Quantitative analysis of pesticides in chicken carcasses and environments of backyard raising system in rural area of Thailand

Abstract

A study of quantitative analysis of agricultural hazardous substances in chicken carcasses and the environment of backyard farming in rural Thailand determine the amount of the organophosphate and carbamate group pesticides in soil, water, chicken muscle and chicken liver in Mae Taeng District, Chiang Mai Province. A total of 44 samples, screening analysis by using the GT-Test kit found a positive result in the soil samples of Sop Peng Subdistrict. Advanced analysis by using the HPLC method was not found upon organophosphates and carbamates in the soil, water, and chicken muscle chicken liver. In addition, knowledge of using pesticides and behavior of using pesticides in conjunction with raising backyard chickens system was studied from 377 chicken raiser households in Mae Taeng District. The knowledge of using chemical pesticides was at a good level for 94.00 % of chicken raiser. In addition, the results found that, there was a significant relation between age and the level of knowledge of using pesticides (p<0.05). The older chicken raiser showed higher knowledge of using pesticides than due to life experiences and skills that develop by age. The highlight of impact on personal factors depend on age, income and knowledge about the use of pesticides. However, this valuable study of influence factor on knowledge and behavior in using pesticides emphasizes the importance for considering on age, income, and level of experience in promoting knowledge and safe practices in using pesticides among chicken farmers in backyard farming systems. The analysis of organophosphate and carbamate contamination in environmental samples and chicken carcasses is only a basic contamination assessment. The analysis should be combined of advanced analysis such as HPLC analysis, etc. In addition, behavior and knowledge in managing pesticide containers should be supported in creating knowledge, source eliminate to create additional knowledge and understanding for chicken raiser groups.
