“…In contrast, a higher contamination rate of S. aureus was found in raw goat milk, tank milk, and workers' samples than that in other processing sites. This was confirmed in previous reports (Bianchi et al, 2014;Intrakamhaeng, Komutarin Schlegelova et al, 2010;Spanu et al, 2013). Our results indicated that S. aureus was common in different goat milk powder processing plants.…”

“…For example Türkyilmaz et al (2010) reported that 16 of the 93 S. aureus isolated from bovine mastitic milk were resistant to methicillin. Also in a study by Itrakamhaeng et al (2012), it was discovered that 4 of the 375 S. aureus from bovine mastitis cases were methicillin resistant. Similar report was observed in Nigeria by Suleiman et al (2012) pathogens in bovine mastitis, a disease that causes significant economical losses in the milk industry; thus, S. aureus in general and MRSA in particular have been the focus of several studies in dairy cattle.…”

A study was conducted to determine the prevalence and antibiotic resistance of methicillin resistant Staphylococcus aureus (MRSA) from bovine mastitis in settled Fulani herds in Kaduna state. Three hundred and sixty milk samples randomly collected from selected herds in Kaduna South, Igabi, Lere, Sabon-Gari, Giwa and Zaria were examined. The prevalence of mastitis at cow level was 26.9%, out of which 3.1% and 23.9% were clinical and subclinical mastitis, respectively. The prevalence of both S. aureus and MRSA were 15.3% and 7.8 % respectively. Significant proportion (42.9%) of the MRSA were isolated from cases of mastitis (P<0.05). Very high percentages of MRSA were resistance to penicillin (100.0%), amoxicillin (89.3%), ampicillin (89.3%), tetracycline (85.7%) and erythromycin (71.1%). The multiple drug resistance indices of the MRSA strains revealed that all the MRSA strains were resistant to 5 or more antibiotics tested; 6 (21.4%) strains were resistant to 6 antibiotics, 6 (21.4%) were resistant to 7 antibiotics, 8 (28.6%) were resistant 8 antibiotics and 4 (14.3%) were resistant to 9 antibiotics, while 19 (67.9%) exhibited the extensive drug classification pattern. The MIC values of the antibiotics showed that all (100%) have values greater than 256 μg/mL against oxacillin while 15 (53.6%) have values greater than 256 μg/mL against vancomycin, respectively. Nineteen (67.9%) of the MRSA isolates tested for PBP2a gave strongly positive (3+ to 4+) reactions in the Latex Agglutination Test, 5 (1.9%) were weakly positive (1+) in the Latex Agglutination Test while 4 (14.3%) were negative. The occurrence of MRSA in bovine mastitis is of public health concern due to difficulty in treatment of staphylococcal diseases and possible transmission of resistant pathogens to humans. Therefore, continuous monitoring and surveillance of antibiotic resistance pathogens, good husbandry practices, culling of infected cows and pasteurization of milk to eliminate MRSA and other pathogens are recommended

“…In a survey conducted in Thailand in 2010, Intrakamhaeng et al (2012) found 74 MRSA strains by examining 375 S. aureus isolates collected from 598 mastitis cases, 376 bulk tank milk samples and 46 pasteurized milk samples.…”

Staphylococcus aureus is an opportunistic Gram positive pathogen and the causative agent of many human and animal diseases. It is also an important human foodborne pathogen. Certain strains of S. aureus can produce staphylococcal enterotoxins (SEs) in foods and cause staphylococcal food poisonings (SFP). In recent years S. aureus has been increasingly associated with antibiotic resistance. Methicillin-resistant S. aureus (MRSA) includes those strains that have acquired genes conferring resistance to methicillin and essentially all other beta lactamantibiotics. MRSA was initially reported as a nosocomial pathogen in human hospitals (or hospital-associated MRSA, HA-MRSA). Since the 1990s, community-acquired or community-associated MRSA (CA-MRSA) infections have also been reported to affect people having no epidemiological connection with hospitals. More recently, MRSA has been isolated from most food-producing animals and foods of animal origin, raising public health concerns. MRSA strains have been isolated from cows’ or small ruminants’ milk and various dairy products in many countries. The MRSA prevalence in milk and dairy products recorded in different countries or even regions of the same country differs significantly.High MRSA prevalence have been recorded in milk produced in most African countries, for instance as high as 60.3% in Ethiopia. The MRSA prevalence in Asian countries varies from high e.g. 28.3% in Iran to low (e.g. in Korea and Japan). In most European countries, the MRSA prevalence in milk and dairy products has been generally found to be low. In the US and Canada, zero to low MRSA prevalence estimates have been reported. The investigation of MRSA prevalence in milk may serve as a tool for assessing both the sanitary conditions employed in dairyherds and the health risks that humans may encounter when infected with antibiotic-resistant strains.
