10 Mistakes You’re Probably Making Cleaning Groceries

Like their counterparts delivering ready-made food from restaurants, virtually all grocery delivery services offer no-contact delivery. That means that your order is left on your doorstep, eliminating the need for you to have any direct interaction with the delivery person. Some services consider no-contact delivery the default option, but in other cases you may need to specifically request it when you order.

Once you bring your order inside, where do you put it? If you just set it down on the counter and then don’t thoroughly disinfect the surface later, you’re taking a chance of contamination. Before bringing things inside, designate a defined area so you know exactly what to clean when you’re finished. Some people use their kitchen sink, because it’s easier to disinfect. Others clear off a portion of the counter or dining room table. (To make cleanup easier, you can also spread newspaper on the surface before setting anything down, then carefully discard the paper when you’re done.)

You’ve heard this time and again in recent months, but you can’t wash your hands often enough. Other than breathing in the virus, the most common method of transmission is apparently through touching an infected surface and then touching your face. We all touch our faces more often than we realize, so the cleaner our hands are at all times, the better. After you’ve unpacked but before you start cleaning, wash your hands in warm water, with soap, for at least 20 seconds.

Some food safety experts think disinfecting groceries is being overly cautious, but to be safe — and remembering that your food has probably been touched by at least a few people (stock clerks, other customers, your delivery shopper) — it’s a good idea to thoroughly wash packaging or swab it with a disinfectant wipe, and to wash produce thoroughly.

Chemical wipes and sprays are great tools for disinfecting surfaces, from countertops to food packaging to anything else that people regularly touch (door handles, light switches, etc.). It emphatically should not be used on fruits and vegetables, however, or directly on anything else you plan to eat (the surface of meats, for example). Even if you wash items after using disinfectants, some residue might remain, and it can make you sick.

Since you can’t use disinfectant on produce, should you wash it with soap and water as you would your hands? No, say experts like Don Schaffner, a Rutgers professor of food microbiology and host of the podcast “Food Safety Talk.” “Accidentally ingesting soap can cause nausea, vomiting, and diarrhea,” says Schaffner. Instead, rinse it thoroughly in warm water, using your hands or (for sturdy produce) a brush, then pat it dry with paper towels.

Once everything is out of the bags or boxes, what do you do with them? Whether you plan to reuse them yourself or recycle them, let them sit, out of the way, to allow any harmful residue to dissipate. According to a recent British study, the coronavirus can live on paper for three hours and on cardboard for up to 24, so after that they should be safe to handle.

Once you’ve got everything unpacked and put away, remember to use disinfectant (spray or a wipe) on the service the bags or boxes were sitting on, just to be extra careful.

Now comes the last important step. You guessed it: washing your hands again, using warm water and soap, for at least 20 seconds. Numerous online tutorials demonstrate the best techniques.

One final note: You’re cleaning your groceries because you want to be especially cautious, and that’s a good thing. But don’t get crazy about it. Every tiny corner of every package doesn’t need attention (concentrate on the parts that people would normally hold when picking it up), and as long as you wash your hands thoroughly (and often), your chances of picking up the virus from the surfaces of groceries or anything else are small.
