The action follows new research finding portions of a cow’s intestines that were previously thought to be immune from bovine spongiform encephalopathy, also known as mad cow disease, show signs of “infectivity.”
Since then, peer-reviewed science has found other parts of cow intestines and colons could also carry the disease, though the danger is believed to be low, according to FDA.
“We tentatively conclude that the effect of these traces of infectivity on the risk of human or ruminant exposure to BSE in the United States is negligible,” the agency wrote.
Still, officials are reopening the public comment period, as they consider strengthening the rule in light of the new research. Monday begins the start of a new 60-day comment period.
