Former Defra Secretary George Eustice has raised concerns about potential post-Brexit trade deals with Canada and Mexico, warning they could lead to imports of pork and beef with low welfare standards. The prospect of such deals has sparked fears of a split within the Conservative Party and the possibility of a revolt. Animal welfare campaigners have criticized the practices used for pigs in Canada and the animal welfare laws in Mexico. Despite these concerns, the government has emphasized that it will not compromise on high food safety and animal welfare standards in trade negotiations.
