How are viruses and parasites different from bacteria in terms of food safety?. scientific literature related to emerging microbiological food safety issues.

Most familiar bacteria, like Escherichia coli, staphylococci, and Salmonella spp. are neutrophiles and do not fare well in the acidic pH of the stomach. However, there are pathogenic strains of E. coli, S. typhi, and other species of intestinal pathogens that are much more resistant to stomach acid.

As mentioned above, some bacteria, such as Streptococcus bovis, produce a strong acid called lactic acid. Megasphaera elsdenii uses lactic acid to grow. This helps to clean up the rumen a bit and raise rumen pH, aiding the growth of the acid-intolerant fiber-digesters.
