 There's a parasitic worm and fish called anisoccus. This year we learned that about two-thirds of retail fish samples came up positive for them. This is what they look like. They're really quite small, actually. You can see two here kind of peeking out of some sushi. Because people eat fish raw, parasites are always a concern. But the unique thing about these worms is that our bodies can be so sensitive to them that the worms can trigger an allergic reaction dead or alive, even if they're cooked. So we're finding some people that are allergic to fish really aren't. They're allergic to the dead worms in the fish. In fact, because we feed so much fish meal to chickens, you can have an allergic reaction to a parasitic fish worm and not even eat fish at all.
