On August 12, 2019, AOAC INTERNATIONAL announced the adoption of an Official Method of Analysis℠ for determining the presence of free bisphenol A (BPA) in a broad range of still and carbonated bottled beverages, including soft drinks with sugar and caffeine, 100 percent orange juice with pulp, and whole milk.

The new method expands testing options by using liquid chromatography, a common analytical tool in many laboratories. The method was evaluated against Standard Method Performance Requirements (SMPRSM) 2017.018, which detailed analysis standards consistent with the increasingly conservative regulatory requirements for BPA such as those enacted in California.
