Hort Innovation: A new levy-funded resource produced by AHR looks at the risks of redback spider contamination of broccoli and offers risk management strategies. Since 2016 there have been numerous customer complaints about redback spiders (Latrodectus hasselti) in broccoli. Complaints have mainly come between January and June, and from customers in all Australian states. This suggests that this is not an issue for a single production area, but can occur anywhere that broccoli is grown.
