“…For milk samples also the same OCP compounds, cyclodiene compounds and organophosphorus compounds conducted for fodder samples were analyzed. Milk samples from zone V contain the residual concentration of dimithioate of 0.13 ppm (Figure-5), which is higher than concentrations of 0.01 μgl −1 for dimithioate reported by Fagnani et al [15]. In the Table- present study except dimithioate all other OCPs compounds, cyclodiene compounds and organophosphorus compounds were below the detection limit in milk samples.…”

“…Residual concentration of 0.001 ppm and 0.02 ppm were reported by Panseri [12] and Aulakh [14] respectively in the fodder samples, which are far below the MRL value (0.01 ppm) specified by EU (CE:398: 2005) in fodder for heptachlor. Fagnani et al [15] reported the residual concentration of dimethoate in fodder sample as 0.01 μgl −1 . For milk samples also the same OCP compounds, cyclodiene compounds and organophosphorus compounds conducted for fodder samples were analyzed.…”

AbstractAim: The present study was conducted to find the organochlorine pesticide (OCP) and organophosphorus pesticide (OPP) residues in fodder and milk samples along Musi river belt, India. Materials and Methods: Fodder and milk samples collected from the six zones of Musi river belt, Hyderabad India were analyzed by gas chromatography with electron capture detector for OCP residues and pulsated flame photometric detector for the presence of OPP residues. Results: The gas chromatographic analysis of fodder samples of Zone 5 of Musi river showed the residues of dicofol at concentration of 0.07±0.0007 (0.071-0.077). Among organophosphorus compounds, dimetheoate was present in milk samples collected from Zone 6 at a level of 0.13±0.006 (0.111-0.167). The residues of OCPs, OPPs and cyclodies were below the detection limit in the remaining fodder and milk samples collected from Musi river belt in the present study. Conclusion:The results indicate that the pesticide residues in fodder and milk samples were well below the maximum residue level (MRL) values, whereas dicofol in fodder and dimethoate in milk were slightly above the MRL values specified by EU and CODEX.

“…Fagnani et al (2011) performed a similar study in Pernambuco, Brazil, and found 6 (20%) out of 30 samples of raw milk contaminated with OPP, 5 (16.7%) were contaminated with CB, and one sample with both pesticides. Nero et al (2007) Melgar, Santaeufemia and Garcia (2010) detected OPP residues of dichlorvos (5.78 %), coumaphos (2.06 %) and methyl-parathion (0.83 %) in 242 raw milk samples.…”

ResumoNo Brasil, as exigências legais quanto ao controle de qualidade do leite cru se restringem à análise microbiológica, físico-química e à pesquisa de antimicrobianos. Contudo, os agrotóxicos podem ser detectados no leite após a exposição dos animais em lactação a esses agentes. O objetivo deste trabalho foi pesquisar a presença de organofosforados (OF) e carbamatos (CB) em amostras de água e de alimentos fornecidos às vacas leiteiras e também no leite produzido por esses animais. Todas as amostras foram analisadas por cromatografia gasosa com um detector de nitrogênio e fósforo (CG-NPD). Das 30 amostras de leite cru analisadas, os resíduos de OF foram detectados em 5 (16,67%), todos abaixo dos limites máximos de resíduos (LMR) determinados pela legislação e não foram detectados resíduos de CB no leite. Os agrotóxicos pesquisados não foram detectados nas amostras de água. Do total de 98 amostras de alimentação animal, foi detectado OF em 28 amostras (28,57%), CB em 18 (18,37%) e ambos em 1 amostra (1,02%). Em 3 propriedades se constatou a contaminação do leite pelos mesmos princípios ativos de OF detectados na alimentação animal. A grande ocorrência de resíduos de agrotóxicos na alimentação animal alerta para ausência de controle na sua produção, podendo essa ser uma importante fonte de contaminação do leite por esses compostos. Palavras-chave: Leite cru, resíduos de agrotóxicos, rebanho leiteiro, contaminação AbstractIn Brazil, the legal requirements regarding the quality control of raw milk are restricted to microbiological, physico-chemical and antimicrobial research. However, pesticides can be detected in milk after exposure of dairy cows to these agents. The present study aimed to search for the presence of organophosphorus (OPP) and carbamate (CB) pesticides in samples of water and feedstuff supplied to dairy cattle and also in the milk produced by these animals. All samples were analyzed by gas chromatography with nitrogen phosphorus detector (GC-NPD). Residues of OPP were detected in 5 (16.67%) out of 30 raw milk samples, all bellow maximum residues limits (MRL). CB residues were not detected in milk. Pesticide residues included in the research were not detected in water samples. Within the 98 samples of the diet's components of the animals analyzed, OPP were detected in 28 (28.57%) samples, CB in 18 (18.37%), while both pesticides were detected in 1 sample (1.02%). In 3 dairy farms it could be noted milk contamination by the same active ingredient of OPP that were detected in animal feed. High levels of animal feed contamination detected in this study raise concerns to the absent control in animal feed production and may represent an important source of milk contamination by these compounds.

“…Pesticides containing organochlorine (OC) compounds undergo bioamplification through the food chain (Angulo et al, 1999;Borgå et al, 2001). Fagnani et al (2011) defined organophosphorus (OP) pesticides as esters, amides or thiol derivatives of phosphoric acid. OP pesticides are easily hydrolyzed and therefore do not persist in the environment.…”

Blood samples of sheep and rabbits from five different villages of Jimeta-Yola, Adamawa State, Nigeria were collected for determination of organochlorine and organophosphorus pesticide residues. Preparation of blood samples was carried out using standard procedure of QuEChERS method of extraction. The concentrations of all the pesticides in blood samples of sheep and rabbits were determined using Gas Chromatography-Mass Spectrometry (GC-MS) Shimadzu (GCMS-QP2010), equipped with electron capture detector. Organochlorine and organophosphorus pesticide residues were significantly higher in the blood samples of sheep than in the blood samples of rabbits. According to the concentration and detection frequency, o,p'DDE, p,p'DDD, aldrin and dieldrin were the most dominant compounds among the organochlorine pesticide residues. The results of this study showed that highest concentration of o,p-DDE in blood samples of sheep was detected at Namtari village with a mean value of 0.034±0.001 mg/l. For o,p'-DDT, the highest concentration (0.014±0.001 mg/l) was observed at Wurojabbe , p,p'-DDD had the highest concentration at Doubeli with a value of 0.028±0.001 mg/l. Also, the highest concentration of aldrin in the blood samples of sheep was detected at Namtari with a value of 0.028±0.001 mg/l. For dieldrin, the highest concentration was recorded also at Namtari with a mean value of 0.036±0.001 mg/l. Despite the bans and restrictions on the use of some of these pesticides in Nigeria, the observed concentrations of the studied pesticides from these villages could explain either their persistence in the environment or continued use in the study area. Hence, routine monitoring of pesticide residues in these villages is necessary for prevention, control and reduction of environmental pollutions, so as to minimize health risks.
