Evidence of 3600 chemicals known to be used in food contact (packaging, cookware, etc) also detected in humans; ~25% of known food contact chemicals. Groups like bisphenols, PFAS are often tested while others like synthetic antioxidants & oligomers little is known of their presence or fate in humans

Original study: [Evidence for widespread human exposure to food contact chemicals](https://www.nature.com/articles/s41370-024-00718-2)

Studies investigating human exposure to the chemicals used in food contact materials, like packaging and cookware, generally focus on a few dozen chemicals of concern, such as bisphenols, PFAS, phthalates, mineral oil hydrocarbons, and heavy metals. However, thousands of chemicals are intentionally added during the manufacture of food contact materials and articles, and even more may be present in the final products. 

This study is a systematic overview of food contact chemicals that have been monitored and detected in human samples, such as urine, blood, and breast milk. In total, 3601 chemicals found in humans are either used in the manufacture of food contact materials or present in the final articles, such as packaging and kitchenware. This represents 25% of the more than 14,000 known food contact chemicals 

The presence of a food contact chemical in humans does not automatically mean that packaging or cookware was the exposure source since many of these chemicals are used in other products. However, this research helps to better understand the contribution of food packaging, cookware, processing equipment, etc. to overall human exposure to chemicals. Additionally, it highlights those chemicals that earlier studies have found to transfer out of food packaging but have never been investigated in human samples. 

All of the underlying data the study is built on are also publicly available (and searchable) via a [public dashboard](https://www.foodpackagingforum.org/fcchumon). (Note: the dashboard is a bit on the technical side)

TLDR – 25% of known food contact chemicals have evidence of being in people but whether food packaging, cookware, etc. is the main or only source is not known. Also, some chemicals measured transferring out of packaging have not been investigated in humans (yet).
