Handwashing 101
During the last several months, we have all heard about the importance of hand hygiene. Food service folks have long known that our mothers were right – washing your hands with soap is an excellent preventative step in avoiding illness. Now with COVID, there is more messaging that ever before about handwashing and avoiding cross contamination from unclean surfaces. Those with a tendency for germaphobia (yours truly, by the way) may have noticed this deepening to close to obsessive levels! In fact, carrying one’s own tool kit of disinfecting wipes and hand sanitizer is now the cool thing to do. No surprise that shortages of these supplies at the retail level, along with toilet paper, are voiced loud and clear via social media.
In looking for something positive from the pandemic (we are both glass half full types!), increased awareness about hand hygiene and cross contamination are beneficial outcomes. The how and when of correct handwashing is almost a mantra for those in foodservice. The recipe is to use clean water, later with soap for 10 to 15 seconds, rinse with water, and then dry with either a disposable towel or hot air dryer. While air dryers are environmentally preferred, having a disposable towel handy to turn off faucets, if not automated, and/or open the restroom door to exit and keep clean hands clean is advantageous. Plus, research has shown the abrasion of the towel further reduces microbial load on the hands.[1]
When to wash hands is clearly specified in the FDA Food Code. Per Code, hands should be washed: when entering the kitchen, before beginning food preparation or eating, after touching any soiled item or unclean surfaces, handling raw protein foods, using the restroom, taking out garbage, and working with chemicals. Putting this into practice is a challenge. For instance, a staff member exits the kitchen to use the restroom so hands should be washed in the restroom as well as immediately after reentering the kitchen. Most surfaces in the kitchen area are kept clean and sanitized, but there are the hidden touch points, such as refrigerator door handles, that may not be included in daily cleaning schedules and should necessitate a handwashing after touching. Other surfaces get touched so frequently, it is a challenge to keep them free of any harmful microorganisms. Our former colleague, Dr. Jeannie Sneed, led a couple of research projects documenting microbial loads on different kitchen surfaces, with findings published in several peer-reviewed journals and used in creating the YUCK photos housed on the Iowa State University Food Safety Project web page (available as a free download). Refrigerator handles were found to harbor lots of pathogenic microorganisms in various kitchens!
Another challenge is that jobs may require frequent changes from handling “clean” surfaces (i.e. serving a plated meal) to those that are “dirty”, such as removing soiled dishware from the table and taking to the dish room. This can be especially true for front-of-house staff in full service restaurants. At K-State, Kevin’s group has developed messaging about handwashing that can help reinforce the importance of handwashing. Moreover, FoodHandler has some great videos (each about 5 minutes in length, so perfect for training) about handwashing and other hand hygiene practices.
In the second blog this month, we will discuss some strategies to minimize the need for handwashing occasions, while still maintaining good hand hygiene. Join us for the SafeBites webinar on September 16th for a deeper look about hand hygiene.
Hand hygiene is one way to control from risks of illness. As we say at FoodHandler – 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.
