Dive Brief:

• Colorado cantaloupe farmers Eric and Ryan Jensen were arrested Thursday in relation to a fatal 2011 listeria outbreak.
• The deadly outbreak killed 33 people, and the brothers received misdemeanor charges of introducing adulterated food into interstate commerce.
• The U.S. Food and Drug Administration and Centers for Disease Control believe the fruit wasn't cleaned properly, likely becoming contaminated in the farm's packing house due to dirty water on a floor and hard-to-clean equipment.

Dive Insight:

The farm's equipment was reportedly old and hard to clean, previously being used to clean potatoes—a possible source of the listeria. A truck hauling the fruit to a cattle operation was also a potential source of contamination.
