Establishes public awareness campaign advising pregnant women, new parents, and women who are breast feeding about dangers of casual milk sharing.

New Jersey's A1644 requires the Commissioner of Health to create a public awareness campaign targeting pregnant women, new parents, and breastfeeding mothers. The campaign must inform these groups about the risks of "casual milk sharing" (informal, unsanctioned milk donations outside milk banks), including disease transmission, contamination, and the FDA's warning against using milk from unknown sources. It also provides details on regulated human milk banks and their safety procedures. Materials will be developed in English, Spanish, and other major languages for distribution through health clinics, hospitals, pharmacies, and online platforms, with a report to the Governor and Legislature due within 18 months.
