Summary of the final regulatory action:

Resolution No. 024 of June 10, 2011, states that the Ministry of Agricultural Development of Panama (MIDA), adopts the decision to ban 11 different active ingredients for all agricultural uses, including Methyl-parathion. This measure is adopted for the following reasons:
1) Pesticide molecules listed cause a relevant risk to public health and other living organisms due to their extreme and high toxicity; proven persistence, bioaccumulative properties, high carcinogenic, mutagenic, teratogenic and infertility risks.
2) Current measures to regulate exposure to these substances will not reduce risks to acceptable levels. In addition, there are alternative, effective, economically competitive and viable products available for agricultural production. Another reason for the prohibition of agricultural formulations based on the active ingredient Methyl-parathion is their highly harmful effects on public health and environmental pollution, as indicated in numerous international studies. Under this decision, all sales licenses for these products were canceled in Panama.

The reasons for the final regulatory action were relevant to: Human health and environment

Date of entry into force of the final regulatory action: 17/06/2011
