Subject: Cooked Fungicides (Was: An instincto's comments)
Hi Wes ,
Thanks for the quoting below. It shows that pesticides are not destroyed by
cooking as most people believe. I knew organochlorines wouldn't, but I
didn't know the fate of organophosphates. They are not destroyed at all by
cooking, but rather concentrated and sometimes broken down into more
dangerous compounds!
Where are you? In New-Zealand?
Thanks also to Jean-Claude for translating "buckwheat"in French.
