Found an interesting article on Grist
on the use of arsenic in chicken feed passing through to eggs. This story features two children who had arsenic in their urine that was traced to their backyard chickens. Word to the wise: Arsenic is not allowed in organic feed."The Utah Department of Health
tracked worrisome levels of arsenic in two kids' urine to the family's backyard
No one has
apparently ever checked to see how much arsenic from chicken feed might end up
in eggs, whether those from battery hens or the seemingly wholesome kind children
gather from their backyard birds. The IATP only tested muscle tissue and liver."
It makes you kinda wonder about the presence of arsenic is other animal feeds too. And the composted manure from inorganically raised livestock as well.
