This study was performed to evaluate the microbial contamination level of meat processing in butcher`s shops in Seoul from January to November in 2010. A total of 695 samples (112 cotton work gloves, 342 utensils and equipments, 241 meat samples) were collected and the environmental hygiene of 89 butcher`s shops was investigated. The aerobic plate count (APC), E. coli and pathogenic bacteria such as Staphylococcus aureus, Salmonella spp. were tested in the samples. As a result, the level of count on APC ranged 0∼2.2×106 CFU/cm2 from the utensils & equipments, 1×102∼2.7×108 CFU/ glove from the cotton work gloves and 1×102∼9.3×106 CFU/g from the meat samples. The level of count on E. coli ranged 0∼2.5×103 CFU/cm2 from the utensils, 0∼8.6×104 CFU/glove from the cotton work gloves and 0∼1.4×105 CFU/g from the meat samples, respectively. Staphylococcus aureus and Salmonella spp. were detected in 11 samples and 2 samples from the cotton work gloves, utensils & equipments, respectively. The sanitation standard operating procedure (SSOP) was applicated at 49 butcher`s shops. In order to improve sanitation of meat in butcher`s shops, in this study, applications of SSOP, systemic sanitation education for employees, hygenic control of utensils & equipments, and continuous monitoring for microorganisms will be required.

In this study, we compared nutrient content emphasized on labelling of processed milks with that of whole milks and evaluated how well they conform to labelling standard. A total of 98 samples (33 whole milks, 28 calcium fortified milks, 30 low-fat milks and 7 lactose hydrolyzed milks) were collected in hypermarkets in Seoul from August 28 to August 30 in 2012. Calcium, fat and lactose contents were tested in the samples. Calcium contents ranged 102.2∼113.0 mg/100 mL in whole milks and 120.1∼337.8 mg/100 mL in calcium fortified milks. The level of calcium contents in fortified milks ranged very broad. Accordingly, the standard of calcium contents on fortified milks will be required. Fat contents ranged 3.1∼3.9 g/100 mL in whole milks and 0.1∼1.9 g/100 mL in low-fat milks. The average of fats content in low-fat milks was nearly one third than whole milks. Lactose contents was ranged 4.6∼5.1 g/100 mL in whole milks and not detected in lactose hydrolyzed milks. All of processed milks were suitable to processing standard and labelling standard. But nutrition claims often used on processed milk such as High or Low were not adequate to indicate the exact nutrient content, which is a cause of the confusion for milk product labelling to consumers. We need a lot of research about nutrient labelling that can deliver appropriate and understandable information to customers.

Neospora caninum is now recognized as one of the important causes of abortion in cattle worldwide, but there was no report on seroprevalence of antibodies to N. caninum in cattle at Seoul slaughtering center. Serum samples from 610 Korean indigenous cattle (Hanwoo) and 246 Holstein cattle from 452 farms located all over the country, Korea, were tested for N. caninum antibodies using a commercial enzyme-linked immunosorbent assay (ELISA) kit. Seven of 610 (1.1%) Hanwoo and 54 of 246 (22.0%) Holstein cattle were seropositive.
