Viability of Salmonella in bone meal.
The ability of Salmonella to survive varying concentrations of sodium metabisulphite incorporated into bone meal (rendered animal by-product) was investigated. No viable Salmonella was detected after 4 days of exposure of the micro-organisms to 5,000 ppm of sodium metabisulphite. The minimum killing concentration of metabisulphite was also established at 4,000 ppm. However, the killing effect of the metabisulphite was moisture-dependent, being most potent at a moisture level of 8 to 12%.
