Results: All samples were found to be contaminated with bacteria up to 105
CFU/g and with
the fungal flora within a range of 101
-102
CFU/g. Escherichia coli, Pseudomonas spp. and
Staphylococcus spp. were demonstrated in most of the samples. Sodium sulfite and citric acid
possessed the strongest anti-bacterial trait against all of the test bacteria. Acetic acid exhibited
activity against 6 out of 8 test bacteria while vinegar exhibited the activity against 4 bacteria.
Activity of salt was demonstrated only against Listeria spp. and Bacillus spp., while activity of
sugar and honey was found only against Escherichia coli and Klebsiella spp., respectively.
