Pacific Harvest is the highest quality rice flour you can buy. And there is a lot of rice flour out there! When you buy rice flour produced in China, you then get into the issue of different standards. In China, wheat-free rice flour could be produced at a place that also produces wheat, and cross contamination may occur. This rice flour is perfect for those who can’t tolerate even a trace of wheat (e.g. those with Celiac disease), because it is all that is processed in the facility. And it has every food level certification possible.
