Here, we report the poisoning case of 10 cows. Several distinct clinical signs such as convulsion, excessive salivation, circling, lateral recumbency, and death were observed. Necropsy and histopathological examination did not reveal any significant abnormal findings. Moreover, no bacteria or viruses were detected in tissue, blood, and feeding food. However, endosulfan was detected from the stomach contents and microbials. Our results strongly suggest that death of cows may be closely associated with endosulfan poisoning.

It was aimed to elucidate the underlying mechanism which is elevated the systemic arterial blood pressure by cadmium(Cd). By using the isolated vas deferens and tail artery from Cd-poisoned rats, it was undertaken to see whether the ${\alpha}-adrenoceptor$ activity and prostaglandins action on the twitch response to electrical stimulation were altered. It was discussed in relation with sympathetic nerve activity. The response to electrical stimulation in vas deferens from Cd-poisoned rats was much enhanced, and frequency 50(Freq.50) was significantly lowered, comparing to control. However, the response of rat tail artery was attenuated by Cd. Inhibitory action of clonidine on the twitch response of vas deferens to electrical stimulation was decreased by Cd-poisoning. However, the increase in response in the presence of methoxamine was not affected. The inhibitory action of prostaglandin $E_2$ on the twitch response in the vas deferens but not in the tail artery was abolished or rather inverted by Cd-poisoning. In the tail artery from Cd-poisoned rats, the maximum contraction to methoxamine or clonidine was significantly decreased, however, $ED_{50}$ of both agonists was not changed. These results suggest that in vas deferens the autoreceptor of presynaptic membrane is inhibited by Cd-poisoning, by which mechanism the sympathetic activity is being enhanced and this alteration may be causally related to the elevation of arterial pressure.

Microbial distribution as well as content of salt and preservatives in side dishes was investigated by analyzing cell count of viable cells, coliform bacteria and food poisoning bacteria of sliced squid bokum and anchovy bokum, purchased at 17 different department stores and 2 different traditional market in Seoul, which are most preferred by many consumers to any other side dishes available in the market. 6.2$\times$103~1.2$\times$108 cells/g of viable cell was detected in 19 different samples of the sliced squid bokum, among which samples of the sliced squid bokum and 14 samples of the anchovy bokum contained 103~108 cells/g of coliform group. However food poisoning bacteria were not detected in all the samples tested. Salt content was 2.42~4.89 %w/w and 2.28~6.46 w/w for the sliced squid bokum and the anchovy bokum respectively. Analysis of preservatives by HPLC such as sorbic acid, benzoic acid, dehydroacetic acid and another 6 kinds of esters resulted that 1.0$\times$73.8 mg/100 g of sorbic acid was detected in the 19 samples of the sliced squid bokum, while only 6 samples of the 15 anchovy bokum samples contained sorbic acid.

This paper studies regarding the problems of transmitting disease through food and its prevention in terms of current problematic food poisoning and the transfer of bacterial disease while providing lunch for school children. As the problems of school lunch program, the number of food poisoning and of the transfer of bacterial disease is highly increasing because of the shortcomings of systematic safety management toward food and of the lack of meal supplier's awareness about sanitation.For the prevention the following suggestions are provided:1. It is necessary to shift from the system of meal supply for nutrition to that of meal supply for health. 2. A system that offers a responsibility for nutrition to that of meal supply to a person in charge of hygienist, or a cook, including the a nutritionist, is needed. 3. It is necessary to gain the help from the department of sanitation in city or country for the sanitation guidance and inspection of school meal supply, not to totally rely on the local ministry of education. 4. A manager or employees related to school/group meal supply need to get education constantly on sanitation and public information. 5. For the long term, a systematic sanitary management needs to be accomplished by introducing HACCP system.

The purpose of this study was to examine the attitude toward food safety and the HACCP of college students in Daejeon. 51.9% of respondents had experienced food poisoning. The main symptoms of food poisoning were diarrhea(73.4%), stomachache(57.3%), and vomiting(24.7%). Most students answered that food hygiene was important and more students in private residences recognized the importance of food hygiene than in non-private residences (p<0.05). More information about hygine was obtained from TV & radio(44.9%) than the internet(38.1%). Half of them were afraid of food safety and more females felt unsafe about food sold than males(p<0.01). 37.6% of them were aware of HACCP, more females(44.6%) than males(28.4%) had such knowledge(p<0.001). The more information they had on HACCP, the higher the perception of the HACCP mark(p<0.001). 45.4% of them had seen HACCP mark on food packages and more females had seen it than males(p<0.001), 64% of them purchased HACCP products, The more information they had on HACCP, the more experience they had with HACCP consumption(p<0.001), 44% of them were willing to buy HACCP products. Males(32.3%) wanted to buy HACCP products for their health and females(49.6%) wanted to buy HACCP products if they were the same price (p<0.001). Education about food hygiene and HACCP should be conducted for collage students' health though TV, radio, and the internet.

In this study, toxin gene and antibiotic resistance of food poisoning strains isolated from indoor air in the cafeteria were analyzed to prevent food poisoning. Staphylococcus aureus (16 strains) and Bacillus cereus (37 strains) isolated from indoor air in child care center were tested. The toxin genes of S. aureus and B. cereus were detected by PCR assay. The antimicrobial susceptibility test followed the disc diffusion method described by the Clinical and Laboratory Standard Institute. The seg and sei toxin genes were detected in 11 of 16 S. aureus strains (68.6%). The nheA and nheB toxin genes were detected in 37 B. cereus strains. In this study, a total of 12 toxin gene patterns of B. cereus were found, among which the nheA-nheB-nheC toxin gene was found to be the most frequent pattern. The result of the antimicrobial susceptibility test of S. aureus revealed 93.8% and 87.5% resistance to ampicillin and penicillin antibiotics, but methicillin resistance S. aureus and vancomycin resistance S. aureus were not detected. All 37 B. cereus tested in this study were resistant to ampicillin and penicillin antibiotics. Based on the result of this study, it was judged that regular ventilation and air quality management were necessary to prevent food poisoning caused by S. aureus and B. cereus contaminated in the indoor air of child care centers.

Paralytic shellfish poisoning (PSP) occurs when saxitoxin (STX), which is produced by harmful algae (dinoflagellates) and then accumulated in bivalve shellfish by filter-feeding, is consumed by humans. With recent advances in analysis technology, it has been reported that dinoflagellates also produce a variety of analogues such as the gonyautoxin (GTX) group and the N-sulfo-carbamoyl toxin (C toxin) group, in addition to STX. Accordingly, CODEX and the EFSA are stepping forward to manage STX and analogues as STX groups requiring safety management. In Korea, the occurrence of dinoflagellates producing STX analogues has already been reported, and contamination of analogues (GTX group, C toxin group) in live mussels has also been reported. In this study, in order to provide the basis for systematic monitoring and safety management of STX and analogues, their physicochemical characteristics, occurrence of dinoflagellates, toxicity and toxic equivalency factor, analytical method and occurrence were widely reviewed. This review is expected to contribute to strengthening the safety management of STX and its analogues.

There was an outbreak of food poisoning due to eating well-cooked imported tropical fish, Stromateus stellatus on May, 2000, in Korea. Gastrointestinal symptoms such as diarrhea ($92\%$), nausea ($77\%$), abdominal pain ($54\%$), vomiting ($46\%$) and headache ($23\%$) were experienced within $0.5\~2$ hours (median 1 hour) after eating, Any specific natural toxins were not confirmed concerned to those poisoning, but large amount of abnormal lipid ($23\%$) was found from the muscle such as 1-O-diacyl glyceryl ethers (DAGE), which was consisted of $61.8\%$ of total lipid. The 16:0 ($66.3\%$) and 18:1 ($15.8\%$) alkyl chains were dominant in all alkyl chains of DAGE which were presumed as the causative agent for the diarrheal food poisoning. O1eic acid (18:1) was found as a major fatty acid at the sn-2 or 3 in DAGEs. O-16:0-18:1-18:1 ($16.2\%$),O-16:0-18:1-22:1 ($14.7\%$) and O-18:0-18:1-22:1 ($11.0\%$) were contained as the major molecular species of DAGEs by RI-HPLC.

Vibrio cholerae non-O1 and Vibrio mimicus, food poisoning bacteria, have detected frequently in fresh water and brackish water. To estabilsh prevention measures of food poisoning outbreak by these bacteria, the adaptability and population changes were examined in fresh water, brackish water $(10\%o\;NaCl)$ and seawater $(30\%o\;NaCl)$. Both species poorly survived as temperature increased regardless of water types employed. However, survival time was the shortest in fresh water and longest in seawater at $4^{\circ}C$. In case of brackish water, the bacteria survived best at $15^{\circ}C$ and population were varied only in small numbers. Any significant difference was not observed to both species with respect to water types and temperatures except V. mimicus survived about 5-6 days longer in brackish water. In conclusion, V. cholerae non-O1 and V. mimicus were not likely to be recovered In normal fresh water, brackish water and seawater, and both biological and physicochemical factors could affect survival of these species.
