Bisphenol A (BPA) is widely used in the production of polycarbonate plastics, epoxy resins, and food and beverage containers. In the present study, we aimed to investigate the relationship between urinary concentrations of BPA and waist circumference in Korean adults. A total of 1,030 Korean adults (mean age, 44.3 ± 14.6 years) were enrolled in the study on the integrated exposure to hazardous materials for safety control, conducted by the Ministry of Food and Drug Safety from 2010 to 2012. Abdominal obesity was defined as having a waist circumference of at least 90 cm and 85 cm for men and women, respectively. The participants were divided into 4 groups according to the urinary BPA concentration quartile. Waist circumference was significantly higher among subjects with a urinary BPA concentration in the highest quartile relative to those in the lowest quartile (p = 0.0071). Linear regression analysis revealed a significant positive association between urinary BPA concentrations and body mass index, body fat, after adjusting for potential confounders. Moreover, subjects with urinary BPA concentrations in the fourth quartile were more likely to be obese compared to those with urinary BPA concentrations in the first quartile (odds ratio, 1.938; 95% CI: 1.314~2.857; p for trend = 0.0106). These findings provide evidence for a positive association between urinary BPA concentration and waist circumference in Korean adults.
The aim of study was to investigate the correlation between the level of 17
antibiotic residues and 6 antibiotic resistances of Escherichia
coli isolates in chicken meats. A total of 58 chicken meats were
collected from retail grocery stores in five provinces in Korea. The total
detection rate of antibiotic residues was 45% (26 out of 58). Ten out of 17
antibiotics were detected in chicken meats. None of the antibiotics exceeded the
maximum residue level (MRLs) in chicken established by the Ministry of Food and
Drug Safety (MFDS). The most detected antibiotics were amoxicillin (15.5%),
followed by enrofloxacin (12.1%) and sulfamethoxazole (10.3%). In a total of 58
chicken meats, 51 E. coli strains were isolated. E.
coli isolates showed the highest resistance to ampicillin (75%),
followed by tetracycline (69%), ciprofloxacin (65%), trimethoprim/
sulfamethoxazole (41%), ceftiofur (22%), and amoxicillin/clavulanic acid (12%).
The results of study showed basic information on relationship between antibiotic
residue and resistance for 6 compounds in 13 chicken samples. Further
investigation on the antibiotic resistance patterns of various bacteria species
is needed to improve food safety.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
