Dr. Damien Barrett:

The animals we are most concerned about are breeding animals. This will have no implications for animals that are going for slaughter.

As to the risks in a zero grazing system, if grass is collected from badgers’ toileting areas next to their setts, it is possible that contaminated grass could be carried in. Another aspect of a zero grazing setup is that it will be in a farmyard and there will probably be more than grass being used for feed. Those other feeds will need to be kept bio-secure from badgers because some of them are very palatable to badgers. It is correct to say that zero grazing carries more risks, but they can be managed.
