Potato mop-top virus (PMTV) has been detected in potatoes purchased from retail outlets in Tasmania. Biosecurity Tasmania is tracing the potatoes back to their production sites, though no confirmed link to previously identified infected farms has been established.
The virus was first identified in July at a farm in Tasmania's north-west, marking the first detection of PMTV in Australia. Since then, the number of sites has increased to eight, including six production farms, one research site, and one storage facility. Biosecurity Tasmania confirmed three additional potatoes tested positive this week.
PMTV does not affect human health but reduces yields and can cause visible defects, such as rust-coloured arcs or streaks in the flesh and distortion of the skin.
In response, Victoria, New South Wales, and South Australia have introduced restrictions on potato imports from Tasmania. Victoria has implemented a 12-month ban on potatoes from Tasmanian farms linked to PMTV. Potatoes from unaffected sites may still be exported if they meet quality requirements. New South Wales and South Australia have also placed import restrictions.
The Tasmanian government has asked the Commonwealth to provide an assistance package for affected farmers.
