This study was initiated following a 2018 E. coli O157:H7 outbreak linked to romaine lettuce from the Southwest growing region and represents one of the largest environmental microbiology research efforts to date. Multi-year environmental studies are designed to shed light on environmental conditions that could impact food safety. Having this kind of study helps reinforce the shared commitment to public health through research, science and continuous improvement to promote science-informed food safety practices.
California continues to remain engaged in food safety discussions through the diverse stakeholders represented by the California Agricultural Neighbors (CAN) efforts and by way of the California Longitudinal Study. While the study mentioned below is unique to the Southwest growing region, a One Health approach recognizes the health of people, animals and the environment are intertwined with the goal of achieving holistic health outcomes. You can learn more about California’s One Health efforts related to produce safety on the CDFA Produce Safety One Health Initiatives webpage.

Constituent Update
June 5, 2024
Today the U.S. Food and Drug Administration updated its website to share preliminary findings from a multi-year environmental study of a specific growing region within the Southwest growing region conducted in partnership with the Arizona Department of Agriculture, and in conjunction with the University of Arizona Cooperative Extension, the Wellton-Mohawk Irrigation and Drainage District (WMIDD), and members of the leafy greens industry. The study sought to better understand the ecology of human pathogens in the environment in the Southwest agricultural region, particularly how pathogens survive, move, and possibly contaminate produce prior to harvest, so that the agricultural community can work together to identify best practices to enhance food safety.
