May I join those who have praised Public Health England? Not every hospital involved has necessarily had fatalities or major problems, but it was very important that Public Health England notified all those who might have been supplied by the same people. May I put it to the Secretary of State that we should not just think that there was one cause of listeriosis? It can come from processed vegetables, processed meats, ice cream and other things. May I ask him to recommend to everyone that people try to ensure there is safe handling, safe cooking and safe consumption to reduce the risk of cross-contamination? When an outbreak happens, that is the way, as well as through the work of Public Health England, that people can help to ensure it does not affect them.
