The horticulture industry in South Australia is on high alert after the detection of the highly contagious tomato brown rugose fruit virus (ToBRFV), prompting concerns about the source of the outbreak and any potential spread. The virus, which poses a significant threat to tomato, capsicum, and chilli crops, leading to yield losses of up to 70%, has raised fears among farmers and industry experts. The virus may have been introduced through imported seed, highlighting the strict regulations around the import of seeds and plant products into Australia. In response, New Zealand has temporarily halted tomato imports from Australia as a precaution. This development unfolds during the inaugural National Biosecurity Week, a nationwide initiative aimed at emphasizing the importance of biosecurity in protecting the environment, food supply, and economy. The week is funded by Plant Health Australia and Animal Health Australia as part of the Decade of Biosecurity initiative, which encourages broad participation in strengthening biosecurity systems. The detection of ToBRFV and the ongoing discussions around biosecurity funding highlight the complex challenges faced in safeguarding Australia's agricultural sector from harmful pests and diseases.
