I bring you good news about bad gluten. None of it made it to food for people.
The contaminated Chinese wheat gluten was used only in pet food
The contaminant was melamine. Melamine is made by combining urea and formaldehyde under heat and pressure.
Yeah... we eat off that stuff. Well, kinda. The gluten was contaminated with melamine monomer
. We eat off melamine polymer
. Don't you feel better now?
FYI: more on melamine
