Rural California Report

In most jobs, if you have to spend even part of your workday exerting yourself under the hot summer sun, you’re likely to have drinking water nearby. And, if you don’t, you probably won’t be penalized for going to find some. But for many farmworkers in California, the largest agricultural producer in the country, the freedom to hydrate isn’t always so straightforward.

Even as temperatures climb above 90 degrees F, many of the state’s 400,000 farmworkers don’t have access to shade; or the water station is too far from where they are picking a crop, and they have to put off getting a drink. And since farmworkers are so frequently paid on a piece-rate basis rather than hourly, there’s strong incentive to put off that drink, if available at all, for as long as possible.

The San Joaquin Valley is the agricultural powerhouse of the United States and California. California accounts for an eighth of U.S. farm sales, largely because it produces high value fruit and nut, vegetable and melon, and horticultural specialty (FVH) crops such as nursery products and flowers. Over three-fourths of the state's $37 billion in farm sales in 2010 were crop commodities, and almost 90 percent of the $28 billion in California crop sales represented labor-intensive FVH commodities.

About half of California's farm sales and farm employment are produced in the eight-county San Joaquin Valley with four million residents that stretches from Stockton in the north to Bakersfield in the south. The leading U.S. farm county is Fresno, which had farm sales of almost $6 billion in 2010.

There are many heat stress prevention strategies for farmworkers that focus on correcting either individual behaviors (e.g., avoiding caffeinated beverages and bulky sweatshirts) or workplace conditions (e.g., providing shade and regular break periods). Yet, few heat stress-specific health plans take into consideration the conditions of the built and natural environment that farmworkers are returning to at the end of a long day in the fields.

Farmworker Interviews Reveal Heat Stress Illness

Risk Factors at Home

With funding from University of California Sustainable Agriculture Research and Education Program, researchers at UC Davis and the California Institute for Rural Studies (CIRS) recently partnered with the Organizacion de Trabajadores Agricolas de California (OTAC) to conduct interviews with farmworkers in the Stockton area. We hoped to learn more about the off-farm environmental factors that could contribute to the risk for heat stress illness among farmworkers. The interview results will assist the research team in identifying household and community factors that may contribute to heat stress illness in farmworker communities.
