“…Pesticide residues have been detected in milk frequently in various researches. A study conducted by the USDA Pesticide data programme showed that 96% of the samples contained dicchloro-diflouro ethane (DDE), 99% DPA, 41% dieldrin, 25% synthetic pyrethroids and 9% had 3 hydroxyfurans which is a breakdown product of carbamate insecticides (Thompson and Fishwick, 1970). Sassine et al (2004) studied cypermethrin contamination Iftikhar et al 483 in dairy milk samples of Brazil.…”

The transfer of organophosphate and pyrethroid pesticides in dairy cattle's milk when fed on agroindustrial by-product diet was assessed in this study. The transfer and accumulation of such pesticide in cattle fat tissue and milk was also assessed and the adverse effect on cattle's and human health was also studied. For that purpose, about 80 milk and 30 diet samples were collected from various dairy farms. All samples were extracted with acids using "quick, easy, cheap, effective, rugged, and safe" (QuEChERS) method and analyzed through gas chromatography-mass spectrometry (GC-MS). The results show that about 40 and 20% of milk samples had greater content of cypermethrin+chloropyrifos and porfenofos than their maximum residue limits as suggested by World Health Organisation (WHO). Cypermethrin, chloropyrifos and profenofos were present at concentration greater than their maximum residue limits in mixed diet whereas profenofos was completely absent in sugarcane khal and was present in traces in cotton khal but remained within the maximum residue limit. Nonetheless, transfer of residue of parent cypermethrin, chloropyrifos and profenofos to milk was not consistent with diet in all dairy milk samples. This revealed the contention that some other sources such as drinking or inhaling contaminated water or dust are also contributing to pesticide contamination in milk. Cancer potency factor for cypermethrine in children and adults remained within the recommended value. Generally, although pesticides residue in milk was not high enough to cause cancer risk in human, they might cause adverse health effect and delayed toxicity due to their long term accumulation and persistence within cattle's body. Therefore, there was an urgent need to estimate their contents in dairy cattle milk in order to provide a baseline for the health ministry to make safety regulations.

Pesticide residues in foodstuffs in Great Britain: Organochlorine residues in imported cereals, nuts, pulses and animal foodstuffs

1973

View full text Add to dashboard Cite

Results are presented for the determination of organochlorine insecticide residues in imported cereals, nuts, pulses and animal foodstuffs for the 2 year period July 1969 to June 1971. BHC was found in all but four of the 248 samples examined but only in 25 (10%) did the level exceed 0.5 mg/kg. DDT was found in 39% of the samples of which three samples of wheat contained more than 1 mg/kg and two samples of cottonseed cake more than 0.5 mg/kg. The other commodities sampled had less than 0.2 mg/kg. DDE was detected in trace amounts in 26 % of the samples examined.

Gamma‐HCH in eggs and poultry arising from exposure to thermal vaporisers

et al. 1980

Levels of gamma‐HCH have been determined in poultry tissue and eggs taken from poultry houses in which thermal vaporisers were operated. During continuous operation for 14 months, residue levels of gamma‐HCH in both substrates were related closely to changing levels of insecticide in the vaporiser; up to 46 mg kg−1 (on a fat basis) was found in tissue and up to 4.0 mg kg−1 (on a whole liquid basis) in eggs. Where the vaporisers were operated discontinuously, maximum levels were 6.7 mg kg−1 in tissue and 0.53 mg kg−1 in eggs.
