Contaminated food?

Thank a Republican.

From overworked employees not given bathroom breaks?

From industrialization of food products?
"And the fast-food industry's demand for uniform products has encouraged centralization in every agricultural sector. Fruits and vegetables are now being grown, packaged and shipped like industrial commodities. As a result, a little contamination can go a long way. The Taco Bell distribution center in New Jersey now being investigated as a possible source of E. coli supplies more than 1,100 restaurants in the Northeast.

While threats to the food supply have been growing, food-safety regulations have been weakened. Since 2000, the fast-food and meatpacking industries have given about four-fifths of their political donations to Republican candidates for national office. In return, these industries have effectively been given control of the agencies created to regulate them."

From mis-feeding our cattle (thanks to Bryan in comments)?
"Traditionally, all beef was grass-fed beef, but in the United States today what is commercially available is almost all feedlot beef. The reason? It's faster, and so more profitable. Seventy-five years ago, steers were 4 or 5 years old at slaughter. Today, they are 14 or 16 months. You can't take a beef calf from a birth weight of 80 pounds to 1,200 pounds in a little more than a year on grass. It takes enormous quantities of corn, protein supplements, antibiotics and other drugs, including growth hormones.

Switching a cow from grass to grain is so disturbing to the animal's digestive system that it can kill the animal if not done gradually and if the animal is not continually fed antibiotics. These animals are designed to forage, but we make them eat grain, primarily corn, in order to make them as fat as possible as fast as possible."
