Federal and state health officials are investigating whether Taco Bell restaurants helped spread one of the largest US outbreaks of cyclosporiasis in years, a parasitic illness causing 'explosive' diarrhoea that has reached 34 states and sickened thousands.
The key detail is that Taco Bell is being investigated, not blamed. Some people who fell ill reported eating at the chain, while others never set foot inside one, telling investigators the outbreak stretches well beyond its kitchens.
