Climate conditions associated with the occurrence of antimicrobial and macrocyclic lactone residues in bulk tank milk Arq. Bras. Med. Vet. Zootec.
Picinin,L.C.A.; Toaldo,I.M.; Hoff,R.B.; Souza,F.N.; Leite,M.O.; Fonseca,L.M.; Diniz,S.A.; Silva,M.X.; Haddad,J.P.A.; Cerqueira,M.M.O.P.; Bordignon-Luiz,M.T..
ABSTRACT The present study aimed to identify the climate condition parameters that are associated with the occurrence of antimicrobial and macrocyclic lactone residues in bulk tank milk using a multivariate principal components analysis (PCA). A total of 132 raw milk samples were collected at dairy farms in Minas Gerais State in Brazil and analyzed for 35 analytes, comprising macrocyclic lactones and antibacterials, using liquid chromatography coupled with mass spectrometry in tandem mode spectrometry. Of the 132 samples, 34 (25.76%) bulk tank milk samples were positive for at least one analyte. PCA showed that antimicrobial residues in bulk tank milk occurred less frequently on days with a higher average temperature, maximum temperature and...

Climate conditions associated with the occurrence of pyrethroid residues in bulk milk tank Arq. Bras. Med. Vet. Zootec.
Picinin,L.C.A.; Toaldo,I.M.; Hoff,R.B.; Souza,F.N.; Leite,M.O.; Fonseca,L.M.; Diniz,S.A.; Silva,M.X.; Haddad,J.P.A.; Cerqueira,M.M.O.P.; Luiz,M.T.B..
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...
