    • Biomonitoring of the hematological, biochemical and genotoxic effects of the mixture cypermethrin plus chlorpyrifos applications in bovines

      External antiparasitic agents applied in bovine production represent a risk to consumers of meat products, espe- cially if the conditions of their use are not strictly respected. The post-mortem control of residues in meat is an activity that must be updated and reinforced by the biomonitoring of live animals and the use of analytical tools to help identifying signs of early warning risks. The objective of the present study was to carry out a pre- slaughter biomonitoring approach in Aberdeen Angus cattle and crosses (n = 12) with the application of a com- mercial formulation of cypermethrin ...
    • Evaluation of the genotoxic potential of cypermethrin, chlorpyrifos and their subsequent mixture, on cultured bovine lymphocytes 

      Ferré, Daniela Marisol; Ludueña, Héctor Ricardo; Romano, Raquel; Gorla, Nora Bibiana María (Comité editorial Chemosphere Journal, 2019-11-09)
      Cypermethrin (CYP) and chlorpyrifos (CPF) are insecticides/parasiticides used in the production of fruits, vegetables and beef cattle. These substances or their metabolites are frequently reported as residues in food, whose consumption in a diet implies a genotoxic risk. The potential for chronic toxicity of CYP and CPF is unclear, and only a few genotoxicological evaluations based on their mixture have been performed. The aim of this study was to evaluate the genotoxic potential of CYP, CPF and CYP þ CPF in five concentrations, from 5.9 to 175 mg/mL, on bovine lymphocytes. By means of the ...
    • Reference values for acetyl and butyrylcholinesterases in cattle under actual management conditions, hepatic and renal function by application of chlorpyrifos

      Chlorpyrifos is an anticholinesterase organophosphate insecticide widely used in Argentina in the production of food derived from animal, fruit and horticultural origin and is reported as a residue within these products. Local reference values for acetyl and butyrylcholinesterase were determined in Aberdeen Angus bovine and cross bred cattle (n D 25), a requirement to be able to evaluate toxicity of commercial organophosphate and carbamate formulations. The activity of cholinesterase enzymes presented an overall mean of 2,183.00 § 485.6 IU L¡1 for erythrocyte acetylcholinesterase and 203.1 § ...
