There are a lot of questions from people about the coronavirus risks in grocery stores and how to stay safe while shopping for food amid the pandemic. Here are answers to some of the common questions.
Skip the gloves, but wear a mask. Don’t sanitize the apples. And if you are older than 65, it’s probably best to still order your groceries online and have a personal shopper deliver them to your door step.
Can I touch the bananas?
Typically, there is currently no evidence of the virus being transmitted by food or food packaging. What you touch on the grocery shelves is less of a concern than who breathes on you and other surfaces you might come in contact with in a store. You may have heard about studies showing that the virus can remain infectious for up to 24 hours on cardboard and up to 72 hours on plastic or stainless steel. These are controlled laboratory studies, in which high levels of infectious virus are applied to the surfaces and humidity and temperature held constant. In these experiments, the level of infectious virus – virus capable of causing disease – decreased even after a few hours, indicating that the virus does not survive well on these surfaces.
The highest risk is close contact with other people who may be shedding virus in droplets as they sneeze, talk or breathe nearby.
Next would be high-touch surfaces, like door handles, where someone not practicing good hand hygiene might have transferred the virus to the surface. In this scenario, you would have to touch this surface and then touch your own mucus membranes – your eyes, mouth or ears – to contract the illness.
Think about how often a surface is touched, and then decide if you can avoid the riskiest spots or use hand sanitizer after touching them. Significantly more people touch door handles and credit card machines compared to a tomato in a bin.
Do I need to sanitize my food when I get home?
Trying to sanitize your food can actually be dangerous. Chemicals and soaps are not labeled for use on food. This means we do not know if they are safe or even effective when directly applied to food.
Moreover, some of these practices might create food safety hazards. For example, if you filled a sink with water and then submerged your vegetables in it, pathogenic microorganisms in your sink – say, trapped in the drain from the raw chicken you cut up the night before – might contaminate your produce.
You should instead wash your produce under cool running water and then dry it with a clean towel.
How should I deal with other people?
We wear masks to protect others. You can have COVID-19 and not know it, so wearing a mask can help keep you from spreading the virus if you’re asymptomatic.
Wearing a mask can also provide some level of protection to the person wearing it, but it does not keep out all droplets and is not 100% effective in preventing disease.
Can I still bring my own bags?
Many grocery outlets have stopped allowing the use of reusable bags because of the potential risks to their workers. In fact, they now prefer to serve their customers through personal shoppers working with several online grocery platforms.
If you are using a reusable nylon or plastic bag, clean inside and outside of the bag with soapy water and rinse. Spray or wipe down the bag inside and out with diluted bleach solution or disinfectant, then allow the bag to air dry completely. For cloth bags, wash the bag in warm water with normal laundry detergent, then dry it on the warmest setting possible.
Everyone has to be more aware of their surroundings to stay safe during this pandemic. Remember to wear your mask and keep your distance from others and you can minimize the risks.
