Cypermethrin, deltamethrin, and hexachlorobenzene contents in milk and dairy products in Tehran, Iran

ABSTRACT

The aim of this study was to determine pesticide residues in milk and dairy product samples from Tehran, Iran. A total of 50 samples (raw milk, ultra-high temperature milk, pasteurised milk, pasteurised and traditional butter, and pasteurised and traditional cheese) were randomly collected from June to August 2022, and their pesticide contents were examined through high-performance liquid chromatography. Out of the 50 samples, 38, 42, and 100% contained cypermethrin, deltamethrin, and hexachlorobenzene over the maximum residue limit set by the EU, respectively. Traditional butter had Cypermethrin and hexachlorobenzene means concentration of 75.64 ± 22.40 and 61.69 ± 17.78 µg/kg, respectively.
