What is HARPC? HARPC stands for âHazard Analysis and Risk-Based Preventive Controls.â It is one of many new provisions of the FDA Food Safety Modernization Act, a sweeping food safety legislation amending the Food, Drug and Cosmetic Act that was enacted in January of 2011.
Choletec (BrIDA, MEB, Mebrofenin) is a carrier for the radioactive Tc-99m that makes it go straight to the organ of interest. The Choletec conjugate is not dangerous by itself; only the Tc-99m matters in terms of breastfeeding safety. The radioactive half-life of Tc-99m is fixed at 6 hours and is entirely independent of any influence by Choletec. The International Commission on Radiological Protection (ICRP) and the American Academy of Pediatrics do not specifically mention Choletec in their breastfeeding safety recommendations for Tc-99m.
