Interesting consequence of the global supply chain (really, network). For every ingredient or process sourced from a different manufacturer or factory or farm, there's added difficulty in auditing quality and consistency, and a source of unwanted variation in the end product. It's feasible to comb over one factory to look for quality problems, but not for hundreds of suppliers around the world.
