David O’Connor, a virologist on the College of Wisconsin-Madison, stated discovering viral fragments in milk from business provide chains is just not supreme, however the genetic materials poses little danger to shoppers consuming the milk.
“There must be no danger of an infection from milk that accommodates viral fragments,” he stated. “Genetic materials can not replicate itself.”
