Staphylococcus aureus and Escherichia coli in nham (Thai-style fermented pork sausage).
The fate of Staphylococcus aureus and Escherichia coli was determined when they were introduced into ground pork made into nham (Thai-style fermented pork sausage) with or without 0.75 or 1.5% added starter culture. Without starter culture, the numbers of E. coli remained little changed but there was slow multiplication of S. aureus. With 0.75% starter culture, S. aureus was no longer detectable after 48 h and E. coli numbers decreased by 1 log after 96 h. No viable S. aureus or E. coli were recovered after 36 h and 96 h, respectively, when 1.5% starter culture was added. The addition of a starter culture is recommended when making nham.
