This from the Guardian:

"Tim Lang, emeritus professor of food policy at City, University of London and author of Feeding Britain, said: “Our supply chains are creaking and we are seeing a forerunner of what could be a huge crisis. There has been a total failure by the government to develop a proper food strategy.

He said it is “absurd” to be increasingly relying on fresh produce grown more than 1,000 miles away in places such as north Africa while UK production is being wound down.

It is not just food that is at risk in complex supply chains. Pharmacists, who rely on drugs from China and India, report that some patients are now forced to go from chemist to chemist to try to find one that can fill their prescriptions. There have been shortages of cold and flu medicines, from Lemsip to Night Nurse, over the winter."

Personally, I would point out that shortages of Lemsip, Night Nurse and the like are of no real significance - no one is going to die for the want of Lemsip, FFS. Shortages of some antibiotics are clearly rather more serious, however, so long as there are alternatives, not life threatening but the moment we run out of the full range of broad spectrum antibiotics then people will die as a result!
