In this study, baby formulas, follow-on formulas, cereal-based supplementary foods, fruit purees, vegetable purees, menus and mixtures, rice pudding and milk pudding, snacks, and beverages were investigated to determine the presence of various pathogenic bacteria and their hygienic qualities. The antibiotic resistance of isolates was determined by disc diffusion method. In the samples examined, Enterobacteriaceae, coliform, Bacillus cereus, Staphylococcus aureus, mold, and yeast contamination levels were found to be 42.96%, 0.74%, 2.22%, 0.74%, 23.70%, and 2.96%, respectively. The presence of Pantoea spp. (2.96%), Klebsiella pneumonia (5.19%), Enterobacter cloacae (0.74%), Serratia plymuthica (0.74%), Sphingomonas paucimobilis (0.74%), Bacillus pumilus (0.74%), Staphylococcus hominis (2.96%), Staphylococcus epidermidis (2.96%), Enterococcus casseliflavus (2.96%), and Enterococcus faecium (0.74%) was also found in analyzed samples. Salmonella spp., Listeria monocytogenes, Escherichia coli O157:H7, E. coli, Cronobacter sakazakii, and sulfite-reducing anaerobic bacteria were not found in any sample. Pantoea spp., K. pneumonia, E. cloacae, S. paucimobilis, B. cereus, S. hominis, and S. epidermidis isolates showed multiple resistance to three or more antibiotics. The determination of multiple antibiotic resistance in some isolates with the presence of pathogen and potential pathogenic bacteria was found to be important in terms of public health.
