Subform VII: Scientific Study
1. Study Reference
Title Carcinogenicity study with ethofumesate technical in Swiss albino mice
Date 01-FEB-02
2. a) Is an extension needed to translate the document?
No
3. Type of incident identified in the study
New health or environmental hazard
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)
In an 18-month mouse carcinogenicity study with ethofumesate technical, no carcinogencity was observed. However, at 10,000 ppm, uterine epithelial thickening and squamous metaplasia was observed in terminally sacrificed high dose females which was considered treatment-related. However, there were no associated histopathological or other changes in endocrine organs (ovaries, adrenals and pituitary) or in mammary glands.
5. a) Was the study discontinued before completion?
No
5. b) Provide the reason for discontinuation
6. If the study is ongoing, what is the expected completion date?
For Registrant use only
7. Provide supplemental information here
This study does not report any carcinogenicity and the existing chronic POD is lower than the NOAEL for this study, so these results would not affect the current risk assessment.
