The studies have not looked closely enough to know if it happens with seedless yet. It happens with raisins, grapes, and currants. The mycotoxin hypothesis never panned out; neither did any fungicides, herbicides, or pesticides. That doesn't mean that one might not have been missed, of course. Mycotoxins are often neurotoxic and that isn't happening, either, BTW, from what I've read. Having an item, in this case grapeseed, impair platelet aggregation is a serious concern -- heck, a counter-indication -- if a bleeding disorder is present, which it was with these ferrets. If they were clotting too much then that could be a different matter perhaps, but they were not. They were bleeding. You don't give something that could impair the body's own natural ways to reduce bleeding during a bleeding disorder.
