More than 50 middle school students in Oregon were fed pretzels that were seasoned with crushed oven cleaner last fall, according to a newly filed lawsuit.
About 37 pretzels coated with Alto-Cham concentrated oven cleaner — an industrial-strength caustic chemical made with sodium hydroxide — were served during sixth-grade lunch at Fowler Middle School in Tigard, a suburb of Portland, on October 20, 2025, according to a nearly $1 million lawsuit filed last month.
