Polycyclic aromatic hydrocarbons(PAHs) vary in their carcinogenic potencies. The more potent PAHs carcinogens are 3-methylcholantheren and 7, 12- dimethyl benzo(a)anthracene, while dibenzo(a, c)anthracene has very little carcinogenic activity. Risk assessment of chemical mixture containing various congeners which toxic potency are each different, are conducted using toxic equivalency factors(TEFs).(omitted)

3-Monochloro-1 ,2-propanediol (3-MCPD) produced during the acid hydrolysis of vegetable proteins (ex. soybean products) is food-contaminant material detected in acid-hydrolysed soy, bread, water, et al. 3-MCPD is currently being a matter of concern to safety. The nephrotoxicity of 3-MCPD and 3-MCPD metabolites has been reported to result from accumulating of metabolites in kidney tubules and inhibiting of renal metabolism of glucose and lactate.

This study was performed to evaluate antimicrobial resistance of food-borne pathogens isolated from retail meat in Korea. A total of 157 samples of beef, pork, and chicken were collected and analyzed for E. coli, Salmonella, Campylobacter. Resistances to tetracycline were declined in accord with reduced usage of tetracycline in live stock production. E. coli stains from chicken meat had higher multi-drug resistance ratio than strains from other meat. One extended spectrum beta lactamase (ESBL) producing E. coli and two ESBL producing Salmonella were identified in this study. ESBL producing Salmonella strains were confirmed to carry CTX-M-1 type genes.

This study was performed to investigate the inhibitory activity of ethanol extract from Ecklonia cava (EE-EC) against trypsin and the stability of this activity under various heat and pH conditions. As a results, The EE-EC showed trypsin inhibitory activity of 77, 54, and 32% at concentrations of 5, 2.5, and 1 mg/mL and was not affected by the heat treatment conditions used in this study. Whereas trypsin inhibitory activity of EE-EC was stable in the pH range of 2-8, but decreased with pH treatment of pH 10 compared with the control. Therefore, the EE-EC could be useful as a natural and functional agent.

Recently, many cases related to viral gastroenteritis outbreaks have been reported all over the world. Noroviruses are found to be leading as the major cause of outbreaks of acute gastroenteritis. Patients with acute gastroenteritis are normally found to be positive with norovirus when the stools and vomit are analyzed. This paper reviews various activities and previous reports that describe norovirus contamination in various food matrixes and the relationship between food handlers. Lately, a numbers of norovirus outbreaks have been reported that are involved with fresh produce (such as vegetables, fruits), shellfish, and prepared food. Food produce processed by infected food handlers may therefore become easily contaminated. In addition, foods that required much handling and had been eaten without heat treatment gave the high risk for getting foodborne illnesses. The standard method for detection of norovirus has already been available for stool samples. However, only a few methods for detection of norovirus in food samples have been developed until now.
