The level of organochlorine pesticides in 229 samples of Spanish meat and meat products of different species (lamb, pork, beef and poultry) was investigated. Chlorinated residues were quantitated by gas-liquid chromatography with electron capture detector using packed and capillary columns. Hexachlorobenzene (HCB) and hexachlorocyclohexane (HCH) were detected in all samples. In general, lamb appeared to be more heavily contaminated by HCB and HCH, which reached maximums of 178 ppb (μg/kg on a fat basis) and 505 ppb, respectively. The level of HCB averaged 49 ppb in lamb; varied between 8–18 ppb in pork and beef products; and amounted to 26 ppb in fresh poultry sausages. Of the three isomers of HCH determined, the γ-HCH (lindane) was most frequently detected; 100% in lamb and pork (both meat, cured sausage and pork bologna), and 64 to 94% in fresh sausages of poultry and beef. The level of the HCH group averaged 112 ppb in lamb, 85 ppb in poultry, nearly half that much in pork and pork products, and around 20–40 ppb in beef products. Dieldrin was the only chlorocyclodiene detected: 8 to 15% in pork products, and 28% in fresh poultry sausage. The DDTs in lamb showed 83% of detection, especially in the pp' form of DDE and DDT. The overall contamination with DDT and its metabolites was found to be very moderate averaging 25 ppb, with a maximum of 91 ppb. No residues of aldrin, endrin, heptachlor, heptachlor epoxide, chlordane, methoxychlor, endosulfan or trans-nonachlor were detected.

Organochlorine Pesticide Residues

Determination of organochlorine pesticide residues in shrimp is very important to ensure the consumer’s safety and to fulfill the importer’s demand. Therefore, a simple and efficient multiple organochlorine pesticide residues analytical method using quick, easy, cheap, effective, rugged and safe (QuEChERS) extraction technique and Gas Chromatography coupled with Electron Capture Detector (ECD) has been developed and validated for the determination of 19 organochlorine pesticides (α- BHC, δ- BHC, β- BHC, γ- BHC, Heptachlor, Aldrin, Heptachlor Epoxide, γ- Chlordane, α- Chlordane, α- Endosulfan, 4,4 DDE, Dieldrin, Endrin, 4,4 DDD, β- Endosulfan, 4,4 DDT, Endosulfan sulphate, Methoxychlor, and Endrin Ketone) in shrimp. The method was validated by evaluating the accuracy, precision, linearity, limit of detection (LOD) and limit of quantification (LOQ). The average recoveries of the selected pesticides ranged from 84% to 106% with RSDr ≤ 14% in four fortification levels of 0.05, 0.1, 0.2 and 0.3 mg kg-1. The linearity was ≥ 0.996 for all of the selected pesticides with matrix matched calibration standards. The LOD ranged from 0.003 to 0.009 mg kg-1 and the LOQ was 0.05 mg kg-1. This method was applied successfully for the residue analysis of 40 shrimp samples collected from different regions in Bangladesh.SAARC J. Agri., 16(1): 81-93 (2018)
