Speaking on Radio 4's Farming Today programme, Professor Pattison said that he had a grandson, aged three months, who has yet to eat beef.
"My daughter and son-in-law are simply going to wait another six or 12 months to see what happens before introducing him to beef or any beef products," he said.
As for his grand-daughter, aged nine months, "Our son and daughter- in-law have actually given our grand-daughter some beef. They actually prepare the babies' meals from the same material that they use for their own meals - that is , from quality beef" from a well-known high-street supermarket."
The professor was criticised by Labour for spreading further confusion.Reuse content
