Applicant's summary and conclusion

Conclusions:
The developmental toxicity TDLo ( Lowest published toxic dose ) of clioquinol in rat by the oral exposure was observed at a dose concentration of 1528 mg/kg .
Executive summary:

The developmental toxicity TDLo ( Lowest published toxic dose ) of clioquinol in rat by the oral exposure was observed at a dose concentration of 1528 mg/kg . This indicates that clioquinol does not exhibit toxic effects to rat by the oral route below the above mentioned dose.
