This is that same problem the FDA has been ignoring for 2 decades. It is caused by common manufacturing processes, and is a problem in absolutely everything from soda, foods, athletes foot spray, to medications. They seem to pick one product groups to make a big deal about every few years and ignore the others. This is the limited hangout style slow-roll by the FDA, to limit alarm that we're being absolutely poisoned by everything sold to us. Last, before this, was all aerosol foot sprays and deodorants.
