London, Europe Brief News – A UK study has revealed that the Covid virus can reside on some ready-to-eat groceries for days.
UK experts have carried out tests for the Food Standards Agency (FSA), purposely smearing the virus on to packaging and food products, including fruit, pastries and bottled drinks.
They chose items that people might put in their mouth without cooking or washing.
The risk to consumers remains very low, they say.
Their report says it should be noted that “foods and packaging considered as part of this study were artificially inoculated with Sars-Cov-2 and therefore are not a reflection of contamination levels found on these foods at retail, and lower levels of contamination will require less time to decline to undetectable levels.”
For most food products tested there was a “significant drop” in the levels of virus over the first 24 hours.
But in some cases traces survived for about a week, the University of Southampton team found.
“For a highly infectious agent such as Sars-Cov-2, which can be transmitted through touching contaminated surfaces and then the face, these findings are highly noteworthy,” they say.
“The public may be interested in the finding that virus may persist in an infectious state, on foods and food packaging surfaces, for several days under certain common conditions.”
But they add that there is no need for shoppers to take extra precautions when handling food – other than washing your hands before preparing and eating it, and rinsing fresh produce to help to remove any contamination on the surface.
They picked foods often sold loose at grocery, deli or bakery counters, such as apples, peppers, cheese, ham, olives, crusty bread and croissants.
The packaging tested included drink bottles, cartons and cans.
