LONDON (Reuters) - Celebrity British chef Gordon Ramsay said restaurants should be fined if they serve out-of-season fruit and vegetables.

"I don't want to see asparagus in the middle of December. I don't want to see strawberries from Kenya in the middle of March. I want to see it home-grown," he said after raising his concerns with Prime Minister Gordon Brown.

"Fruit and veg should be seasonal. Chefs should be fined if they don't have ingredients in season on their menu," he told the BBC on Friday.

Ramsay, whose London restaurants include Petrus and The Savoy Grill, said Britain had become a nation of lazy eaters who followed trends and fads rather than substance.

"There should be stringent laws, licensing laws, to make sure produce is only used in season and season only," he added.
