Mycotoxins in Cured Meat

Mould growth and mycotoxin production are related but not identical. A mould can be non-toxigenic, conditionally toxigenic or produce toxin only under particular environmental conditions.

Contaminated spices, feed-derived carryover and unwanted Penicillium or Aspergillus growth can contribute. In dry-cured meats, ochratoxin A is a major subject of monitoring and research.

Temperature, humidity, water activity, oxygen, surface nutrients and competition influence growth and toxin formation. A late correction may stop growth without removing existing toxin.

Defined food-grade surface cultures can occupy the niche and support predictable ripening, but strain identity and process conditions still matter.

Surface swabs, mould identification and toxin analysis answer different questions. Sampling must represent location, depth, batch and the decision being made.

Control raw materials, spices, chamber hygiene, cultures and environmental conditions. Suspect product requires competent evaluation; washing, smoking or trimming is not a universal corrective action.
