Emergency workers who responded to the scene of a three-train crash last week in Northwest Indiana wound up getting sick hours after they left the scene, but it wasn't from anything on the trains.
Health officials think it may have been the food they were given by the Red Cross while on the scene.
A Porter County Health Department spokeswoman says they're looking into the complaints, according to the Sun-Times.
At first, they started looking at what was aboard the trains to find a cause, but the investigation turned to the other common denominator - the food everyone ate.
Three trains collided just northeast of Valparaiso on Friday. The cars were carrying a wide variety of freight, including chemicals. Liquids spilled and a subsequent fire forced people in the area to evacuate their homes.
Officials said about 20 people became sick of the more than 300 workers who were on the scene.
The Red Cross is referring all questions to the health department.
