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!

How Effective is Your Food Safety Training?

Basic food safety in a restaurant kitchen is not rocket science, but critically important for the crew to take the time to learn about it and for managers to set the example each day.  Customers never expect or want to see a manager, chef, or a crew member make a very visible food safety mistake, like not washing hands before food prep and gloving, or touching their face or hair while prepping or handling food.  Have we all seen it happen in our restaurant or as a customer elsewhere? Certainly.  Are you using some creativity in your current training methods to help your staff “get it” so to speak, and reflect positive behaviors regarding food safety?

Why Does Food Spoil?

Food gradually deteriorates because of a natural process of aging, just like humans. However with all foods, there are a few things we can do that have a positive effect on the shelf life and safety of our foods at the restaurant. Some preservation is done at the food manufacturing plant, some naturally, but a better understanding of the processes may help you extend that shelf life. Preservation methods and storage conditions must be designed to reduce the rate of decomposition and protect the safety, appearance and taste of our food.
