Unpackaged fruit and vegetables are either peeled before consumption or should be rinsed — and not because of Covid but because of any dust and so on which may be on them.
You should also definitely not wear disposable gloves when shopping — nor in fact for almost any other activity outside health care — as they give a false sense of security, are often porous, and may lead to more contamination than bare hands that are regularly washed and/or sanitised. Instead keep a small bottle of sanitiser at the ready.
If it is present on the packaging it still hasn’t been proven that that virus can actually cause the disease in the people who handle the packaging — it may just be viral particles, pieces of virus instead of an intact virus. When you go shopping, you should rather focus on the people around you and not so much the food in the store. Avoid crowds and shop quickly. When you get home, wash your hands and wash your hands before you eat. Just practice normal hygiene.We don’t really have a scientific basis for making a recommendation. The notion of being paranoid and saying “other people have held this, I’m going to have to clean everything” is being too excessive, in my opinion.
