Researchers have developed a two-in-one test that can detect both the E. coli bacteria responsible for food poisoning and the toxins it produces.

In the past, they had to conduct two separate tests that took three to five days.

The new test takes only 24 hours.

The bacteria itself doesn't cause problems. It's the toxins, or poisons, it produces that make people sick. The toxins can remainin the food long after the bacteria are gone.

E. coli O157, a particularly virulent strain, has been linked to foodborne illness outbreaks that involved spinach, ground beef, lettuce and peanut butter, among other food items.
