A study identified the consumption of ground beef prepared from neck trimmings processed at a single slaughtering plant as the cause of an outbreak of thyrotoxicosis in adjacent areas of Minnesota, South Dakota, and Iowa between April 1984 and August 1985. Bovine thryoid tissue (BTT) was found in samples of the trimmings, and high thyroid hormone levels were found in samples of the ground beef produced by the plant. The procedure introducing BTT into neck trimmings has since been discontinued by the plant. The results indicate that consumption of the beef produced elevated serum thyroid hormone levels in consumers.(wz)
