Aquatic Animal Health and Plant Health (Legislative Functions) (EU Exit) Regulations 2019

My Lords, I thank the Minister for his detailed exposition of the extent of this legislation. It sounds as though the existing regime will transfer without too much of a hiccup in order to enforce the regulations. However, in declaring my interest as a livestock rearer and a farmer, I cannot resist pointing out that the existing system is not totally foolproof. This is really for another day, but we need to realise that certain diseases seem to slip in not just by midges being blown across from Europe. Two that affect sheep in particular which have come in are maedi visna and ovine pulmonary adenocarcinoma—OPA. These diseases are now hidden in our own flocks and are very difficult to determine.
