Now that Halloween candy has been collected through Trick or Treating and Trunk or Treat events, the Danbury Health Department is offering some reminders for parents.  They are asked to be on the look out for so-called Rainbow Fenanyl.  The brightly colored pills have been spotted in two dozen states, but no reports in Connecticut.  The DEA has seized fentanyl pills in candy packages elsewhere and say traffickers use bright colors for many reasons, targeting children is not one of them.  General Halloween candy safety tips from the City Health Department include not eating candy not commercially wrapped or if the wrapping has been tampered with.  For any child with food allergies, parents should check all labels before consuming.
