Using gloves while feeeding infants

I'm looking for clarification regarding the use of gloves and bottle feeding an infant. The school is currently required to wear gloves only when the bottle contains breast milk. Upon a quick review of the "All About the ITERS-R" with the director, we were unable to find out if gloves must be worn at all times for bottle feeding, only with breast milk, or not required if hands are washed prior to feeding. Please inidcate where this is speciffically addressed so it can be shared with the school's corporate office. Thanks.
