據加拿大衛生部消息，6月19日加拿大衛生部發布PRVD2015-05號文件，有害生物管理局（PMRA）發布右旋苯醚菊酯（D-phenothrin）的再次評估提案，擬批準該物質繼續登記。

加拿大有害生物管理局認為，經過評估發現，按照標簽說明來使用，右旋苯醚菊酯不會對人體健康以及環境構成威脅。右旋苯醚菊酯是一種內吸性擬除蟲菊酯類殺蟲劑，通過觸殺和胃毒快速起效，可以防治多個位點上的大量害蟲。

部分原文報道如下：

After a re-evaluation of the insecticide d-phenothrin, Health Canada's Pest Management Regulatory Agency （PMRA）， under the authority of the  Pest Control Products Act and  Regulations, is proposing continued registration for the use and sale of d-phenothrin products in Canada.

An evaluation of available scientific information found that products containing d-phenothrin do not present unacceptable risks to human health or the environment when used according to the proposed label directions. As a condition of the continued registration of d-phenothrin, new risk-reduction measures are proposed for the end-use products registered in Canada. No additional data are being requested at this time.
