U.S. farmers and dairy processors will have to start providing samples or raw milk at the government's request after the Department of Agriculture announced new rules for the country's supply due to increasing bird flu concerns.

However, experts believe the figure is a vast underestimation given the absence of mandatory testing, something harshly criticized by experts including the World Health Organization (WHO).
