Out of an abundance of caution" officials with the church have requested that parents of children who attended "immediately retrieve" the eggs and keep them in a safe place until they can be returned to the parish office and exchanged for new candy.

"We ask that parents not throw the eggs and their contents away, but return Sunday's eggs to Christ the King Parish Office as immediately as possible," church spokeswoman Mary Mullins said in an email. Volunteers are on site to exchange new candy for the children.

"It is possible, but unlikely, that another separate egg belonging to a volunteer was inadvertently and accidentally mixed in with the volume of 1,500 eggs that were prepared by the Youth Ministry for the hunt. The egg may contain a volunteer's medicine that is unlikely to, but could potentially, be harmful if ingested," Mullins wrote.

Officials believe the egg in question has been recovered but are conducting a candy exchange to ensure safety.
