“…When nasal swab culture was examined, S. aureus was found in (54.95%) and coagulase negative staphylococcus was in (5.41%). The prevalence of nasal staphylococci carrier in this study is higher than that in the study [24] in Brazil (40.8%) and in Iraq (30.1%) [17]. In the study in Spain, 27.6% of 300 food handlers were found to be nasal coagulase positive staphylococci carriers [25].…”

“…(56.9%) of the nail cultures, and another study where the presence of S. aureus on hands of the food handlers in schools expressed (53.3%) [3,16]. In contrast, other studies who reported lower S. aureus prevalence are (30.1%) [17], (29.2%) [18], (23.5%) in Ethiopia [12], (17.5%) in Makkah, Saudi Arabia [19], (16.5%) from their nger-nail contents [20], (12.6%) isolated from hands of Iranian food handlers [21], (11.1%) [22] and (5.6%) [23]. This difference in contamination may be due to different populations and areas of the study.…”

Background: Microbial contamination of food can occur from contaminated or infected food handlers.Methods: This study aimed to assess type of bacteria and their antibiotic sensitivity pattern of nasal and hand swab samples from food handlers working in hospital compounds, Mandalay city, Myanmar. All eligible food handlers working in the government hospital compound, Mandalay City, Myanmar, were subjected to a cross-sectional study conducted from May to August 2018. Hand and nasal swabs were collected from of food handlers for bacterial isolation and identification. Antibiotic sensitivity patterns of isolated bacteria were determined.Results: Among 111 participants, 92 (82.9%) were bacteria-positive by hand swabs and 77(69.37%) were positive by nasal swab. Among Staphylococcus aureus isolated from nasal swabs, just over a half (51.2%) were resistant to oxacillin (probably methicillin resistant Staphylococcus aureus). There were association between hand contamination and nasal bacterial growth (p<0.001).Conclusion: Bacterial contamination status of the food handler working in hospital compound, Mandalay city, Myanmar, was extremely high.

“…The presence of S. aureus on the workers' hands have been explained by the fact that the primary habitat of this bacteria is nasal cavity and that it can be resident or transient from normal microbiota, causing no symptoms to humans (Accoa, Ferreira, Henriquesa, & Tondo, ). Approximately between 11 and 40% of healthy individuals have S. aureus , while others are occasionally colonized (Alhashimi, Ahmed, & Mustafa, ; Castro, Santos, Meireles, & Teixeira, ; Forsythe, ; van Belkum et al, ).…”

This study evaluated microbial contamination and good manufacturing practices (GMP) in school kitchens. Thus, the kitchen of four municipal schools have been assessed through microbiological analysis performed in their cutting boards (n = 12), kitchen sinks (n = 12), dish cloths (n = 12), hands of food handlers (n = 22), kitchen sponges (n = 12), milk (n = 10), and water (n = 10). A questionnaire was also applied to food handlers in order to access their profiles and get to know their daily practices inside school kitchens. The results this study showed that all samples (surfaces, cutting boards, kitchen sponges, milk, and water) were contaminated with heterotrophic bacteria. Staphylococcus aureus was found on the surface of sinks, dish cloths, cutting boards, and on the hands of food handlers. Fecal coliforms were found on sinks, water, and milk. Results from the survey reveal that food handlers know about GMP, but they do not perform these activities in school kitchens. Practical applications The presented study shows that the schools there are failures in good manufacturing practices (GMP), which increase the risks of food contamination. In addition, we also showed microbial contamination on surface, cutting boards, kitchen sponges, and in food (milk and water) on schools which it make a risk for the development of foodborne diseases, since children have a relatively lower immunity than adults, additional safety measures are needed to protect them from foodborne pathogens and high microbial contamination in school. The microbial contamination in schools show that although the food handlers know about GMP, but there is a necessity for correct surface cleaning in food preparation to avoid foodborne illnesses proliferation in schools

“…Another study was done in Tikrit, Iraq by Alsamarai et al, (2015) who found that 28% (n=100) of studied food handlers were carrier for S. aureus. Alhashimi et al, (2017) revealed that the prevalence of nasal carriage of S. aureus among 332 food handles in Karbala city, Iraq was 30.1%. A further study was done in Turkey; in which S. aureus was lower than that of the current study 20% (Vatansever et al, 2016).…”

“…Staphylococcus aureus is a common commensal of the skin and mucosal membranes of humans, with estimates of 20-30% for persistent and 60% for intermittent asymptomatic carriers. The presence of these bacteria in food occurs frequently due to inappropriate manipulation of food by carriers (Alhashimi et al, 2017). Globally, foodborne diseases are one of the main health problems and the World Health Organization (WHO) estimated that they caused 600 million foodborne illnesses and 420,000 deaths in 2010.…”

Food handlers harbouring S. aureus on their noses or in hands are considered as the main source of food contamination. Antibiotic resistance in S. aureus is a serious issue. The study aimed to find out the prevalence of methicillin-resistant S. aureus among food handlers in restaurants of Duhok city. Nasal and hand swabs were taken from 200 food handlers. The collected swabs inoculated on mannitol salt agar and incubated at 37oC for 24-48h. Isolates identified as S. aureus underwent antimicrobial sensitivity testing to methicillin and vancomycin on Mueller Hinton agar. A total of 74 (37%) out of 200 cultures of food handlers were found to be colonized with S. aureus.53 (26.5%) isolated from the nose, compared with 8 (4.0%) from hands and 13 (6.5%) from both. 27% of the food handlers were found to be MRSA carrier, and none of the isolates were resistant to Vancomycin. The study revealed a high prevalence of MRSA among food handlers in Duhok city. Food handlers in public places are required to go through regular screening for both nasal and skin carriage of S. aureusfor the early detection and treatment of carriers. So as to protect the community from staphylococcal food poisoning and the spread of resistant S. aureus strains among the population.
