METABOLITES & DEGRADATES:
2,6,-difluorobenzoic acid
2,6,-difluorobenzamide
4-(2-chloro,á, á, á trifluoro-p-tolyoxy)-2-fluorophenyl urea (WL129183)
4-(2-chloro,á, á, á rifluoro-p-tolyoxy)-2-fluoroaniline (WL15096)

• The database is adequate for establishment of tolerances on the requested commodities, except for a developmental toxicity study in rat which was classified as unacceptable/guideline. However, this study provides adequate information to conclude that flufenoxuron was not fetotoxic at doses up to the limit dose. Only an acute oral toxicity study in rat was submitted, which was placed in Toxicity Category IV. Acute toxicity studies are not required for import tolerance.

European Union: Rapid Alert System for Food and Feed

Alert Notifications are sent when the food or feed presenting the risk is on the market and when immediate action is required. Alerts are triggered by the Member State that detects the problem and has initiated the relevant easures, such as withdrawal/recall. The notification aims at giving all the members of the network the information to verify whether the concerned product is on their market, so that they also can take the necessary measures.
