Climate conditions associated with the occurrence of pyrethroid residues in bulk milk tank

Abstract

The present study attempted to identify climate conditions that are associated with the occurrence of pyrethroid residues using a multivariate principal component analysis (PCA). A total of 132 raw milk samples were collected from dairy farms in Minas Gerais State -Brazil and analyzed for seven analytes using gas chromatography with electron capture detection. Of the 132 milk samples, pyrethroid residues were identified in 14 (10.6%) milk samples, of which 12 (9.1%) and two (1.5%) milk samples had the identification of cypermethrin and deltamethrin, respectively. From those samples, nine (6.8%) milk samples were regarded as non-compliant for cypermethrin with this analyte concentration above the maximum residue limits set by Brazilian legislation. A PCA assessing pyrethroid residues in bulk tank milk demonstrated that the average temperature and the Temperature-Humidity Index were associated with pyrethroids residues in bulk milk tank, although the relative humidity was inversely correlated. Thus, the data analysis indicated that the pyrethrid residues associated with some climate conditions can predict the moments with higher risk of occurrence of pyrethroid residues in bulk tank milk.Keywords: veterinary drug, pesticide, raw milk, seasonality, dairy cow Palavras-chaves: medicamento veterinário, pesticida, leite cru, sazonalidade, bovino leiteiro RESUMO O presente trabalho objetivou identificar fatores climáticos associados à ocorrência de resíduos de piretroides em amostras de leite de tanque por análise multivariada de componentes principais (ACP).
