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.


The article didn’t seem to say if it was put on before or after baking, but it seems that they probably had the crushed stuff in a plastic bag that looked like salt next to the oven for the pretzels, which would normally come frozen with a little bag of coarse salt. So I wouldn’t really blame the sub worker here, the problem was having the unlabeled cleaner sitting out.
I wouldn’t blame her either, since she wasn’t the one who did it.
