Illegal hot dog vans in Olympic crackdown London organisers LOCOG has already unveiled its "food vision" for the event, which it described as "the largest peace-tome catering operation in the world." LOCOG has pledged to use high-quality, sustainable, organic and British food wherever possible. It has signed deals with 12 different catering contractors for the games, including McDonald's, which is another likely reason why the authorities are keen to keep unwanted vendors away from official Olympic venues. A spokesman for the FSA said that the three van pounds are located in East London, West London and "south of London." The spokesman said that the mobile vans could be "any type of non-fixed businesses, such as ice-cream vans and hot dog stalls." We are concerned that if they don't meet hygiene standards, they will simply move to trade in another area. It's better if we can take this equipment off the streets to help protect the public," the spokesman said. He added that the geographical spread of the compounds will help local authorities to "avoid having to travel across the city to find storage space." "We very much hope that they won't have to be used," the spokesman said.
