“…Also, lower occurrence was observed by[21] who isolated NTS from 3% (4 out of 133) of raw market milk samples but they failed to isolate Salmonella from milk samples collected directly from teat of lactating cows. On the other hand,[22] estimated higher occurrence (20.5%) of NTS in raw milk collected directly from the mammary gland during milking than in our study. Omar, et al[23] illustrated that high presence of Salmonella among raw milk may be attributed to shedding of Salmonella into milk from the infected udder or contamination of raw milk with feces during its collection.…”

The purpose of this study was to investigate the occurrence of non-typhoidal Salmonella (NTS) and the distributed serotypes in New Valley and Assiut provinces. Eight hundred samples were collected (280 from New Valley and 520 from Assiut) from different sources including fecal swabs (160), raw milk (80), Damietta cheese (80), Kareish cheese (80), ice cream (80), yoghurt (80), stool samples (170) and hand swabs (70). Samples were bacteriologically examined then the recovered isolates were serotyped. In New Valley province, occurrence of NTS was 8.57%, 3.33%, 0.00%, 20,00%, 17.14% and 5.71% of milk, Kareish cheese, Damietta cheese, yoghurt, fecal swabs and stool samples, respectively, while, the occurrence of NTS in Assiut was 15.56%, 18.00%, 12.50%, 4.44, 8.75%, 15.56%, 11.43% and 8.00% of milk, Kareish cheese, Damietta cheese, yoghurt, ice cream, fecal swabs, hand swabs and stool samples, respectively. 13 different serotypes were detected in the recovered isolates (87) including S. Typhymurium and S. Enteritidis were the predominant serotypes with an occurrence rate of 24.14% and 20.69%, respectively, followed by S. Tsieve (12.64%), S. Infantis (8.05%), S. Larochelle (9.20%), S. Virchow (5.75%), S. Molade (8.05%), S. Haifa (3.45%), S. Shubra (1.15%), S. Alfort (1.15%), S. Essen (2.30%), S. Apeyeme (1.15%) and S. Heidelberg (2.30%). In conclusion, the high prevalence of the NTS in various dairy products represents an alarm for the public health because of the possibility of transmitting these serovars to consumers, which requires reviewing the methods of control and prevention.

“…However, a previous study in Ethiopia demonstrated that the most common serovar were S. dublin and S. Virchow [ 21 ]. Additionally, S. newport and S. typhimurium were the most predominant in Colombia by (60.87%) and (17.4%) respectively [ 22 ].…”

Background Non-typhoidal Salmonella (NTS) is a major foodborne zoonotic pathogen worldwide. In the current study, Various NTS strains were isolated from (cows, milk and dairy products in addition to humans) in New Valley and Assiut Governorate, Egypt. NTS were firstly serotyped and tested by antibiotic sensitivity test. Secondly, some virulence genes and Antibiotic resistance genes have been identified by using PCR. Finally, Phylogenesis was performed depending on the invA gene, for two S. typhimurium isolates (one of animal origin and the other of human origin for evaluating zoonotic potential). Results Out of 800 examined samples, the total number of isolates was 87 (10.88%), which were classified into 13 serotypes, with the most prevalent being S. Typhimurium and S. enteritidis. Both bovine and human isolates showed the highest resistance to clindamycin and streptomycin, with 90.80% of the tested isolates exhibiting MDR. The occurrence of the invA gene was 100%, while 72.22%, 30.56%, and 94.44% of the examined strains were positive for stn, spvC, and hilA genes, respectively. Additionally, blaOXA-2 was detected in 16.67% (6/ 36) of the tested isolates, while blaCMY-1 was detected in 30.56% (11of 36) of the tested isolates. Phylogenesis revealed a high degree of similarity between the two isolates. Conclusions The high occurrence of MDR strains of NTS in both human and animal samples with high degree of genetic similarity, shows that cows, milk and milk product may be a valuable source of human infection with NTS and interfere with treatment procedures.

“…Salmonella spp. may be excreted directly in the milk by an infected animal [103]. E. coli is a normal inhabitant of the intestines of animals and humans but its recovery from food may be of public health concern due to the possible presence of enteropathogenic and/or toxigenic strains which lead to sever gastrointestinal disturbance [104].…”

Goat milk has medicinal value for children and contributes much more for the wellbeing of human baby. Goat milk provides more nutritional value than dairy cow’s milk. Despite the large number of goats and their contributions to the livelihood of the farmers, goat productivity is low due to prevalence of different diseases. One of the major diseases that affect the dairy goats is mastitis. Mastitis is an inflammation of the mammary gland, caused by over 150 different contagious or environmental micro‑organisms. Mastitis in goats constitutes an enormous animal health problem. In addition to causing health problems, inflammation of the mammary glands can also cause poor quality of milk. Milk produced by goats with mastitis presents a serious risk in terms of public health as it can be linked to milk-borne diseases for humans. Raw milk from Mastitis infected goat is usually colonized by a variety of many zoonotic pathogens such as enterohaemorragic Escherichia coli, Salmonella typhimurium, Listeria monocytogenes and Staphylococcus aureus, Brucella melitensis, Mycobacterium bovis. These pathogens in milk have been linked to mastitis milk. These zoonotic organisms may lead to health problems in the human population such as tuberculosis (TB), brucellosis, haemorrhagic enteritis, salmonellosis and food poisoning. Transmission of pathogens from animals to humans can occur via consumption of milk, especially when these products are consumed raw.
