Coronaviruses Can Survive on Frozen Meat for a Month


WEDNESDAY, July 13, 2022 (HealthDay Information) — Had COVID? You may need to clear your freezer out.

Researchers mentioned their findings are important as a result of SARS-CoV-2 can reproduce within the intestine, not simply within the respiratory tract the place most individuals really feel its results.

Three virus strains had been used as surrogates within the research, together with two animal coronaviruses. All three have been used as stand-ins in earlier research of SARS-CoV-2.

The researchers discovered that the viruses did not fare as properly in refrigerated temperatures as in freezer temperatures. The numbers additionally differed by meals merchandise.

They mentioned this research underlines the significance of rigorous sanitation within the harvest, transport, packaging and distribution of meals merchandise.
