“…The overall prevalence of 8.7% revealed by this study is lower than the 11.8% reported by Karns et al (2005). However, it is on the higher side when compared with the 2.6% and 0.0% reported by Van Kessel et al (2004) and Mhone et al (2012) respectively. These variations may be explained by the differences in location, hygienic practices and the availability of potable water.…”

This study was conducted to determine the prevalence of Salmonella species in milk and locally processed milk products traded for human consumption and assess the risk factors associated with Salmonella milk contamination in the study area. The study utilized microbiological culture and isolation as well as questionnaire analysis. A total of 600 samples were studied, 200 each for fresh milk (madara), full creamed milk (kindirmo) and skimmed milk (nono). The study revealed an overall prevalence of 8.7% (52/600). About 0.2% (1/600), 3.0% (18/600), 1.0% (6/600), 2.0% (12/600) and 2.5% (15/600) of the overall prevalence were recorded in Dengi, Gargah, Kanam, Gagdi and Gidgid districts of the Local Government Area (LGA) respectively. This revealed a high level of statistical significance (P<0.05). Prevalence rates in relation to milk type were 6.4% (38/600), 1.5% (9/600) and 0.8% (5/600) for fresh milk, full creamed milk and skimmed milk respectively. This showed a high level of statistical significance (P<0.05). Based on sources of water used for milk processing, prevalence rates were 6.8% (41/600), 1.7% (10/600) and 0.2% (1/600) for stream water, well water and borehole water respectively. These differences were highly significant statistically (P<0.05). Risk factors analysis revealed that 31.3% (188/600) of the respondents were not aware of salmonellosis and 82.2% (493/600) were not aware of the risk of acquiring Salmonella via milk consumption. There were high association between the prevalence of Salmonella in milk and the risk of sucking milk directly from the udder of cows (P<0.00001, OR = 8.7448), the use of stream water in processing milk (P=0.0001, OR = 3.6733) and failure to wash the udder of cows before milking (P=0.0041, OR = 0.2072). This study has revealed the presence of Salmonella species in milk traded for human consumption and the risk factors associated with their contamination in Kanam Local Government Area of Plateau State, Nigeria.

“…Different other previous study recorded in Egypt was carried out in 2014, and the results revealed that (12%) of the milk samples were positive for Salmonella species by using the conventional culture methods [20] . On the other hand, the result of the present study is in contrast with the results of the previous studies obtained from [21,22] , who indicated that Salmonella species did not isolate and detect in examining raw milk samples.…”

Two hundred and ten samples were included in this study. The samples encompassing of 90 cattle milk samples obtained from local markets, and 120 stool samples obtained from children with gastroenteritis of age less than 12 years from both genders who were attending to the Babylon maternity and children's hospital. The samples were collected during the interval from February to August 2018 in Babylon province.All these 210 samples were subjected to many tests for isolation and identification of Salmonella species by using bacterial culturing, biochemical tests, and API20E test system. The results showed that the prevalence of identifying Salmonella isolates were 69 (32.9%) out of 210 samples, distributed as (25/90) (27.8%) market milk and (44/120) (36.7%) stool samples. The identified Salmonella isolates were subjected to serotyping by monovalent antisera. It was found that 4 out of 25 isolates (16%) in market milk samples and 16 out of 44 isolates (36.4%) in stool samples that belong to Salmonella infantis. PCR technique was achieved to identify invA and invF virulence genes in Salmonella infantis strains. All 20 isolates of Salmonella infantis in market milk and stool samples were examined. The results revealed that, invA gene was detected in all strains of Salmonella infantis isolated from the market milk and stool samples, while the invF gene was present in 2 strains of the market milk Salmonella infantis, but existing in all strains of the stool Salmonella infantis.

“…The absence of Salmonella enterica in 'brukina' may be attributed to the cold temperature (about 4 o C) they are kept for sale. Mhone et al (2012) examined 120 raw cow milk and 20 processed cow milk from smallholder dairy farms in Zimbabwe and found no Salmonella enterica. Similarly, to this study, Salmonella enterica were not found in 'brukina' but were found in the other samples examined.…”

Salmonella enterica are among the foodborne pathogens of importance due to their involvement in a number of foodborne outbreaks, illnesses and occasionally death. This study was carried out in the Tamale metropolis of Ghana to investigate the prevalence and antibiotic resistance of Salmonella enterica in cow milk, cow milk products and hands of cow milk sellers. The conventional method and the disc diffusion method were used for the isolation and antibiotic resistance of Salmonella enterica, respectively. The overall prevalence of Salmonella enterica was 7.3% (22/300). Salmonella enterica were detected in 24.0% (12/50) of raw 'wagashie', 8.0% (4/50) of fried 'wagashie', 6.0% (3/50) of cow milk, 4.0% (2/50) of left hand swab of milk sellers, and 2.0% (1/50) of right hand swab of milk sellers. Salmonella enterica was not isolated from 'brukina'. The prevalence of Salmonella enterica did not differ (P = 0.193) among fried 'wagashie', cow milk, hand swab of milk sellers and 'brukina' samples. However, the prevalence of Salmonella enterica in raw 'wagashie' was significantly higher (P = 0.000) than the other samples examined. Resistant to erythromycin (86.0%) was most frequently detected. The Salmonella enterica isolates were highly susceptible to ciprofloxacin (100.0%), chloramphenicol (91.0%), ceftriaxone (91.0%), sulphamethoxazole/trimethoprim (91.0%), tetracycline (86.0%) and ampicillin (86.0%). Of the 22 Salmonella enterica isolates, 14 were resistant to only one antibiotic, 4 were resistant to two antibiotics and 2 were resistant to three antibiotics. Two Salmonella enterica isolates were resistant to none of the antibiotics. This study revealed that some milk products and other samples were contaminated with Salmonella enterica. The isolated Salmonella enterica were susceptible to most of the antibiotics examined but were highly resistant to erythromycin.
