We have no idea how those chemicals mentioned affect us when found in the food chain if at all and they are in it no doubt. I have never knowingly eaten horsemeat but I am certain if hungry enough I would. Regardless of how much of it is in the food chain we do know that people today live longer than they did a few hundred years ago so it may not be all bad. A lot of the so called organic stuff today is a scam, unproductive, and is an excuse to charge more. The rules on what can be labeled organic are not airtight.
