William Bethel Jr., 24, had car problems, so he borrowed the wagon from a friend's mortuary transport service in Philadelphia to deliver pizzas.
He admitted he shouldn't have been driving at all since his license was under suspension, but said he was desperate for money.
His Ford Mustang was in the shop, the ceiling at his row house needed repairs, and he had a wife and two young kids to support.
Police stopped Bethel for an expired inspection sticker and impounded the Buick.
"No one wanted to go near the food because they were concerned about possible contamination," Lower Southampton Police Lt. Raymond Weldie said.
But both the state and Bucks County health departments said there is no law against delivering a body and food in the same vehicle.
Chris Ryder, a spokesman for the state Department of Agriculture, said as long as the pizzas and bodies stay in their "separate containers" there isn't really a food safety concern.
