Dietary Risk Assessment for Polycyclic Aromatic Hydrocarbons in Foods
Journal of Food Hygiene and Safety, volume 19, issue 1, 2004, Pages 1~8
This study was executed to determine the cumulative dietary risk of PAHs exposed by food ingestion. Food samples including barbecued beef, barbecued pork, grilled chicken, ham, bacon and vegetable oil which were collected from food markets. These samples were saponified, extracted and cleaned up to purify PAHs, and then the purified sample solutions were analyzed by HPLC-FL. Generally, the levels of total PAHs in barbecued beef (0.2 ppb), bacon (0.3 ppb), barbecued pork (0.7 ppb), ham (0.8 ppb), and vegetable oil (1.2 ppb) were low, whereas the level of total PAHs in grilled chicken (9.3 ppb) was significantly high. For the exposure assessment of PAHs due to food ingestion, PAHs levels converted into TEQ
, the average body weight for 20-73 age group and consumed levels of food proposed from report on the National Health and Nutrition Survey were used. The estimated lifetime average daily intake of dietary PAHs was 4.32
kg/day as the mean value. The dietary risk adjusted to cancer potency of benzo(a)pyrene as 7.3 (mg/kg/day)
based on current data.ata.
Safety Evaluation of Lead and Cadmium in Domestic and Imported Kimchi
Journal of Food Hygiene and Safety, volume 19, issue 1, 2004, Pages 9~11
Safety evaluation of lead and cadmium were taken in Kimchi, of which imports is on the increase. The results showed that the levels of lead and cadmium in domestic Kimchi were 0.2964 mg/kg and 0.0637 mg/kg, and the levels in imported Kimchi were 0.3557 mg/kg and 0.0656 mg/kg, respectively; the difference was not significant. Compared with the previous results, the contamination levels of Kimchi, which are composed of various vegetables, were higher than those of vegetables or leafy vegetables. Ingestion levels of heavy metals were lower than the PTWI by mean values or simulation results, but the total safety evaluation must be taken in every food category.
Determination and Survey of Fluoroquinolones Residue in Chicken Muscle by HPLC with Fluorescence Detector
Journal of Food Hygiene and Safety, volume 19, issue 1, 2004, Pages 12~18
Ofloxacin, norfloxacin, ciprofloxacin, and enrofloxacin in chicken muscle were seperated by liquid extraction and determined with high performance liquid chromatography (HPLC) with fluorescence detector. Analysis was carried out using following conditions; Cl8 column (250
4.6 mm i.d. 5
particle size), mobile phase composed of D.W. (containing 0.4% triethylamine and phospholic acid): methanol : acetonitrile (800:100:100, v/v/v), isocratic pump at a flow rate of 1.0
/min and 50
of injection volume, fluorescence detector with EX278 nm/EM.456 nm. The calibration curves of four fluoroquinolones showed linearity (
0.999) at concenration range of 0.025-0.6
/ml. The recoveries in fortified chicken muscle represented more than 80% with low coefficient of variation (〈10%) for concentration range of four fluoroquinolones. The detection limits for ofloxacin, norfloxacin, ciprofloxacin, and enrofloxacin were 23.5, 3.4, 3.0 and 2.5 ng/g in chicken muscle, respectively. We also monitored fluoroquinolones residue in muscle of chickens (broiler 1:227, Korean native chicken 219, laying chicken 77) using EEC-4-plate screening and HPLC conformation methods. Ten(broiler 5, Korean native chicken 5) out of the fifteen samples which were positively detected by EEC-plate screening method from 1,523 chicken meat were confirmed with ciprofloxacin and enrofloxacin by HPLC. The ranges of residual concentration were 0-0.12 ppm for ciprofloxacin and 0.01-6.79 ppm for enrofloxacin. In conclusion, our method could be applied effectively to determine four fluoroquinolones residues in chicken meat, and further survey for fluoroquinolones residue in chicken meat are needed for more effective control of fluoroquinolones used in livestock.
A Review of Dose-response Models in Microbial Risk Assessment
Journal of Food Hygiene and Safety, volume 19, issue 1, 2004, Pages 19~24
Dose-response models in microbial risk assessment can be divided into biologically plausible models and empirical models. Biologically plausible models are formed by the assumptions in dose distribution of microbes, host sensitivity to microbes, and minimal infectious dose of microbes : there are Exponential model and
-Poisson model, representatively. Empirical models are mainly used to express the toxicity of chemicals : there are Weibull-Gamma model etc. Deviance function (Y) is used to fit available data to dose-response models, and some dose-response models for food-borne pathogens are developed in humans and experimental animals.
Comparative Study on Growth of Spoilage Microorganisms in Mungbean and Soybean Sprout
Journal of Food Hygiene and Safety, volume 19, issue 1, 2004, Pages 25~30
This study was conducted to investigate effect of mungbean sprout and soybean sprout against the growth of spoilage microorganism (Bacillus subtilis, Bacillus cereus, Pseudomonas fluorescens, and Listeria monocytogenes). After blanching at different conditions, the viable cells of the spoilage microorganisms were increased with storage time, but the viable cells were almost same after treating with either mungbean sprout or soybean sprout. The viable cell population in minimal broth treated with filtrate of mungbean sprout was higher than that of soybean sprout after 24 hr. However, the growth of spoilage microorganism in filtrate of mungbean sprout and soybean sprout was depending upon strain type. During incubation for 72 hr at
, the color change of mungbean sprout was appeared moderately, but in soybean sprout it was appeared clearly at 24 hr. These results indicate that the effect of mungbean sprout and soybean sprout against growth of spoilage microorganism was not different.
Changes of Components Affecting Organoleptic Quality during the Ripening of Traditional Korean Soybean Paste -Amino Nitrogen, Amino Acids, and Color-
Journal of Food Hygiene and Safety, volume 19, issue 1, 2004, Pages 31~37
This study was performed to investigate the changes of amino nitrogen, total amino acids, free amino acids, and cole. of traditional Korean soybean paste (doen-jang) during the ripening and storage for 12 months. All of the preparation methods for soybean paste followed the recommendations of the Korea Food Research Institute. The components of soybean paste were analyzed at 0, 6, and 12 months. The content of amino nitrogen of soybean paste was significantly higher than that of soybeans or meju (soybean cakes) at the initial stage of storage (p〈0.05), and decreased during the storage. The composition of total and free amino acids and their ratios of soybean paste were changed during the storage. The ratios of free to total amino acids of soybeans, meju, and soybean paste were 0.8%, 17.3%, and 20.4∼32.9%, respectively. Glutamic acid, which represents the savory taste, was detected the most abundantly in soybean paste during the storage. The ratios of free to total amino acids of glutamic acid were 21.1∼41.5% in soybean paste. Lightness, redness and yellowness of Hunter color of soybean paste decreased over time (p〈0.05). The results of this study indicate that the ratios of fee to total amino acids of soybean paste were much higher than those of soybeans, although its contents of total amino acids were much lower than those of soybeans. The results also indicate that this comes from the preparation and fermentation of meju. It was suspected that the organoleptic quality of soybean paste derived from these three components might be inferior over 1 year of storage time.
Studies on the Knowledge, Attitudes, and Behavior of Mothers Toward Food Hygiene and Safety of School Food-Service Programs - part 1
Journal of Food Hygiene and Safety, volume 19, issue 1, 2004, Pages 38~48
This study was performed to investigate knowledge, attitudes and related behavior on the food hygiene and safety management of school food-service programs among mothers and to find factors affecting their knowledge, attitudes and behavior. A self-administered questionnaire was offered to a random sample of 301 mothers who have children attending elementary schools in one region of Korea. The survey was carried out over a two-month period (April-May,2001). They had lower behavior scores compared to the scores of knowledge and attitudes (p〈0.05). The micro levels of the knowledge, attitudes and behavior scores also showed the same tendency. Logistic regression analysis showed that mothers' education level affected their knowledge and attitudes, while the participating activity in school food-service programs affected their behavior the most frequently. Pearson's correlation analysis confirmed that the knowledge and attitude scores were significantly correlated (r=0.61404, p〈0.001). The results indicate that the knowledge and attitude levels of mothers regarding the food hygiene and safety of school food-service programs were good, however, their behavior levels were not satisfactory. The findings highlight the importance of participating programs in school food-service programs to close gaps between the behavior and knowledge or attitudes of mothers and to improve their behavior levels.
Computation of Maximum Edible Time using Monitoring Data of Staphylococcus aureus in Kimbap and Food MicroModel
Journal of Food Hygiene and Safety, volume 19, issue 1, 2004, Pages 49~54
The prevention of infectious disease from contaminated foods is very important in public health. Quantitative microbial risk assessment has been used in advance countries to achieve the safety of public health against hazardous microbial causing contaminated foods. This study was conducted to estimate maximum edible time without producing enterotoxin from Staphylococcus aureus in Kimbap selling at different domestic store using Food MicroModel and monitoring data and to compute maximum edible time by temperature with 99th percentile safety probability based on only restaurant data. For estimating maximum edible time, model operation conditions like reaching time at 2
, which enterotoxin was known as producing point from S. aureus, temperature of 28∼3
, pH 5.2, NaCl 0.22%, aw(water activity) 0.99, and intaking one serving size of 171g in Kimbap were considered. Estimated maximum edible times by regarding outdoor temperature in summer were 3.9∼4.6 hrs in restaurant, 6.7∼7.9 hrs in department store and 7.4∼8.7 hrs in convenient store. Based on restaurant data, estimated maximum edible times with 99th percentile safety probability by temperature were 1.9 hrs in 3
and 17.7 hrs in 15
