No, You Don't Need To Disinfect Your Groceries. But Here's How To Shop Safely
Many shoppers are now following elaborate routines to disinfect their groceries, thanks to a viral video put out by a Michigan family doctor. But all of the experts we spoke with say that disinfecting and hand-washing every last item in your grocery haul is really not necessary. You might find it comforting to know that none of these experts are doing this themselves.
Rasmussen explains that the probability of getting infected from a contaminated surface is not zero, but it is fairly low. That's because respiratory droplets would have to have landed on the exact spot on, say, a box of cereal that you are touching. And even then, you'd have to get enough residual virus on your hand to start an infection — and you'd have to transfer that virus to your face. Bottom line: If you follow good hand-hygiene practices — washing your hands after unpacking your groceries, before cooking and before eating — then, she says, your risk is probably "very, very low."
As Aronoff notes, "Time is really on your side here." That's because as soon as the virus lands on a surface, it starts to lose infectiousness. "After 24 hours, the vast majority of virus is no longer infectious," he says. And after 72 hours, he notes that research has found the virus is
trace or
undetectable on most surfaces. So if you know that you're not going to use a can of soup for two or three days, he says, just put it away, wash your hands and go about your day. And one more thing: Make sure to wipe down your countertops after you unpack.
If you're still worried and it's a food that doesn't need to be refrigerated, Graham says just leave it out for 24 hours.
