“We will not be importing chlorinated chicken. We will not be importing hormone-treated beef. Both of those are illegal under EU law, which we are importing into our domestic system,” said Villiers in an interview with BBC Countryfile to be broadcast later this month.
She added: “There are legal barriers to their import and those are going to stay in place.”
In future trade talks with the US, the UK would “defend our national interests and our values, including our high standards of animal welfare”, Villiers said. “It’s in our manifesto, we have a commitment from the prime minister on this.”
