It has also tendered apology "unreservedly" to the
baby's parents and the donor mother.
Authorities reassured that the risk of the baby contracting the disease is
negligible because of "good health of all those involved."
As a precautionary measure, blood and milk samples have been taken from the
baby for testing, and results are expected in a week, with a routine
confirmation test to be conducted in 12 weeks.
The baby's grandmother, Peggy, said a nurse had given a bottle of milk to her
daughter-in-law to feed her baby but returned in about five minutes later
saying that it was the wrong bottle.
The health service spokesman assured that any issues unaddressed by the investigation
would be looked into to ensure that a similar incident would not happen.
The staff who were involved in the incident were given counseling about the
importance of abiding by the protocols related to expressed breast milk.
