But industry executives and some former agency officials said it was unlikely that Congress would enact totally new laws for transgenic animals. And using the drug laws, they say, would provide tighter control than an alternative approach of using the rules governing food additives. Agency officials have said that the veterinary drug rules would be used, and they have already been overseeing some experimental work on that basis. But they continued to debate the issue, and the policy has never been made official.
Another worry is that the F.D.A. might not have enough expertise or authority to conduct a vigorous review of the environmental impact of transgenic animals. The F.D.A. has dismissed this concern, however, saying it has sufficient expertise and can consult with other agencies.
