The Dutch farm ministry sealed off more livestock farms on Thursday after discovering cancer-causing dioxin in animal feed that had also been exported to neighboring Germany and Belgium, authorities said. A total of 162 Dutch cattle, pig, sheep and goat farms, eight Belgian farms and three German had bought a potato feed product that was contaminated with dioxin. Authorities in the three countries have temporarily shut all the farms as a precaution since Wednesday and have been examining the feed, the animals and any impact on the food chain. The product was from the Dutch unit of privately held Canadian potato chip maker McCain, the Dutch ministry said.
