Summary

Data obtained during this study support the opinion that coliforms are still a valid indicator of postprocessing contamination in yogurt. Moreover, the presence of coliforms indicates postprocessing contamination, because they are unable to survive the heat treatments applied during yogurt manufacture. The same is not true for enterococci, which are more heat resistant than coliforms unless higher pasteurization temperatures (above 80 deg C for 10 seconds) are used during yogurt processing.
