3. Type of incident identified in the study
Increased health or environmental risk
4. Describe the incident identified in the study (e.g. study demonstrates an increased risk to non-Hodgkin's Lymphoma after exposure to pesticide X)
BCS is submitting new information to PMRA related to cyfluthrin technical as BCS has become aware of a study that has not previously been reported. This information is not necessarily a new adverse effect of the subject chemical, but is rather new information submitted for the agencys own review and evaluation. The non-GLP honey bee acute toxicity study being submitted pre-dates current guidelines for honey bee acute contact (OECD 214) and acute oral (OECD 213) toxicity testing and deviates from the current guidelines by testing only 20 bees per treatment level for 24 hours. At test termination, 24 hour acute contact and acute oral LD50 values were generated. The contact LD50 reported in the study is lower than the current contact LD50 value for honey bees (96 hour LD50). However the study from which the 96 hour was generated is considered more robust and reliable as the study was performed for 96 hours with a total of 225 bees per treatment level.
5. a) Was the study discontinued before completion?
No
