How Listeria Contaminates Cantaloupes and How to Stay Safe

Listeria outbreaks linked to cantaloupes raise concerns about how bacteria enter fruit. The primary route is surface contamination of the rind. When a knife cuts through the melon, it transfers bacteria from the exterior to the edible flesh.

Prevention

• Thoroughly wash the melon under running water and scrub with a clean produce brush before cutting.
• Sanitize cutting surfaces and knives.
• Refrigerate cut melon promptly and consume within a few days.
