Supermarket Shock: Crisis in America's Food Supply

CNBC takes a deep look at the links in the supply chain–how it works and how it’s coping during the pandemic. We meet people at every step of the way who are putting themselves at personal risk to keep that supply moving--from factory and farm to wholesaler and retailer. As COVID-19 spread, that chain became tested nationwide as it never has before. Faced with uncertainty, customers in the U.S. started to panic-buy at supermarkets and wholesale stores, and shelves of certain products emptied out. Fear of contracting the virus dramatically changed how Americans shop, as millions turned to online ordering, store pickup or home delivery for the first time. CNBC documents this story over several weeks of the nation's crisis.
