Why it matters: The parasite can ravage herds and disrupt cross-border livestock trade, though officials say it does not make beef unsafe to eat.
What's new: The USDA chief now says the parasite is treatable and not a food-supply risk, even as beef prices and border policy become political flashpoints.
What's new: Officials found 2 more cases in a calf and a dog, while the USDA said it is releasing 10 million sterile flies a week.
Why it matters: The pest can kill livestock through wound infestations, threatening the $113 billion U.S. cattle industry as it moves north from Mexico.
