The aim of this study was to determine the prevalence and infection status of Salmonella species (spp.) in 25 conventional pig farms by traditional fecal culture and serological methods to develop a Salmonella control program for Korean pig farms. The individual seroprevalence of Salmonella spp. in pigs reared in the 25 pig farms was 83.1% in sows and 6.4-32% in different aged pig groups, with the total seroprevalence 28.4% (141/848). The seroprevalence of the tested pigs increased in accordance with the decrease in maternal antibody and the rearing period on these farms. Of note, all the 25 pig farms contained at least two or more anti-Salmonella antibody-positive sows. In the fecal cultures Salmonella spp. were isolated only in three (12.0%, 3/25) of 16 serologically Salmonella-suspected farms (64.0%, 16/25), showing the limitation of the fecal culture method and the need for serum assays to understand the exact status of Salmonella infection in swine herds, which likely contain subclinically infected pigs or carriers. The results highlight the need to establish a supply system of Salmonella-free gilts for the promotion of a national Salmonella control program on swine farms in Korea. Further studies will be needed to develop an effective monitoring system for the implementation of a national Salmonella control program.

Surface Plasmon Resonance (SPR) sensor system, has rapid response and high sensitivity, can be applicable for detecting reaction times of many biospecific interactions. A SPR sensor system was constructed to detect the antigen-antibody reactions of salmonella and hIgG (human immunoglobulin G). Sensor chips made of gold thin film were used for detecting biological bindings of antigen and antibody reactions. The antigen and antibody reactions for salmonella and hIgG were carried out with various time intervals to observed characteristics of these reactions using SPR sensor system. The resonance angle shift changes were clearly observed at the time of salmonella or hIgG antibody injection into sample cell since each antibody was self-assembled on gold chip surface of the sensor. It was found that the antibodies of salmonella and hIgG reacted with its sensor chip surface in 10 minutes and 60 minutes respectively. And the antigens of both salmonella and hIgG were bound to its antibody within 1 minute.

This study was conducted to investigate the detection rate and serotypes of Salmonella spp. in conventional and welfare poultry farms. Ten welfare (five layer and five broiler) and 15 conventional farms (five layer and ten broiler farms) were visited to collect environmental samples for identification and serotyping of Salmonella spp. The detection rate of Salmonella spp. was higher in the welfare farms than in conventional farms in both layer and broiler farms. In layer farms, Salmonella spp. was detected in 0.76% (1 out of 130) of samples from one of five welfare layer farms, but was not detected in the five in conventional layer farms. No significan ifference (P>0.05) was observed between the welfare and conventional layer farms. In broiler farms, Salmonella spp. was detected in 10.5% (21 out of 200) of samples from four of five welfare broiler farms and 3.5% (7 out of 200) of samples from five of ten conventional broiler farms, and a significant difference (p <0.05) was observed between the welfare and conventional broiler farms. Among 29 Salmonella spp. isolates, five isolates were serotyped to Salmonella enterica subsp. Enteritidis (n=2), Salmonella enterica subsp. Grampian (n=1), Salmonella enterica subsp. Virchow (n=1), and Salmonella enterica subsp. Senftenberg (n=1). These results suggest that microbial risks could be higher in welfare farms than in conventional farms due to easy access to open-air areas, environmental enrichment, and reduced use of antibiotics. Therefore, continuous monitoring and surveillance for Salmonella spp. is necessary to improve the microbiological safety of poultry meat.

1991년∼2000년의 우리 나라 원인 균별 식중독 발생 상황을 보면 살모넬라균, 황색포도상구균, 그리고 비브리오균에 의한 식중독이 우리 나라 식중독 사고발생의 85∼90%를 차지하는데, 특히 전체 식중독 발생건수에 대해 살모렐라균에 의한 식중독이 차지하는 비율이 1993년에서 97년도 사이에 46.5%, 1999년도와 2000년에는 36.3%로 보고되었다. 이처럼 살모렐라균은 대표적인 식중독균으로서 우리 나라 뿐만 아니라 전세계적으로 세균성 식중독의 주요 원인이 되고 있는데 식육, 달걀 둥 동물성 식품 및 가공품, 어패류 등이 주요 원인식품으로 알려져 있다.

여름철이 다가오면서 식품의 안전성이 더욱 요구되고 있다. 특히, 계란이나 메추리알에서의 살모넬라균의 오염은 매년 매스컴을 통해 소비자들에게 알려지면서 양계산물 소비에 큰 타격을 주기도 한다. 본고는 최근 국내에 새로운 항균, 세정제인 신 물질이 개발되어 식품업계에 돌풍적인 인기를 얻고 있는 제품이 있어 이를 소개하고 양계분야에 적용할수 있는 방안을 모색해 보았다. 본 제품은 현재 우리나라 식품의약품 안전청과 식품전문 분석센터, 일본의 각종 식품안전 분석센터로부터 그 효과 및 효능을 입증받은 제품으로 일본에서는 3년 전부터 업계에 상용화되고 있으며, 국내에서는 애그리코리아(주)(대표 서민교)에서 올 3월부터 시판에 들어갔다.

미국이 자국내 철강제 수입에 대한 관세부과 조치가 세계적인 문제가 되고 있는 시점에서, 러시아에 수출되고 있는 미국산 닭고기에서 살모넬라 등 위생에 문제가 될 수 있는 병원균이 검출되었다는 보도를 미국은 무역보복조치로 해석하고 있어 무역전쟁을 실감케 하고 있다. 축산물에 대한 안전이 식품의 안전성에 직결된다는 의식을 갖고 있는 우리나라의 배합사료제조회사들은, 자발적으로 가축에게 급여하는 사료에 대한 안전과 위생관리를 위하여 ISO는 물론 까다로운 것으로 알려진 HACCP 제도를 도입하고 있다. 이러한 노력이 종합적이고 기본적인 단계에 해당하는 양계농가에서도 함께 진행될 때 더욱 효과적인 결과를 얻을 수 있으리라 생각되어 살모넬라에 대한 일본의 농가단위 위생대책을 소개한다.
