I am surprised there is zero audit trail for a good purchased at Whole Foods to be honest.

City water in Flint was poisonous, buying drinking water from a respectable retailer should not be risky.

If you sent a a sample to a water testing company, would they have detected the hydrazine, it’s not like it’s a common contaminant and I’m sure it’s is very small quantities which while still harmful are why it wasn’t obvious??
