  • Anisakiasis is a well-known zoonosis caused by ingestion of raw or thermally undercooked seafood product contaminated with live Anisakis nematode third stage larvae (L3). Several traditional processing techniques have been used to kill or remove the Anisakis larvae worldwide, but thermal processing or deep freezing are the most effective treatments to kill the Anisakis larvae. In this study, we investigated the survival of Anisakis larvae in several condiments (soy bean sauce, wasabi, vinegar, red pepper paste) commonly consumed when eating raw fish in Korea. We also examined several different media (NaCl solution, absolute alcohol, soju) to investigate their larvicidal effect. When directly exposed to various condiments, the most effective larvicidal effect was observed in the mixture of wasabi and soy bean sauce. When exposed to different NaCl solutions, the larvicidal ability became more effective as the concentration increased, but did not show 100% killing effect. In soju, the L3 were killed under less than 4 hr. We observed the larvicidal effects of several condiments in this study, but these results are thought to be carefully interpreted for actual use because all the condiments in this study showed the effect in hours and in general, the L3 are exposed to these condiments only for seconds before ingested in real situation.

  • This study was performed to examine antimicrobial resistance of Enterococcus spp. strains from retail raw meat and fish products purchased in 2012. 43 Enterococcus spp. strains were isolated from a total of 207 samples (beef, pork, chicken, fish) with contamination rate of 20.8%. The isolated strains were identified as E. faecalis (22 strains), E. gallinarum, E. hirae (5 strains), E. avium (4 strains), E. faecium (3 strains), E. duram, E. casseliflavus (2 strains). Susceptibility to 10 antibiotics was tested, and the highest resistance was observed to tetracycline. And antimicrobial resistance rates were presented below 20% with most of the other antimicrobial agents. The isolated Enterococci from chicken showed higher resistance also to ciprofloxacin and erythromycin, not only to tetracycline, compared to the isolated Enterococci from beef, pork and fish. Sixteen isolates (37.2%) were sensitive to all antibiotics. Four isolates (9.3%) were resistant to 3 or more antibiotics. Vancomycin-resistant enterococci (VRE) was not identified. According to the results of genetic similarity pattern analysis via PFGE and rep-PCR, Enterococci strains showed different patterns from these collected in 2011. This indicates that there is no genetic similarity among all the strains.

  • The Gwugonsiuebang is a book of Korean woman's life in the Yi dynasty which published I 1653 by Mme. Jang. I have studied the food habits of the Yi dynasty that wrote in Gwugonsiueband as following. The staple foods are Guksu (wheat vemicell as like western noodles) 5, Mandu (bun stuffed with seasoned meat and vegetables) 6 kinds in this book. the side dishes are Guk (soup) 8, J'm (steamed meat or fish) 6, chae6, Nooruemi 5, Hyae (sliced raw fish) 3, Jockpyun (jellied beef soup) 3, Jockgall (salted sea food) 2, Jock (skewer or broach) 2, jihee 2, Sun (Steaming of stuffed vegetable) 1, Bockuem (saute) 1, Jon (pan fried fish) 1, Gui (meat or fish grilled with seasoning) 1, and the other 13 kinds. The desserts are D,ock (Korean rice cake) 11, jabgwa 8, Beverages 5 kinds and Jungwa 1 kind. The alcohol and fruits wine are 51 kinds. The alcohol and fruits wine are 51 kinds. The seasonings are Soybean sauce, oil, Sesamol oil, pepper, Ginger, Garlic, Vinegar, Wine, Salt, Bean paste etc. Raw materials of Guksu, Mandu, D'ock, Jabgwa, Beverage, Wine, vinegar are all carbohydrates. It shows that a tendency of Korean people too much take a carbohydrates. Now and then, there are no special difference of winter over pass for vegetables, fruits, dried beef, dried fish and salt fishes. In yi dynasty, there are 62 kinds of table ware and cooking kitchen utensils, but many of them come to uselessness. 19 kinds of measuring unit are very non-scientific because that is not by weight but by bulk or volume. There are many food making terms which are 198 kinds of prepared cooking term, 11 kinds of cutting term and 20 kinds of boiling term. And 10 kinds of expression of taste can see this book.

  • This study was conducted to investigate the nutritional characteristics of the following Korean-distributed fish species commonly consumed as sliced raw fish (CC-SRF): olive flounder Paralichthys olivaceus (OF), red sea bream Pagrus major (RS), Atlantic salmon (AS), coho salmon (CS) and sockeye salmon (SS). The crude protein and lipid contents of OF, RS, AS, CS and SS were 20.2% and 5.5%, 21.2% and 6.8%, 17.7% and 18.5%, 18.3% and 16.1%, and 20.4% and 5.7%, respectively. Regardless of the type and weight of fish species, the major amino acids were leucine, lysine, aspartic acid, and glutamic acid, whereas histidine was identified as a limiting amino acid. The major minerals in all CC-SRF were P, K and Se based on the recommended daily intake or sufficient intake for Korean males aged between 19-49 years. Among the different types of all CC-SRF, the intake of OF and SS lipids is predicted to be associated with a lower n-6/n-3 fatty acid ratio, whereas among the free amino acids, which are expected to have health functionality, we identified taurine in OF and RS, and anserine in salmons. The digestibility of OF, RS, AS, CS and SS were 60.7%, 54.9%, 48.5%, 49.6%, and 53.4%, respectively.

  • This experiment was conducted to evaluate the long term effects of dehulled soybean meal (DHSM) as fish meal (FM) replacer in the diet for olive flounder, Paralichthys olivaceus, for 42 wk at a commercial fish farm. The four experimental diets were MP (moist pellet based on raw fish), $DHSM_0$ (fish meal based dry pellet), $DHSM_{30}$ (30% fish meal was replaced by DHSM) and COMD (commercial dry pellet). Fish were fed one of the four diets containing 50% crude protein and 16.7 kJ available energy/kg diet for 42 wk. Fish averaging $3.20{\pm}0.04g$ ($mean{\pm}SD$) were initially distributed to each tank as a group of 6,000 fish reared in a flow-through system. At the end of the experiment, average body weight of fish was $315{\pm}9.3g$ ($mean{\pm}SD$) ). Weight gain (WG) and feed efficiency (FE) of fish fed MP, DHSM0 and DHSM30 showed no significant difference among the diet treatments. However, WG and FE of fish fed MP were significantly higher than those of fish fed COMD (p<0.05). Specific growth rate (SGR), protein efficiency ratio (PER) and survival of fish fed all diets were not significantly different among the dietary treatments. Therefore, these results indicate that DHSM could replace up to 30% white fish meal with amino acid supplementation in olive flounder diets for long-term feeding practice at the commercial farm.

  • This study was conducted to investigate the effect of extruded pellets (EP) containing different levels of protein (51%-55%) and lipid (9%-15%) on flesh quality of flounder (Paralichthys olivaceus) comparing with raw fish-based moist pellet (MP). Two replicate groups of 40 fish per each tank (initial mean weight 106 g) were fed one of three experimental EP (EP1, EP2 and EP3) containing different protein and lipid levels, a commercial EP (EP4) and MP for 16 weeks. Moisture content of fish fed MP was significantly higher than that of fish fed all EP. Significantly higher contents of 16:1n-7, 20:4n-6, 20:5n-3 and lower 18:2n-6 were observed in fish fed EP4 and MP compared with fish fed EP1, EP2, EP3. The 22:6n-3 content was not significantly different among all groups. Taurine content of fish fed MP was significantly higher than that of fish fed all EP. Asparagine content of fish fed EP1 was significantly higher than that of fish fed EP2, EP, EP4 and MP. Significant difference were observed in lysine and serine contents of fish fed experimental diets. In nucleotides and their related compounds, ATP and AMP content was not affected by diets. Significant difference were observed in IMP contents of fish fed experimental diets. Textural properties, no significant difference was observed among the fish groups fed different diets.

  • We experienced one rare case of Diphyllobothrium latum infection in childhood. It was proved by collection of worm after praziquantel treatment. Human diphyllobothriasis is chiefly caused through eating raw or unproperly cooked fish such as trout or salmon. This case was a 5-year old girl residing in Seoul, from whom a kind of pseudophyllidean tapeworm was detected in the feces. She would often eat sushi(raw fish) and had abdominal pain, but not revealed any sign of anemia. Obtained chain of worm segments that sized $0.25{\times}1.25cm$ was compatible with D. latum. Including the present 31 cases, total number of human D. latum infections proven by worms in Korea becomes 32 cases, and total number of child D. latum infections proven by worms in Korea becomes 4 cases.

  • This examination was carried out to evaluate the sanitary quality of slices of raw fish being served in the restaurants. Twenty five kinds of slices of raw fish collected from various restaurants in Busan Korea were examined during the period from March to May in 1971. As the evaluation factors of sanitary quality, the contents of sanitary indicative bacteria such as coliform group, fecal coliform, feral streptococci and enterococci and plate counts were determined. The results obtained are as in below: 1. The numbers of fecal streptococci and enterococci MPN were much greater than those of coliform group and fecal coliform. 2. The median value of coliform group MPN was 3,300 per 100 grams of the sample examined and those of enterococci was 5,400. The median value of plate counts was $1.8\times10^5$ per gram. 3. Fifty-two percent of the samples examined were exceeded fecal coliform MPN 930 per 100 grams. 4. As a sanitary indicative bacteria fecal coliform MPN was more reasonable than enterococci 5. The grade of restaurants was not correlated with the bacterial quality of the foods served. 6. No correlation between the numbers of sanitary indicative bacteria ana plate counts was observed.

  • Purpose: The purpose of this study was to describe the prevalence of clonorchiais and analyze the knowledge level and intention of the participants to change their behavior related to clonorchiais. Method: The participants were 514 people from 7 community health posts along the Geum River. The formalin-esther sedimentation technique was used to detect the Clonorchis Sinensis (CS) eggs and a questionnaire for data on related factors. The study was carried on from December 2008 to January 2009. Results: The prevalence of CS averaged 9.3%, with a range from 0% to 24.6%. The significant factors were sex, habit of eating raw fish, and habit related to smoking and alcohol consumption. The level of knowledge was not high and not significantly different between the CS positive group and CS negative group. Intention to change their habits of eating raw fish showed various stages of change and attitudes to raw fish eating habit of others were not positive. Conclusions: These results suggest that a CS control program needs to be developed by community health services in the Geum River area to decrease the prevalence of clonorchiais.
