During the first months of the coronavirus pandemic, there were many doubts about the duration of resistance of the covid-19 virus in food. A criterion of maximum prudence was then chosen, acting as if we were always in the worst scenario.
Now that the pandemic has entered its third year, a study by the University of Southampton for the UK’s Food Standards Agency (FSA) has analyzed (and determined) in which food and packaging stay the coronavirus longer.
To achieve this, they chose products that can be consumed without cooking or washing. The virus was artificially inoculated before the trials, so it can be assumed that much higher than usual levels were studied. When there are lower levels, the time it takes for the virus to clear is also lower.
Scientists have confirmed in their research one of the main hypotheses they used “The the probability of contracting the coronavirus through food is very lowIn any case, experts recommend following a basic safety measure: washing your hands and washing fresh produce.
from one day to one week
As a general rule, Covid-19 takes time to disappear from most foods in about 24 hours. In some cases, however, it may stay a week. This is its “resistance” according to the type of food:
Fresh fruits and vegetables: takes longer to fade on uneven surfaces, such as broccoli or raspberries. However, in those with smooth skin, such as apples, disappears in a shorter period of time, in hours or minutes. In some chilled fresh peppers, they detected the virus up to a week later.
Baked goods: in cakes baked and topped with eggs, the coronavirus begins to disappear after a few hours. the eggs have arachidonic acid and could have a antiviral effect.Meats and cheeses: They are rich in protein and fat. Therefore, covid-19 may remain one week.
Beverage containers and ready meals
The coronavirus survives a different time depending on the material:
Plastic: one week.
Cardboard: several days.
aluminum cans: just a few hours
