Airport controls on passengers arriving in the UK remain lax, a survey shows, giving rise to fears among farmers that the country could again fall victim to foot and mouth disease. A survey of 10,000 passengers carried out by the UK's National Farmers' Union indicates that only 4% of travellers were given information about bans on importing meat products. It is widely thought that illegal meat imports were responsible for last year's outbreak of foot and mouth disease, which saw millions of animals culled and cost the UK economy billions of pounds.
