Keeping up with all the health regulations involved in owning a restaurant is critical, not just for food safety but for the reputation and success of your business. Managers and business owners need to create an environment where safe, proper handwashing procedures are a priority and provide the right tools and techniques to achieve this.

The Importance of Hand Hygiene

Each year, an estimated 48 million people get sick from foodborne illnesses, with Norovirus, Salmonella, and Clostridium perfingens topping the list. Nine out of ten outbreaks in restaurants can be traced back to food handlers and food service workers who didn’t properly wash their hands.

An outbreak that starts in your restaurant could result in serious consequences, including:

  • Prosecution: The Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA) oversee food safety in the U.S. and have strict food safety standards to prevent foodborne illness. If the FDA discovers your restaurant is non-compliant, you could end up with fines, closure, and even jail time.
  • Damaged reputation: When customers — or even worse, the media — discover your restaurant has poor hygiene, they’ll lose respect for your business.
  • Lost revenue: Once customers hear about the problems at your restaurant, they may never return, resulting in lost revenue, not to mention that customers who became sick at your restaurant may sue.
  • Low staff morale: Your staff want to work in a clean, safe environment. If they’re forced to work in unsafe conditions or are responsible for making others sick, they may perform poorly or decide to leave.

So, what’s the best way to prevent foodborne illness? Proper handwashing — it’s as simple as that. 

And yet, an observational study found that food handlers attempted to wash their hands only 32% of their work day. While they were more likely to wash them properly when preparing food (37%), they were less likely to wash them during other activities, like touching their body (27%).

Ensuring Food Safety Through Regulations

Health codes play a vital role in restaurant safety as they provide a standard for best practices that reduce the spread of disease. While handwashing and handwashing sink regulations are governed at the state and local level, many states have adopted the FDA’s Food Code, which outlines best practices for maintaining the health, safety, and hygiene of your staff and customers.

The 2022 version of the Food Code outlines where handwashing sinks must be located, how and when employees should wash their hands, and who is responsible for ensuring employees are effectively washing their hands.

How Food Handlers Should Wash Their Hands

While the CDC has five steps people should follow to wash their hands properly, the Food Code details additional steps food handlers should take to ensure their hands are well-cleaned before, during, and after their shift. All food handlers and food service staff should wash their hands for at least 20 seconds using the following procedure:

  1. Wet hands under clean, running warm water
  2. Apply soap
  3. Rub hands together for at least 10 to 15 seconds
  4. Remove dirt and debris from under fingernails
  5. Rub the soap between the fingers, on the fingertips, the back of the hands, and on any part of the arm that is exposed
  6. Rinse hands using clean, warm running water
  7. Immediately dry hands as thoroughly as possible

When Should Food Handlers Wash Their Hands?

The Food Code recommends that food handlers wash their hands:

  • After touching bare body parts that are not their clean hands or exposed arms
  • After using the bathroom
  • After coughing, sneezing, blowing their nose, smoking, eating or drinking
  • After handling dirty equipment
  • While preparing food to prevent cross-contamination
  • When switching from working with raw meat or poultry to ready-to-eat foods, such as produce

Where Should Food Handlers Wash Their Hands?

Handwashing sink regulations are set at the state and local level, but most states model their requirements on the Food Code. Hand washing sinks in most restaurants must:

  • Be in the food prep, dispensing, and service areas. 
  • Be used only for washing hands; workers cannot wash their hands at a sink that’s used for something other than handwashing
  • Have a faucet with cold and hot running potable water
  • Provide approved soap and single-use paper towels or an air dryer

What About Other Food Handlers?

Restaurants aren’t the only food service industry that should be concerned about proper hand hygiene. Food processors, food manufacturers, and food packers are some examples of industries that have had foodborne illness outbreaks.

While these and other industries are subject to state and local regulations, not all are. If you provide food service in any of the following industries, you may need to comply with handwashing and handwashing sink regulations:

  • Mobile food facilities, including trucks and pushcarts
  • Cottage food
  • Farmer’s markets
  • Temporary or special events (like a carnival)
  • Food processors (like botting water or processing meat)

Ensuring Proper Handwashing

As outlined in the Food Code, someone is responsible for ensuring staff wash their hands properly throughout their shift. This often falls to restaurant owners and managers. Training staff on mandatory regulations and demonstrating the proper way to wash their hands will help ensure your workers understand the importance of hand hygiene.

Teach the Basics

Show new team members critical food safety training and explain how proper handwashing prevents the spread of foodborne illnesses. Visual aids, like videos and posters, can illustrate the steps. Posting signs by handwashing stations reminding staff to wash hands and demonstrating how to wash them properly drives home the importance of good hand hygiene.

Monitor Progress

Assigning a mentor to observe new team members can help them learn how to wash their hands properly. The mentor can provide feedback to new staff and demonstrate the proper way to wash hands. If necessary, retrain new staff members and remind them that they play a key role in preventing outbreaks.

Ongoing Training

While staff may have completed mandatory training to ensure they understand the importance of safe and proper food handling, most food safety training certifications are valid for three to five years. Regular in-house training that includes a refresher on proper handwashing can remind staff how and when to wash their hands and give them the opportunity to ask questions about the process.

Overcoming Common Hand Hygiene Challenges

Though the importance of hand hygiene for food handlers can’t be emphasized enough, studies have shown that people don’t wash their hands as often as they should. Restaurants need to ensure staff wash their hands frequently and properly, and they can take a few steps to overcome some common challenges.

Using the Wrong Sink

Most state handwashing regulations state that handwashing in the food service industry must happen in a dedicated handwashing sink, not a dishwashing or food preparation sink. Using the wrong sink could violate local regulations and result in someone’s hands becoming contaminated, leading to an outbreak.

To prevent someone from washing their hands in the wrong sink, label sinks as handwashing only. A visual cue will help staff use the proper sink for handwashing and prevent mistakes.

Irritated Skin

Frequent hand washing often results in dry, irritated skin. This uncomfortable feeling can cause staff to avoid washing their hands as much as they should. Optimizing workflows so employees wash hands when necessary but not excessively will help, as will providing gentle or moisturizing hand soap.

Lack of Enthusiasm

Not all food handlers understand how important proper handwashing is or are motivated to comply. Continual education will help reinforce the importance of proper hand hygiene, and a reward system may improve behaviors.

Costly

Some restaurants don’t have enough existing plumbing to install an adequate number of sinks. While you can install new lines, this can be an expensive undertaking, not to mention you may have to close your business temporarily. Mobile and temporary food services face similar issues in that there may not be a way to run any plumbing where they operate.

Get Hands Clean

Frequent and proper hand washing by food handlers helps prevent the spread of germs and outbreaks of foodborne illnesses. Educating staff about the importance of proper handwashing and the role they play in keeping everyone safe helps, as does having enough handwashing sinks throughout your business.
