Do You Need To Wash Groceries & Safe Shopping Tips

(The Guardian, April 2) The coronavirus is thought to spread largely via person-to-person contact, but it can also live on surfaces – including food packaging – for several days. While some how-to videos and articles are encouraging people to disinfect grocery containers, mail and other packages entering the home, experts say that is probably overkill.

Below are step-by-step tips from experts about how to get what you need from the store and limit your exposure to the virus as much as possible.

- Limit your trips and go when stores are less crowded

Experts advise limiting grocery trips to once every two weeks, if possible. This may mean stocking up on dry goods, and frozen or canned fruits and vegetables. If you can, plan to shop during off-peak hours. Some stores are setting aside times for older and immunocompromised people to shop with reduced crowds. Keep a distance of at least six feet from other shoppers. Plan what you need before you go to minimize your time in the supermarket.

- Clean your hands and disinfect your cart

“As soon as you get there, use hand sanitizer, and touch only what you need to touch. Wipe down your cart handle, and then use the hand sanitizer again,” said Elizabeth Eckstrom, professor and chief of geriatrics at Oregon Health and Science University.

Shoppers should also avoid touching their phones or wipe them down after any possible contamination, said Julia Marcus, an infectious disease epidemiologist and professor in the department of population medicine at Harvard Medical School. Gloves are not necessary, she said. “Generally when we use gloves outside of the healthcare setting and just in the community, they tend to become like a second skin. We end up touching our faces, and they may actually make us feel like we’re not at risk but they themselves can become contaminated and may actually be a better surface for the virus to persist on than our own skin,” she said.



- You don’t need to sanitize food packaging

While the coronavirus is not thought to be transmissible via food, it can live for several days on materials used to package food. Preliminary research shows it can survive on cardboard for 24 hours and on plastic for 72 hours. But the amount of the virus also quickly declines during that time period.

The US Centers for Disease Control currently does not recommend disinfecting packaging. And Marcus said shoppers should instead thoroughly wash their hands after handling any item that might have been touched by others. “At this point, there’s no evidence that transmission is happening through food packaging. That said, we know the virus can remain viable on surfaces for hours or even days, so there’s a hypothetical risk of transmission through touching a contaminated surface and then touching your eyes, nose or mouth,” Marcus said. “Better than disinfecting, the thing we keep saying over and over again is to just wash your hands.”

Donald W Schaffner, a food microbiologist and professor at Rutgers University, has firmly pushed back on viral advice for people to disinfect food packaging. “Right now there’s no evidence that [the virus is] spread through food. There’s no evidence that it’s spread through food packaging. That doesn’t mean that we might not learn new evidence tomorrow that would change our thoughts on that, but right now that’s what we believe,” Schaffner said...

**Wash nonporous containers. The FDA says there's no current evidence to support the transmission of the virus from food packaging. But if you're concerned, it can't hurt to wipe down non-porous containers like glass or cans with disinfectant wipes.

If that's not practical, wash your hands well after putting away all packaging, including paper boxes and bags. "It all comes down to hand hygiene," says Liz Garman, a spokesperson for the Association for Professionals in Infection Control and Epidemiology in Arlington, Va.
It also doesn't hurt to wash your hands after opening the containers and using their contents.

"But if you use a pasta box a few days after you get it, there is little likelihood that the virus could still be live on the box and cause an infection," says Eike Steinmann, a virologist at Ruhr-Universitat Bochum in Germany who has studied how long viruses live on different surfaces. One preliminary study found that the coronavirus responsible for the current pandemic doesn't survive on cardboard longer than 24 hours...
