Weed responsible for hallucinogenic spinach recall identified as thornapple

The scientific name is Datura stramonium. It is also known as jimsonweed.

Authorities said the recalled spinach products had caused delirium and hallucinations. More than 160 people suffered symptoms, with many seeking medical treatment. The recall was initially focused in New South Wales.

Eating the plant can cause: thirst, dilated pupils, high temperatures, weak or rapid pulse, incoherence or hallucinations, vomiting, breathing problems and convulsions, the DPI states. Touching the plant can cause dermatitis, nausea and headaches in some people.

Shoppers over the past week were urged to check and dump any recalled products, including salad and stir-fry mixes, that had been sold at Woolworths, Coles, Aldi and Costco supermarkets.

It is believed the weeds were harvested alongside the baby spinach and processed as such.
