Lettuce sold at Coles and Woolworths in their pre-packaged salad mixes has been voluntarily recalled from supermarkets throughout Australia (excluding Tasmania and Western Australia), after a higher-than-usual number of salmonella cases were reported in Victoria. Grown by Tripod Farmers, the lettuce has been linked to over 100 salmonella cases so far, with two people having been hospitalised. The outbreak may have been caused by a fertiliser sourced from chickens, and its symptoms include fever, loss of appetite, headache, stomach cramps and diarrhoea, amongst others.
