The World Health Organization (WHO) released a report on June 4, 2026, highlighting the global health burden caused by unsafe food. Each year, unsafe food is responsible for approximately 1.5 million deaths globally and sickens about 866 million people, the agency said [1].

The WHO analyzed data collected from 194 countries spanning 2000 to 2021 to produce these estimates [2, 3]. Director-General Tedros Adhanom Ghebreyesus said, "Food safety is not an abstract issue – it touches every meal, every family, every day" [1]. In Chinese, he stated, “食品安全并非抽象的概念，它与每一餐、每一个家庭、每一天都息息相关。” [2].

Children under five face a much higher risk. They have nearly three times the likelihood of contracting foodborne illnesses compared to other age groups and represent about one third of the total cases, despite making up only 9% of the global population [2, 1]. There is some variation in estimates, with one source reporting nearly twice the risk for children under five [3].

The bulk of illnesses come from biological hazards, including bacteria, viruses, and parasites. However, chemical contaminants such as inorganic arsenic and lead contribute disproportionately to deaths. These chemicals increase risks of cardiovascular disease and cancer [2, 1].

Geographically, Africa and Southeast Asia bear the greatest burden, accounting for about 75% of foodborne illnesses and roughly 60% of deaths linked to unsafe food [2, 3, 1].

The economic impact is significant as well. Adjusted for cost-of-living differences, productivity losses due to foodborne diseases were valued at $647 billion in 2021. An alternate figure of $310 billion unadjusted was also given [2, 1].

The WHO report underscores the scale and severity of food safety challenges worldwide. It draws on extensive data collected over two decades to provide a comprehensive view. Measures to reduce contamination and protect vulnerable populations, especially young children in high-risk regions, remain critical.

The WHO publication date is June 4, 2026, marking the latest global assessment of foodborne disease impact [1].
