“…On the other hand, 7 brand milk samples were tested out of which 3 samples were positive for S. aureus, 2 samples were positive for E. coli and no sample was positive for Salmonella typhi, whereas the prevalence of the organisms was 42.86 %, 28.57% and 0%, respectively (Table 3). In this study, the prevalence of Staphylococcus aureus, Escherichia coli and Salmonella typhi in milk samples has received considerable attention which is in support of several scientists (Zecconi and Hahn, 2000;Mrema et al, 2006;Jay, 2000;Watts, 1989;Jones, 1990;Dabassa and Bacha, 2012;Hasan et al, 2015). E. coli may be considered an indicator microorganism of faecal contamination and other enteric pathogens.…”

Cow's milk containing pathogenic bacteria is an important threat to the consumers. The objectives of the present study were to identify the bacterial agents of public health importance in milk samples (n=35) of different locations and to determine their sensitivity to different antibiotics. The milk samples were collected and transported aseptically and subsequently allowed for culture in bacteriological media, Gram's staining and biochemical tests for the identification of bacterial species. The bacteria identified were Staphylococcus aureus, Escherichia coli and Salmonella typhi, and their prevalence, in case of vendor milk specimens (n=28), were 96.43%, 53.57% and 35.71% respectively, and of brand milk specimens (n=7), were 42.86 %, 28.57% and 0%, respectively. This suggests that cautionary measures should be taken for quality milk production and consumption. The antibiotic sensitivity test was done by disc diffusion method and the average inhibition zones, in case of Staphylococcus aureus, were 32 mm for oxytetracycline, 26 mm for amoxicillin, 35 mm for ciprofloxacin, 27 mm for cefotaxime, 30 mm for ceftriaxone, 30 mm for azithromycin, and 26 mm for erythromycin; in case of Escherichia coli, were 5 mm for oxytetracycline, 9 mm for amoxicillin, 22 mm for ciprofloxacin, 30 mm for cefotaxime, 31 mm for ceftriaxone, 15 mm for azithromycin, and 0 mm for erythromycin; in case of Salmonella typhi., were 25 mm for oxytetracycline, 24 mm for amoxicillin, 38 mm for ciprofloxacin, 31 mm for cefotaxime, 34 mm for ceftriaxone, 24 mm for azithromycin, and 0 mm for erythromycin. Therefore, ciprofloxacin and ceftriaxone may be the antibiotics of first choice, and cefotaxime and azithromycin may be the second choice among the test antibiotics for the treatment of illness caused by these bacteria.

“…This level of excretion is maintained for several weeks, before falling gradually until the individual no longer excretes (Taylor & McCoy, 1969). Furthermore, after the disappearance of the organism from the intestinal tract, up to 5 % of patients, upon recovery from this disease, may become carriers who shed the organism in their faeces (Jay, 2000). Therefore, detection of Salmonella strains in faecal samples is not only important for the diagnosis of salmonellosis, but also essential to identify carriers of this organism, especially among food handlers, who have higher risks of spreading the pathogen.…”

“…The optimal temperature for Salmonella growth is 37 • C with a range of 5 to 47 • C, and the optimum pH is 6.5 to 7.0 with a range of 4 to 9 [9][10][11]. Animal feed is a potential source of Salmonella [12][13][14][15][16][17].…”

Various culture-based methods to detect Salmonella in animal feed have been developed due to the impact of this bacterium on public and animal health. For this project, tris phosphate carbonate (TPC) and buffered peptone water (BPW) buffering capacities were compared as pre-enrichment mediums for the detection of Salmonella in feed ingredients. A total of 269 samples were collected from 6 feed mills and mixed with the pre-enrichments; pH was measured before and after a 24 h incubation. Differences were observed when comparing pH values by sample type; DDGS and poultry by-product meal presented lower initial pH values for TPC and BPW compared to the other samples. For both TPC and BPW, meat and bone meal presented higher final pH values, while soybean meal and peanut meal had lower final pH values. Furthermore, for BPW, post cooling, pellet loadout, and wheat middlings reported lower final pH values. Additionally, most feed ingredients presented significant differences in pH change after 24 h of incubation, except DDGS. From meat and bone meal samples, four Salmonella isolates were recovered and identified: three using BPW and one using TPC. TPC provided greater buffer capacity towards neutral pH compared to BPW, but BPW was more effective at recovering Salmonella.
