The BBC examines food systems continuity in this feature, saying: Half of the food consumed in the UK comes from overseas, official figures show, with 30% coming from the European Union. Some basics like wheat to make flour for bread, or lamb chops, may well have come from the other side of the world.
The good news is that there are plans in place to keep essential supplies flowing. For example, the Freight Transport Association is working hard to ensure that, in the face of a shortage of garage mechanics, trucks still get serviced as and when required.
Meanwhile, the government is treating logistics workers in the same way as the emergency services or NHS staff. So they should have better access to coronavirus testing, and be able to keep their children in school, so that they are free to go to work.
There is also spare capacity that is now free to be used. For instance, the closure of car plants across the country means that their fleets of supply trucks will not be needed for the duration. And the same goes for suppliers to all the restaurants, bars and cafes which have been shut down.
