Fish hatcheries got contaminated feed

Fish feed made with a contaminated Chinese ingredient was distributed to about 120 fish hatcheries and farms, roughly split between the United States and Canada, officials said.

U.S. officials said the risk to people from eating fish that ate the contaminated feed was very low.

The feed, manufactured by Skretting Canada, used imported Chinese wheat flour, purchased from a second Canadian company, that was spiked with melamine and mislabeled as wheat gluten.
