Nouveau danger pour la santé ou pour l'environnement
Oral (gavage) administration of Amitraz to F1-Generation rats for at least 83 days at a concentration of 7.5 mg/kg, preceded by exposure in utero and via lactation route, resulted in significant increases in the number of primordial follicles for left, right, and both ovaries compared to those animals administered the Control article (Group 1). Pairwise comparisons were not significant for the mid- or low dose levels. The mean total primordial follicles were reported to be 100, 109, 119 and 156 for the 0, 0.5, 1.5 and 7.5 mg/kg/day treatment groups. Although corpora lutea were present for all animals on study, seven of the 23 Group 4 animals had noted regression of this structure throughout, compared to one Group 1 animal.The incidences of this observation were 5 and 6 in the low and mid-dose level animals.

The Consortium believes that these observations will not prove to be toxicologically relevant following planned additional observations as outlined below. However, the Consortium is reporting these preliminary observations in an abundance of caution.
