Grocery stores have become some of the most important retail establishments over the past few months. They’ve kept people fed and provided access to essential supplies such as toilet paper, cleaning agents and over-the-counter medications. Grocery retailers have taken extraordinary steps to help protect the health and safety of their workers and customers during the worldwide pandemic, understanding that viruses can spread quickly with high customer traffic.

While many grocery stores made operational changes to stay open during this time, more adjustments are needed to help stem future infections. Guest occupancy limits, face-covering recommendations and single-directional aisles are here to stay, at least for the near term. Customers are likely to continue online shopping, which has its own set of challenges for food and delivery safety. It will be critical for retailers to obtain reliable information, specific to the store’s location and to follow local, state and federal mitigation guidelines. Trusted sources of such information include the National Institutes of Health (NIH), the CDC and the World Health Organization (WHO), plus state and local health departments.

Grocery retailers should also consider how and when employees interact with customers. Acrylic barriers at checkout lines are one method of physical control. Providing personal protective equipment and appropriate training on its use is another good method for maintaining infection control. As regulations relax, retailers need to evaluate what, if any, other changes should occur to keep safety at the forefront.

There are many other common sense practices retailers can adopt to help minimize the spread of any virus. Viral illnesses spread primarily between individuals, so the most important act of prevention is to keep employees healthy and safe. Hand washing is one of the most important steps we can take to help prevent the spread of illnesses. Most states require grocery stores to post restroom signs mandating that employees wash their hands, but these signs typically lack specific instructions. The CDC recommends cleaning hands in a specific way to avoid getting sick and spreading germs to others. The steps are the following:

1. Dispense a paper towel, so it is ready before wetting hands
2. Wet hands with warm (100°F/38°C) water
3. Apply an appropriate amount of soap
4. Rub hands vigorously together for 20 seconds
5. Clean between the fingers, the backs of the hands and the fingertips
6. Rinse hands under warm water to remove soap
7. Dry hands with the paper towel
8. Turn off faucet with a paper towel
9. Use the paper towel to contact door surfaces to exit
10. Throw away paper towel in a trash receptacle

Because grocery store workers touch food, increasing their handwashing frequency can help prevent the transmission of other types of illnesses beyond respiratory viruses. Employees should take care to wash their hands before donning gloves for any food preparation, after touching exposed skin, after handling soiled utensils and after engaging in any other activities that could soil hands.

Facility sanitization is another essential aspect in preventing the spread of illnesses. Grocery stores already have rigorous cleaning protocols that explain how to mix and use chemicals correctly. Additional instruction on how to apply cleaning agents to surface areas as well as visual reminders reminding workers how long a cleaning solution needs to remain before wiping with a cloth. To prevent the spread of infection, many stores have added more frequent cleaning for high-touch surfaces like door handles, touch screens and carts.

When approved sanitizers run low, however, some people turn to chlorine sanitizing agents like unscented bleach. Bleach can be a highly effective sanitizer, but it can also be potentially hazardous when misused. Specifically, when mixed with other cleaning products that contain ammonia, it creates a highly toxic chlorine gas. The cleaning staff needs proper training on how to mix and use cleaning solutions, use the appropriate personal protective equipment (PPE), such as wearing gloves or a protective outer garment, and to provide appropriate ventilation in rooms where sanitizers are mixed and stored.

Grocery stores have been at the forefront of the pandemic response for some time and they will be the first to adopt “new normal” procedures. Specific guidelines around health and safety evolve, but the fundamentals of health and safety stay the same. Stores that strive to maintain high standards around cleanliness and sanitation are likely to be better positioned for the inevitable next time.
