A study examined the effect of reducing sodium chloride (NaCl) levels in frankfurters on the degree of microbiological growth of 2 bacterial species. Frankfurters with 60-100% of the normal level of 2.5% of NaCl, 150 ppm of sodium nitrite, and 430 ppm of vitamin C added were incubated with S. aureus or C. sporogenes at 11 degrees C for 11 days. Frankfurters treated with the lowest level of NaCl showed a slightly more rapid growth of natural flora, but no growth related to salt level was noted for either of the test microorganisms. Use of higher incubation temperatures indicated that storage temperature had a greater effect on growth of the test bacteria than NaCl levels. (wz)
