American workers in agriculture, meatpacking, and warehousing face mounting health risks from extreme heat exposure, with this year marking the hottest summer on record in the nation. Despite the escalating climate crisis expected to intensify heat events, most workers in fields, greenhouses, and indoor facilities lack adequate heat protections mandated by law. Several workers have died from heat-related causes, including a 24-year-old harvesting sweet potatoes in Mississippi and a 47-year-old farmworker in Florida, while hospitals report increasing cases of heat-related kidney disease among outdoor workers in Texas.
Facing stalled government action at federal, state, and local levels, labor organizations are increasingly adopting a market-based enforcement model pioneered by the Coalition of Immokalee Workers. This approach targets the reputations of major brand-name retailers rather than smaller supply chain entities, pressuring companies to pay premiums for products from farms that comply with worker protection codes. Farms that violate the standards risk losing preferred buyer status, creating enforcement leverage without relying on government regulators. Groups including Miami-based WeCount have begun replicating this model across industries such as dairy production in Vermont, construction in Minnesota, and banana production in Ecuador.
Efforts to establish protections through traditional regulatory channels have repeatedly failed. A proposed Miami-Dade County ordinance that would have mandated paid rest breaks, water access, and first aid procedures when heat index reached 90 degrees was blocked by the Florida state legislature through preemptive state law. At the federal level, proposed Occupational Safety and Health Administration standards under the previous administration have stalled, with recently introduced legislation seeking to prevent their implementation. Union representatives argue that without enforceable federal standards, millions of workers remain vulnerable, particularly in meatpacking, poultry plants, and warehouses where environmental controls are inadequate.
The Coalition of Immokalee Workers, which has operated the Fair Food Program since the early 1990s, now protects workers across dozens of crop types and has begun expanding electrolyte access year-round on participating farms in response to intensifying heat conditions.
