WEDNESDAY, July 13, 2022 (HealthDay Information) — Had COVID? You could wish to blank your freezer out.
A brand new learn about means that cousins of the SARS-CoV-2 virus can live to tell the tale on frozen meat and fish for as much as 30 days.
The analysis — caused through COVID outbreaks in Asia wherein packaged meat used to be suspected because the virus’ supply — used to be carried out on frozen rooster, pork, red meat and salmon. The findings have been printed June 11 in Implemented and Environmental Microbiology , a magazine of the American Society for Microbiology.
“Although you might not store meat in the fridge for 30 days, you might store it in the freezer for that long,” mentioned first writer Emily Bailey, assistant professor of public well being at Campbell College in Buies Creek, N.C.
Her group carried out its analysis with out use of the particular coronavirus that reasons COVID-19. As a substitute, researchers depended on surrogate viruses with identical protein spikes.
Those identical viruses have been put on frozen meat and fish, which used to be then saved in each fridge temperatures (39.2 levels Fahrenheit) and freezer temperatures (-4 F.)
“We even found that the viruses could be cultured after [being frozen for] that length of time,” Bailey mentioned in a magazine information liberate.
Researchers mentioned their findings are important as a result of SARS-CoV-2 can reproduce within the intestine, no longer simply within the breathing tract the place the general public really feel its results.
3 virus traces have been used as surrogates within the learn about, together with two animal coronaviruses. All 3 had been used as stand-ins in earlier research of SARS-CoV-2.
The researchers discovered that the viruses did not fare as neatly in refrigerated temperatures as in freezer temperatures. The numbers additionally differed through meals merchandise.
They mentioned this learn about underlines the significance of rigorous sanitation within the harvest, delivery, packaging and distribution of meals merchandise.
“Continued efforts are needed to prevent contamination of foods and food processing surfaces, worker hands, and food processing utensils such as knives,” the authors wrote, including that the disinfection of meals previous to packaging additionally must be addressed.
