Outbreak _ S1 E11 _ Forensic Files _ FULL EPISODE

In 1985, 121 people in South Dakota and Minnesota were struck by a mysterious illness. The victims had alarmingly high levels of thyroid hormones pumping through their systems, but no one could figure out why [citation:4][citation:6][citation:8]. Investigators studied one family where everyone got sick—except their 12-year-old son [citation:1]. The clue: he was a vegetarian [citation:5][citation:10]. The investigation traced the outbreak to ground beef contaminated with animal thyroid tissue [citation:3][citation:5].
