Cyclospora

The Centers for Disease Control and Prevention estimates that 48 million Americans get sick with a foodborne illness every year. How can this massive number be greatly reduced? By irradiating our food.
E. coli. Salmonella. Campylobacter. Norovirus. When somebody gets sick eating at a restaurant, these are often the culprits. But McDonald's has been hit by an outbreak of Cyclospora. Our PhD microbiologist – who has taken two classes in medical microbiology – had never heard of that. So what is it?
Although threats from Mexican drug cartels cannot be dismissed out of hand, apparently another Mexican import cilantro (also known as coriander or Chinese parsley) has sickened hundreds of Americans in the past couple of years.
Since June, the CDC has been notified of nearly 400 cases of infection by the parasite Cyclospora in seventeen states. At least twenty-two people have been hospitalized because of this outbreak.
