What happens to probiotic bacteria in ice cream?
Counts of probiotic bacteria were found to be much higher in enriched ice cream than in control samples, reported the researchers. No significant reduction in bacteria was observed after freezing and during the storage period, indicating that the storage temperature of minus 20°C did not negatively affect survival of probiotic microorganisms.
How often is Salmonella found in ice cream?
The agency detected Salmonella in one of the 89 ice cream production facilities (an establishment-based prevalence of 1.1%), and in one of the 7,004 subsamples (a subsample-based prevalence of 0.01%).
