BACKGROUND: Agricultural use and pest control purposes of pesticides may lead to livestock products contamination. Thiodicarb and its degraded product, methomyl, are carbamate insecticides that protect soya bean, maize, fruit, and vegetables and control flies in animal and poultry farms. For maximum residue limit enforcement and monitoring, the JMPR residue definition of thiodicarb in animal products is the sum of thiodicarb and methomyl, expressed as methomyl. This residue definition was set to consider the fact that thiodicarb was readily degraded to methomyl in animal commodities. And therefore the simultaneous analytical method of thiodicarb and methomyl is required for monitoring in livestock products. METHODS AND RESULTS: The study was conducted using a quick, easy, cheap, effective, rugged, and safe (QuEChERS) method and HPLC-MS/MS to determine the thiodicarb and methomyl in livestock products. The limit of quantitation (LOQ) was 0.01 mg/kg for livestock products, including beef, pork, chicken, milk, and egg. The coefficient of determinations (r²) for the calibration curve were > 0.99, which was acceptable values for linearity. Average recoveries at spiked levels (LOQ, 10LOQ, and 50LOQ, n=5) in triplicate ranged from 73.2% to 102.1% and relative standard deviations (RSDs) were less than 10% in all matrices. CONCLUSION: The analytical method was validated for the performance parameters (specificity, linearity, accuracy, and precision) in livestock products to be acceptable by the CODEX guidelines.

This study aimed to evaluate the effectiveness of propolis extract as a natural preservative for livestock products in term of chemical and microbiological characteristics by meta-analysis. The stages carried out in this study were identification, selection, checking suitability, and the resulting selected articles were used in the meta-analysis. The selection results obtained a total of 22 selected journal articles consisting of 9 articles for analysis of the antimicrobial activity of propolis extract and 13 articles for analysis of the chemical and mirobiological characteristics of livestock products. The articles were obtained from electronic databases, namely Science Direct and Google Scholar. The model used in this study is the random-effect model involving two groups, control and experimental. Heterogeneity and effect size values were carried out in this study using Hedge's obtained through openMEE software. Forest plot tests and data validation on publication bias was obtained using Kendall's test throught JASP 0.14.1 software. The results showed that there is a significant relationship between propolis extract with the results of the antimicrobial activity (p<0.05). In addition, the results of the application of propolis extract on the livestock products for the test microbes and the value of thiobarbituric acid reactive substances (TBARs) showed significant results (p<0.05). Conclusion based on the random-effect model on the effectiveness of antimicrobial activity of propolis extract and their apllication as a natural preservative of the chemical and microbiological characteristics of livestock products is valid by Kendall's test (p>0.05). Propolis in this case effectively used as natural preservatives in livestock products.

세계 유기농가 수는 약 25만호에 달하며 세계시장의 유기제품판매액은 27,800백만불(2006)에 이른다. 유기축산물 주요소비국은 EU 및 미국이며 주요품목은 우유, 양고기, 쇠고기이다. EU와 미국의 유기식품 시장점유율은 2% 미만이며 이중 유기축산물의 비중은 17%(미국)이다. 유기축산물의 주된 유통통로는 수퍼마?R(유럽), 건강식품전문매장(미국)이며 Tesco, Walmart 등과 같은 대형체인점의 판매비중도 증가하는 추세이다. 국가간 유기축산물교역량은 극히 적으며 주로 개발국 특히 유럽국가 간에 활성화하고 있다. 앞으로의 유기식품시장은 남미, 중동, 오세아니아를 중심으로 급성장할 것이다. 그러나 성장속도는 높은 가격, 유통인프라 미비, 유사유기축산물의 시장진입, 국가간의 인증 기준차이 등에 의해 제한될 것이다. 유기축산 선발국들은 유기농업을 농촌사회의 발전, 농업 생산방식의 다양화, 환경개선 등을 위한 정책적 수단으로 활용하고 있다.

축산식품과 그 가공품의 소비량이 증가함에 따라 이로 인한 식중독 또한 꾸준히 발생하고 있어 다양한 축산식품과 그 가공품에 대한 안전관리가 필요하다. 본 연구는 50가지 축산식품과 그 가공품에 대해 대한민국의 성인을 대상으로 축산식품의 섭취실태를 조사하기 위해 전국의 성인 남녀 1,500명을 대상으로 설문조사를 진행하였다. 성별, 나이별, 지역 크기별, 직업별, 지역별로 섭취량 및 섭취빈도를 조사한 결과, 축산식품의 섭취량과 섭취빈도에 가장 영향을 미치는 것은 지역의 차이였다. 성별로는 남성이 여성보다 섭취량 및 섭취빈도가 높았으며, 나이별로는 20대에서 가장 높고 나이가 증가함에 따라 섭취량 및 섭취빈도가 감소하는 경향을 보였다. 지역크기별로는 식육 및 그 가공품의 경우 대도시, 우유 및 유가공품과 알류 및 알 가공품은 중소도시에서 섭취량 및 섭취빈도가 높았으며, 직업별로는 학생이 축산식품과 그 가공품에 대한 섭취량과 섭취빈도가 높았다. 지역별로는 서울과 인천/경기, 부산/울산/경북에서 섭취량과 섭취빈도가 높았다. 조사대상자 전체(1,500명)의 섭취빈도를 조사한 결과, 한 달에 가장 자주 섭취하는 식육과 그 부산물류에서는 돼지고기, 닭고기, 소고기 순이었고, 축산가공품에서는 햄, 양념된 돼지불고기, 소시지 순이었으며, 우유 및 유가공품에서는 우유, 액상 요구르트, 호상 요구르트 순이었고 알류 및 알 가공품에서는 계란말이, 계란찜, 삶은 계란 순으로 조사되었다. 결론적으로 인구집단에 따른 50가지 축산식품과 그 가공품의 섭취량과 섭취빈도를 조사한 결과, 인구집단에 따라 선호하는 축산식품의 종류가 다르며 섭취하는 양에도 차이를 보였다. 따라서 본 연구 결과는 안전한 축산식품 섭취 관련 식중독 교육에 활용할 수 있으며, 축산식품과 그 가공품의 병원성 식중독균에 대한 위해평가 과정에서 노출평가에 필요한 섭취량 데이터베이스 구축에 활용 가능할 것으로 사료된다.

전국의 학교 급식 및 군 급식 등 대규모 농축수산물의 물류가 이루어지고 있으나, 안심 농축수산물에 대한 물류정보가 거짓표시 되어 안전한 식품공급에 사회적인 이슈가 되고 있다. 외국산 저 품질 축산물을 국내산 고품질 축산물로 둔갑시키고, 일반 농산물을 친환경 농산물로 속이고, 오염된 채소류를 신선한 채소류로 속여서 학교 및 집단급식소에 식자재로 납품하고 있다. 본 논문에서는 부정 농축수산물의 물류정보에 대한 보안 방법과 부정 농축수산물 피해로 인한 법적인 책임소재 증거자료로 e-Discovery시스템을 적용하여, 책임 소재와 피해 보상에 대한 연구가 필요하다.

Imidacloprid is a neonicotinoid insecticide widely used for insect control in a variety of crops. The evaluation of imidacloprid total residues in animal feeds derived from crop by-products is required to ensure the safety of livestock products. We performed simultaneous LC/MS/MS analyses of imidacloprid and its metabolites in five different livestock products including beef, pork, chicken, milk and egg from domestic markets. The methods for sample preparation and instrumental analysis were established by modifying QuEChERS method to meet the Codex guidelines. The methods generated 0.0035 mg/kg of the limit of determination (LOD), 0.01 mg/kg of the limit of quantitation (LOQ) and standard calibration linearity with >0.983 of the coefficients of determination (R²). The methods exhibited the recovery values of imidacloprid and its metabolites ranging from 65.66 to 119.27% without any interference between matrices. Imidacloprid total residues in the livestock products were found as values lower than the LOQ and maximum residue limits (MRLs). This study suggests that the methods are successfully applicable for the safety evaluation of imidacloprid total residues in livestock products from domestic markets.

Salmonella Enteritidis is responsible for causing foodborne diseases upon consumption of egg products. While cases of S. Enteritidis isolation from eggs have been reported in other countries, no such cases have previously been reported in Korea. In this study, we report the first isolation and identification of S. Enteritidis from domestically distributed eggs in Korea. Eggs were collected from eight countrywide grocery stores during different seasons between 2011 and 2012. Egg contents and washing solution of egg shells were incubated in buffered peptone water, and the enriched broth was further enriched in tetrathionate broth and Rappaport-Vassiliadis. The secondary enriched broth was streaked on xylose lysine desoxycholate agar. The suspected colonies were confirmed to S. Enteritidis by a biochemical test, serotyping, and PCR test. Genetic relatedness among the isolates was analyzed using Diversilab Salmonella kit. Three strains of S. Enteritidis were isolated from egg contents and egg shells collected from grocery stores of the Eumseong-city in the fall of 2011. All three stains showed resistance to chloramphenicol, streptomycin, nalidixic acid, and ampicillin by the disk diffusion method. In addition, the isolates showed more than 99% DNA homology, indicating that they were presumably identical strains. Therefore, there is a requirement to monitor and control against S. Enteritidis from eggs in Korea.
