This episode of Food Safety Five discusses a new study that leverages a novel quantitative microbial risk assessment (QMRA) model that suggests that half of E. coli O157:H7 illnesses linked to romaine lettuce are caused by contamination via untreated overhead irrigation water.
England saw a 26 percent rise in Shiga toxin-producing Escherichia coli (STEC) infections from 2023 to 2024, and non-O157 STEC cases tripled since 2019. These trends may be driven by one foodborne illness outbreak involving contaminated salad leaves.
The International Fresh Produce Association (IFPA) is reorganizing its organizational structure to enhance and amplify its produce safety and food safety regulatory goals.
Western Growers and FDA have signed a Memorandum of Understanding (MOU) to improve fresh produce safety and prevent foodborne illnesses through a new data-sharing framework. The MOU is aligned with the Reagan-Udall Foundation’s recently published Roadmap to Produce Safety report.
The Reagan-Udall Foundation for FDA has published a report based on months of stakeholder dialogues, titled, the Roadmap to Produce Safety, which provides recommendations for a private sector-led collaborative to improve U.S. produce safety.
Using a newly developed quantitative microbial risk assessment (QMRA) model, researchers have identified interventions along the U.S. romaine lettuce supply chain that would most effectively reduce E. coli contamination. The QMRA is publicly available for use.
The European Food Safety Authority (EFSA) has published a report that investigates the occurrence of 21 active substances frequently detected on organic products that are approved for use in plant protection products, but are not allowed in organic food production.
The Environmental Working Group’s (EWG’s) 2025 Dirty Dozen list considers pesticide toxicity for the first time. While critics say the list is alarmist and may discourage the consumption of safe fruit and vegetables, EWG argues that “legal does not mean safe” when it comes to pesticide residues.
Reflecting on 20 years of research, scientists from the University of Pretoria and the Water Research Commission in South Africa are calling for better national water quality standards, as well as regular surveillance and testing of water sources and produce, to address contaminated irrigation water and improve produce safety.
