A fast-growing cyclosporiasis outbreak has put lettuce, salad greens and select Taco Bell ingredients under scrutiny as thousands of Americans report a parasite-linked illness known for causing severe watery diarrhoea.

However, public health officials have not confirmed a link to Taco Bell, any specific restaurant, ingredient, supplier or retailer.
