abstract="Approximately 30 sixth-grade students from an Acadia Parish school developed a gastrointestinal illness shortly after eating lunch on September 8, 1975. The suspected vehicle was orange drink that had been stored in the school's milk shake machine. Designed only for handling dairy products but modified to dispense carbonated beverages, the machine had a mixing chamber consisting of 60% copper alloy. Subsequent chemical analysis of orange drink before and after  carbonization in the mixing chamber established copper contamination.",
