Breastfeeding advocates are calling for the government to introduce legislation to stop hospitals accepting free supplies of baby formula from manufacturers after parents were given potentially harmful samples.
The Baby Friendly Hospital Initiative Hong Kong Association says the practice, which is common in Hong Kong, violates a World Health Organisation code aimed at promoting breastfeeding.
It claims hospitals that give samples to mothers undermine the promotion of breastfeeding and help foster an atmosphere in which formulas are seen as acceptable or even better than breast milk for babies' health and development.
Seventeen parents of newborns were each mistakenly given a 400 gram can of Progress Gold by the Tsuen Wan Adventist Hospital between October 19 and 24.
Progress Gold, made by US pharmaceutical company Wyeth, is intended for children aged one to three, and could potentially cause kidney problems in younger children because of its higher protein content.
The hospital has said it will stop handing out samples and accepting free supplies from manufacturers.
