food poisoning

The U.S. Department of Agriculture announced Tuesday that it's putting an end to a controversial research program that led scientists to kill thousands of cats over decades.

Since 1982 the USDA's Agricultural Research Services division had been conducting experiments that involved infecting cats with toxoplasmosis — a disease usually caused by eating undercooked contaminated meat — in order to study the foodborne illness. Once the cats were infected and the parasite harvested, the felines were put down.

Matt Arteaga, 51, is one of about 500 people who got sick this summer in an outbreak linked to McDonald's salads. The cause was a parasite, cyclospora.

Arteaga fell ill on a Thursday afternoon in June. He was in his office in Danville, Ill., when he says the symptoms came on quickly. "The chills, and body aches, severe cramping, sharp pain in my stomach," Arteaga recalls.

The illnesses started appearing in late March. Here and there, across the country, people were checking themselves in to hospitals, sick from toxic E. coli bacteria. At least 200 people got sick. Five of them died.
