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.
More than 50 students ate all or part of the impacted pretzels, according to Tigard-Tualatin School District records obtained by Fox 12.


Kids these days are so spoiled with their designer sodium compounds. In my day we seasoned our food with elemental sodium and we were grateful (for a very short period).
The explosion was the best part
It was like PopRocks, but better.
