Covid Virus May Survive For 30 Days On Refrigerated, Frozen Meat: Study



The SARS-CoV-2 virus, which causes COVID-19, might survive on meat and fish merchandise within the fridge or the freezer for as much as 30 days, a research suggests. The analysis, not too long ago printed within the journal Utilized and Environmental Microbiology, was performed utilizing hen, beef, pork, and salmon, and surrogate viruses with spikes much like these on SARS-CoV-2.

The researchers saved the meat and fish merchandise at each refrigeration (4 levels Celsius) and freezer temperatures (minus 20 levels C).

“Though you won’t retailer meat within the fridge for 30 days, you may retailer it within the freezer for that lengthy,” mentioned research first creator Emily S. Bailey, an assistant professor at Campbell College within the US.

“We even discovered that the viruses may very well be cultured after (being frozen for) that size of time,” Bailey mentioned in an announcement. The researchers undertook the research after studying that COVID-19 outbreaks had been occurring in Southeast Asia previous to group transmission.

Studies from these communities “instructed that packaged meat merchandise, produced in areas the place SARS-CoV-2 was circulating, might have been the supply of the virus,” mentioned Bailey.

“Our aim was to analyze whether or not or not comparable viruses might survive on this atmosphere,” she mentioned. The analysis is essential as a result of SARS-CoV-2 can replicate throughout the intestine, in addition to within the respiratory tract, mentioned Bailey.

Within the research, the researchers used one RNA virus with a lipid envelop, and two animal coronaviruses-murine hepatitis virus and transmissible gastroenteritis virus as surrogates.

All three viruses have beforehand been used as surrogates for SARS-CoV-2, usually with larger reductions of their numbers noticed at refrigeration than at freezing temperatures.

The discount in numbers additionally assorted in accordance with the meals merchandise used. “Steady efforts are wanted to forestall contamination of meals and meals processing surfaces, employee fingers, and meals processing utensils equivalent to knives,” the researchers famous.

“The shortage of, or insufficient, disinfection of those meals previous to packaging must be addressed,” they added.
