Mr. Tadhg Gavin:

I will take Deputy Nolan's questions. On use, she answered the question herself. She is correct that every time these products are used, the parasites that are exposed to the products develop resistance. It is the overuse that drives that resistance. As Mr. Geraghty alluded to, these products can be advertised and that is used to promote sale. When the products become prescription only, they cannot be advertised so there will not be a marketing edge to the sale of these products.

On the prescription, that is an act of veterinary medicine and it is not just based on one simple facet but on a three-pronged approach of test data, clinical examination and on-farm risk assessment.

Those three parameters are used to decide whether a prescription is necessary. That is the key. The greatest achievement in this will be if a farmer decides that he or she needs to dose, has a conversation and, ultimately, no prescription is issued. The result will be that a product that needs to be spared is not used on that occasion, and that will be the best outcome.

I might pass to Mr. Geraghty to respond to Deputy Fitzmaurice.
