Over 1000 samples have been collected and 78 greenhouses in South Australia have been tested for tomato brown rugose fruit virus (ToBRFV) after the virus was detected at two properties in the Northern Adelaide Plains region. The virus has prompted interstate and international border control measures, including the suspension of tomato imports to New Zealand. The source of the outbreak is under investigation, with speculation it may have come in via contaminated seed. The Australian Seed Federation is willing to collaborate with DAFF to protect Australia's biosecurity while maintaining access to high-quality seed for growers.
