Supermarkets need to take an industrywide look at the supply chain to find suppliers that use improper labor practices, including human trafficking, says Carl Graziani, Safeway's senior vice president for supply chain. "As an industry, we need to think about how we can do this collectively," he said at the Supply Chain Conference. "Individually, it's a monumental task." Safeway is among supermarkets required by California to disclose efforts to eliminate human trafficking within their supply chain. Graziani suggests an industrywide method of information sharing to make the task easier.
