Accurate estimates of foodborne disease rates are critical for understanding and improving global food safety. In preparation for an updated report on foodborne disease burdens, the World Health Organisation (WHO) has launched a new study to refine source attribution techniques, which help identify how various pathogens are transmitted through food. These insights are essential for targeting high-risk areas, improving food safety protocols, and effectively allocating limited resources to prevent illness.
One focus of the WHO’s study is understanding how pathogens move from farm to table. Since foodborne diseases are caused by multiple pathogens, such as bacteria and parasites, the WHO study aims to clarify how specific foods and environmental factors contribute to the spread. Tools like microbial subtype modelling and structured expert judgement allow researchers to gain a clearer picture of which foods are responsible for outbreaks. This level of detail helps regulatory bodies like the U.S. FDA prioritise interventions, making food safety efforts more effective and targeted.
WHO’s efforts include gathering data on foodborne outbreaks globally. While challenges remain — such as data gaps across different regions — using structured expert insights provides a globally consistent method for estimating foodborne disease risks. This approach will allow regulators to set better priorities and enhance food safety protocols, protecting consumers worldwide.
Accurate disease attribution is vital for food producers, who can use this information to implement stronger safety standards and achieve relevant certifications, such as ISO 22000 for food safety management.
