The Federal Trade Commission has requested information and documentation from a wide range of U.S. companies as part of a broad investigation of the supply chain.  Companies to participate  include Proctor & Gamble Company, Walmart Inc, The Kroger Company, Associated Wholesale Grocers, Tyson Foods, Kraft Heinz, Amazon.com Inc, C&S Wholesale Grocers among others. 

Companies must respond within 45 days detailing how they are responding to the problems in their respective supply chains, availability of transportation and pricing.  The FTC is also requesting suggestions for both resolution of existing problems and prevention of future difficulties.

The information requested is for the technical evaluation of the supply chain and is unrelated to any specific law enforcement investigation.
