While authorities are still investigating the source of the listeria-tainted cantaloupe outbreak that killed 25 people and sickened more than 100 others, the FDA now believes that puddled water and dirty packing equipment is the likely culprit.
From the Associated Press:
The FDA said Jensen Farms had recently purchased used equipment that was corroded and hard to clean. The agency said the way the cantaloupes were cooled after coming off the fields may have also contributed to listeria growth.
