Gabriella- what I was trying to say is that currently EU rules ensure that wherever goods are made, or produce/meat produced- they have to follow EU regulations and standards, re safety, chemicals, pollutants, etc, etc.
Which is not at all guaranteed after Brexit. Especially if we have to go with begging bowl to these countries for trade agreements. Trump has made that very clear. He wants us to drop our EU based requirements on animal welfare, pollutants and chemicals in produce we buy, be they meat, cereal or other- give up working rights re wages, conditions, hours, holidays, maternity, etc, etc.
