If one intends to build quality into one's products, as is always wise and often required by law and regulations, then taking steps to confirm that ingredients or products are made correctly or are not contaminated should be a routine part of your quality program. This is so regardless of where you get your ingredients or products.
What may be overlooked here is that many Chinese products are of excellent quality and reliability, even as some are not. The real lesson from these recent events goes beyond China, however, and serves as a useful reminder of the importance of quality assurance measures in any packaging or manufacturing operation.
