Longtime Associated Press reporter Martha Mendoza will talk about “Seafood From Slaves,” her Pulitzer Prize-winning investigation of slavery in fishing. More than 2,000 slaves are free today because the AP put a spotlight on their misery. These men were captives of Thailand’s seafood industry, in some cases for decades, whipped with stingray tails if they asked for rest, risking murder by captains. They were forced to catch or process seafood that then made its way into the supply chains of almost every major U.S. food retailer, and to dinner tables worldwide.
