Ketchup: A Fishy History
At the turn of the 20th century, 12 young men sat in the basement of the Department of Agriculture, eating meals with a side of borax, salicylic acid, or formaldehyde. They were called the Poison Squad, and they were part of a government experiment to figure out whether popular food additives were safe. (Spoiler: Many weren’t.) Food manufacturers weren’t pleased with the findings, but one prominent ketchup maker paid attention. Influenced by these experiments, he transformed ketchup into the all-American condiment that we know and love today. Except ketchup—both the sauce and the word—didn't come from the United States. The story of America’s favorite condiment begins in East Asia. Harvey Wiley (back row, third from left) and the members of The Poison Squad.
