Request for Information on Efficacy Testing of Ectoparasiticide Products

In a December 2021 Federal Register notice (86 FR 72251), NICEATM requested available data and information on approaches and/or technologies currently used for efficacy testing of ectoparasiticide products, such as products to prevent flea and tick infestations on dogs and cats. Submitted information will be used to assess the state of the science and determine technical needs for non-animal test methods used to evaluate the efficacy of ectoparasiticides on dogs and cats and to facilitate their incorporation into a testing strategy for regulatory purposes.
