You still get bugs in produce. Always wash produce. Broccoli can have silkworms hiding in the bulbs - especially organic or homegrown, which is difficult or impossible to clean in that case. I personally don’t buy organic broccoli because of that.
But he’s talking about finding worms in fish. Of all the food to be served with worms in it, fish is the most horrifying IMO. I hope they were dead at least.
