Commercial milk supply is safe, says FDA

The FDA said that thefragments of the viruswere discoveredwhen thepasteurisedmilk sampleswere tested.

The testing method used iscalledPCR testingwhichlooks for bits of genetic material. If the result ispositive,thatdoesn'tmean they have found a live, infectious virus.

“Based on available information,pasteurisationis likely to inactivate the virus, however, the processis not expectedto remove the presence of viral particles,”said the agency in a releasethat itplans to make public on Tuesday.

“To date, we have seen nothing that would change our assessment that the commercial milk supply is safe.Results from multiple studies will be madeavailable in the next few days to weeks,”added the agency.

Specifically, the FDA is looking at whether bird flu in cow milkis inactivatedbypasteurisation. The findings will be available in the“next few days to weeks,”it stated.

The FDAinitstestingwill use egg inoculation tests, whichare seenas the gold standard to determine if a sample is infectious. In this test, they inject a chicken egg with a small amount of infected milk and observe if the active virus starts to replicate.
