I pay tribute to all those working in our food sector, including in manufacturing, who have worked very hard to keep food on our plates during these difficult times. The hon. Gentleman makes an important point. We have heard now of three outbreaks linked to meat plants. They have been picked up through the testing and tracing approach that has been adopted and we are reviewing the guidance. We suspect that these outbreaks might have been linked either to canteens or, potentially, to car-sharing arrangements in those plants. We will be revising guidance to ensure that businesses have the approach that they need to prevent further outbreaks in future.
