Staphylococcus aureus (S. aureus) can cause mastitis in cattle and, therefore, can be present in milk. This study was undertaken to determine the prevalence of coagulase positive S. aureus and its enterotoxin genes sea, seb, and sec in isolates recovered from raw milk, feta cheese, and human hand swabs of milk and cheese handlers in Beni‐Suef province, Egypt. A total of 100 samples of raw milk and 50 samples of pasteurized‐milk feta cheese were collected. In addition, 50 hand swabs from milk handlers and 25 hand swabs from cheese handlers were examined for the presence of coagulase positive S. aureus. The isolates were characterized by multiplex PCR for detection of sea, seb, and sec genes, and for resistance to 5 classes of commonly used antibiotics. Twelve (12/100), 12 (6/50), and 17% (13/75) of milk, cheese, and hand swab samples, respectively, were positive for coagulase positive S. aureus. One isolate was obtained from each positive sample (31 isolates), and none contained genes for SEA or SEC production. Twenty‐five percent, 33%, and 31%, respectively, of the isolates contained the genes for SEB, resulting in 3%, 4%, and 5% of samples being positive for toxin producing coagulase positive S. aureus, respectively. At least one isolate was resistant to each of the antibiotics tested. Despite the low potential for SEB production shown, preventative measures, such as maintenance of the cold‐chain and good hygienic practices should be implemented to further reduce the potential risk to public health from SEB, and to reduce the spread of antimicrobial resistance.  相似文献

The occurrence of Campylobacter spp. in a variety of foods from Ottawa, Ontario, Canada, and raw milk samples from across Canada was determined over a 2-year period. The samples consisted of 55 raw foods (chicken, pork, and beef), 126 raw milk samples from raw milk cheese manufacturers, and 135 ready-to-eat foods (meat products, salads, and raw milk cheeses). Campylobacter jejuni was detected in 4 of the 316 samples analyzed: 1 raw beef liver sample and 3 raw chicken samples. An isolation rate of 9.7% was observed among the raw chicken samples tested. This study also investigated the role of cross-contamination in disseminating Campylobacter from raw poultry within a food service operation specializing in poultry dishes. Accordingly, kitchen surfaces within a restaurant in Ottawa, Ontario, were sampled between March and August 2001. Tests of the sampling method indicated that as few as 100 Campylobacter cells could be detected if sampling was done within 45 min of inoculation; however, Campylobacter spp. were not detected in 125 swabs of surfaces within the kitchens of this food service operation. Despite the reported high prevalence of Campylobacter spp. in raw poultry, this organism was not detected on surfaces within a kitchen of a restaurant specializing in poultry dishes.  相似文献

Cheese may be manufactured in the United States using raw milk, provided the cheese is aged for at least 60 days at temperatures not less than 35 °F (1.7 °C). There is now increased concern among regulators regarding the safety of raw milk cheese due to the potential ability of foodborne pathogens to survive the manufacturing and aging processes. In this study, 41 raw milk cheeses were obtained from retail specialty shops, farmers’ markets, and on-line sources. The cheeses were then analyzed for the presence of Listeria monocytogenes, Salmonella, Escherichia coli O157:H7, Staphylococcus aureus, and Campylobacter. Aerobic plate counts (APC), coliform and yeast/mold counts were also performed. The results revealed that none of the enteric pathogens were detected in any of the samples tested. Five samples contained coliforms; two of those contained E. coli at less than 102 cfu/g. Three other cheese samples contained S. aureus. The APC and yeast-mold counts were within expected ranges. Based on the results obtained from these 41 raw milk cheeses, the 60-day aging rule for unpasteurized milk cheeses appears adequate for producing microbiologically safe products.  相似文献

The presence of psychrotolerant Bacillus species and related spore formers (e.g., Paenibacillus spp.) in milk has emerged as a key biological obstacle in extending the shelf life of high-temperature, short-time pasteurized fluid milk beyond 14 d. A recently developed rpoB DNA sequence-based subtyping method was applied to characterize spoilage bacteria present in raw milk supplies for 2 processing plants, and to assess transmission of these organisms into pasteurized products. Thirty-nine raw milk samples and 11 pasteurized product samples were collected to represent the processing continuum from incoming truck loads of raw milk to packaged products. Milk samples were held at 6°C for up to 16 d and plated for bacterial enumeration at various times throughout storage. Among the 88 bacterial isolates characterized, a total of 31 rpoB allelic types representing Bacillus and Paenibacillus spp. were identified, including 5 allelic types found in both raw milk and finished product samples. The presence of the same bacterial subtypes in raw and commercially pasteurized milk samples suggests that the raw milk supply represents an important source of these spoilage bacteria. Extension of the shelf life of high-temperature, short-time pasteurized fluid milk products will require elimination of these organisms from milk-processing systems.  相似文献

Analytical tools that accurately predict the performance of raw milk following its manufacture into commercial food products are of economic interest to the dairy industry. To evaluate the ability of currently applied raw milk microbiological tests to predict the quality of commercially pasteurized fluid milk products, samples of raw milk and 2% fat pasteurized milk were obtained from 4 New York State fluid milk processors for a 1-yr period. Raw milk samples were examined using a variety of tests commonly applied to raw milk, including somatic cell count, standard plate count, psychrotrophic bacteria count, ropy milk test, coliform count, preliminary incubation count, laboratory pasteurization count, and spore pasteurization count. Differential and selective media were used to identify groups of bacteria present in raw milk. Pasteurized milk samples were held at 6°C for 21 d and evaluated for standard plate count, coliform count, and sensory quality throughout shelf-life. Bacterial isolates from select raw and pasteurized milk tests were identified using 16S ribosomal DNA sequencing. Linear regression analysis of raw milk test results versus results reflecting pasteurized milk quality consistently showed low R2 values (<0.45); the majority of R2 values were <0.25, indicating small relationship between the results from the raw milk tests and results from tests used to evaluate pasteurized milk quality. Our findings suggest the need for new raw milk tests that measure the specific biological barriers that limit shelf-life and quality of fluid milk products.  相似文献
