Abstract-Throughout the world, food processing and handling is a major problem leading to food poisoning and infection. A total of 480 samples was analyzed for Staphylococcus aureus contamination which resulted from food processing. Most of the isolates were taken from food-handlers using nasal swabs. The most contaminated food was chicken pastries, followed by egg sandwiches and spring rolls. Isolates from all samples produced virulence factors hemolysin, coagulase, DNase and enterotoxins. Five different enterotoxins (SEs) were isolated and identified from different samples. The detected SEs are SEA to SEE. Most the isolates secreted SEA followed by SEB. The strains were multiple-resistant to several antibiotics. Ampicillin and penicillin were the most resisted antibiotics. The value of this investigation is to generate awareness about the dangers of food processing and handling leading to infections by foodborne microbes which constitute a potential health risk for the consumers.Index Terms-Staphylococcus aureus, contamination, food products, food handlers. I. INTRODUCTIONFood processing is an important industry worldwide. One of the major problems threatening food industry is the contamination with foodborne microbes of human origin resulting from improper handling and processing. Microbial contamination reduces shelf life and food quality leading to food infection and poisoning outbreaks, some of which are life threatening. Continuous monitoring of food processing is essential to avoid potential health problems.Staphylococcus aureus is one of the major foodborne pathogens, frequently causing diseases globally as a result of food ingestion contaminated with staphylococcal toxin [1].S. aureus is characterized by its ability to produce enterotoxins [2], which are considered to be the main causative agents of staphylococcal food poisoning [1]. S. aureus are commonly found on the skin of mammals, birds and fomites [2]. Humans are considered to be the major source of staphylococcal food poisoning [3]. S. aureus is found in nasal passages, throat, hair and skin of carriers [2]. Food is usually contaminated from nasal secretions, sneezing, coughing and direct hand contact of infected carriers [4], [5].Three categories of S. aureus carriers have been Manuscript received November 9, 2013; revised February 21, 2014 recognized: persistent, intermittent (occasional) and never-carriers. Persistent carriers are infected with the same staphylococcal strain for months or even years. It was reported that 20% -35% are persistent carriers. In addition, intermittent carriers represent 40% -70%, while never-carriers are uninfected representing 10% -40% of the population [6], [7].S. aureus secretes several virulence factors and extracellular toxins of protein origin which contributes to the pathogenicity. It is the only species that produces beta hemolysin which lyse red blood cells at cold temperature [6].Unlike other foodborne illnesses, staphylococcal food poisoning occurs shortly after, 30 min to 8 hrs, food ingestion contamin...

“…Antibiotics have been broadly used in farm animals for the purpose of antimicrobial therapy, prophylaxis and growth promotion (Mathew et al, 2007;Waters et al, 2011). This increasing handling of antibiotics has led to a worldwide problem in the development of antibiotic resistance among bacterial populations during recent decades (Shryock and Richwine, 2010).…”

This study was conducted during a six months period (March to August 2008) at the Veterinary laboratory, Department of Animal Resources, Doha, Qatar to determine the incidence of different bacterial genera farm animals in particular the occurrence of Staphylococcus species. The samples were from the rectum, milk, feces, nasal, swab of vagina, cloacal -uterin, intestine, liver and pus. Samples were collected from various animals of different regions. A total 318 of 429 samples gave positive results for Gram-negative and Gram-positive bacteria and 90 cultures were identified as Staphylococcus. The highest isolates were from camels' milk and none were obtained from specimens of cats and horses. A total of 33 selected Staphylococcus isolates were identified to species level and the most common isolated was coagulase-positive S. aureus (14), followed by coagulase-negative, S. lentus (10), S. xylosus (5), S. sciuri (2), S. lugdunensis (1) and S. caprae (1). The antimicrobial susceptibility profiles of these were determined using cephalothin, gentamycin, neomycin, ampicillin, norfloxacin, penicillin, tetracycline and a combination of trimethoprim and sulphamethoxazole. All identified species were sensitive to cephalothin except one strain of S. aureus. Most of the isolates showed multiple antimicrobial resistance profiles.
