A “triple firewall” of protection has reduced the chances of bovine spongiform encephalopathy (BSE), or Mad Cow Disease, showing up in U.S. livestock, according to James Hodges, president of the American Meat Institute Foundation.

“Our risks today of BSE are lower than they’ve ever been since we understood the threat the disease presented to us,” he told the North American Agricultural Journalists’ semi-annual meeting.

“It’s perplexing to me to see the focus on all of the things we’ve done wrong rather than all of the things we’ve done right to prevent BSE,” he added.

A “triple firewall” of import controls, surveillance and animal-feed controls work together to insulate U.S. livestock from this disease, he said.
