Senator HANSON (Queensland—Leader of Pauline Hanson's One Nation) (14:33): My question is to the Minister representing the Minister for Agriculture, Fisheries and Forestry, Senator McCarthy. A few years ago sheep farmers had limited access to an Australian manufactured footrot vaccine, called Custom R-Pilus, that was highly effective in reducing and managing footrot, but its use was discontinued by the APVMA. It was also cheaper and much more effective than the single overseas manufactured vaccine now available to Australian farmers to manage this debilitating disease which costs the industry more than $83 million a year. Will the minister please explain why the Australian manufactured vaccine is no longer available to Australian sheep farmers?
