- Summary: On October 6, 2010, the FDA issued a Warning Letter to Thanh Son Tofu, Inc. following an inspection on April 15 & 16, 2010, which revealed serious violations of Current Good Manufacturing Practice (CGMP) regulations (21 CFR Part 110).

The company's response on employee training lacked sufficient detail.
