Résumé

The authors' objective was to determine if the addition of CO2 influenced the risk of botulism from milk. Carbon dioxide was added to pasteurized 2% fat milk at approximately 0, 9.1, or 18.2 mM. The milk was inoculated with a 10-strain mixture of proteolytic and nonproteolytic Clostridium botulinum spore strains to yield 100 to 1000 spores/millilitre. Milk was stored at 6.1 or 21 °C for 60 or 6 days, respectively, in sealed glass jars or high-density polyethylene plastic bottles. Evolution of milk and growth of Clostridium are studied as well as production of botulinal toxin.
