This week the U-S-D-A announced that tests seem to indicate a third case of Mad Cow disease in the U.S., and Iowa Senator Tom Harkin says it’s clear the agency must do more to demonstrate it’s following a “clear protocol” for its Mad Cow testing program. “The sample in question was collected in April, yet the USDA just found out about it last week,” Harkin says. “USDA must ensure that there’s adequate education and training for veterinarians so they know what is expected of them out in the field, especially since the USDA’s surveillance plan is totally voluntary.” Harkin has talked personally with U.S. Ag Secretary Mike Johanns and written Johanns a letter, urging the USDA improve its testing so there aren’t delays like this in the future. The latest suspect animal, which died giving birth, was reportedly 12 years old.
