From the same people who brought you the original ruminant feed ban that decreed that cows shouldn't eat dead cows, comes a tightening of those rules. So remember when a BSE-infected cow was discovered in the US? And the FDA put into effect a ruminant feed ban that decreed that cows shouldn't eat dead cows? Well that apparently didn't work so well, since they (the FDA) has decided that those rules should be tightened. They're finally addressing a massive loophole that allowed feed producers to put dead cows in chicken feed, and then to put dead chickens that had eaten that feed into cow feed. It made the prions jump an extra step between generations, but the prions seem to be up to that. Bloomberg has more:
The revisions will be the first tightening of the rules since the FDA barred feeding cattle parts to cattle in 1997. The FDA has considered and then abandoned stronger measures for preventing the brain-wasting disease, also called bovine spongiform encephalopathy, said Representative Rosa DeLauro, the top Democrat on the House panel that oversees the FDA budget.
``We have been operating under rules from 1997, even though our understanding of how BSE is spread has increased dramatically since then,'' DeLauro, of Connecticut, told Acting FDA Commissioner Andrew von Eschenbach at a subcommittee meeting today on the agency's budget.
