I cannot take Swedish food with me to the UK You can. There are no additional restrictions on taking food INTO the UK from Sweden.
British food is perfectly safe to eat.
Meat comes only from unaffected areas and is carefully tested to ensure that it is free from foot and mouth. Restaurants are serving British beef, lamb and pork, and people are eating it, without any problems. You can walk anywhere on tarmac roads. Most roads and attractions, including parks, beaches, churches, museums, historic buildings, sporting events, and golf courses, are open as normal. But most of the UK is unaffected, and most visits can go ahead exactly as planned.
