries.  If you have not been impacted by either of these recalls in your personal or business life, I would be surprised.
