Clostridium botulinum bacteria may be of concern in raw and cooked refrigerated meat products with a shelf-life greater than 10 days, for which strict cold-chain management cannot be guaranteed. This case study describes the testing of a new proprietary clean-label system from Kerry Taste & Nutrition, Rosal XB, for the inhibition of C. botulinum spore germination in a number of cooked poultry products. Products were inoculated with non-proteolytic strains of C. botulinum under modified atmosphere packaging (MAP) conditions. They were stored under simulated cold-chain conditions and assayed for C. botulinum growth at appropriate intervals. Research results demonstrated that under the test conditions, products can achieve a shelf-life of 25 days, without the risk of C. botulinum growth.
