African swine fever has not yet arrived in France but it is or has been circulating in several neighbouring countries. It is therefore important to know how this disease could spread if cases were detected in this country. Scientists from ANSES recently modelled its circulation in wild boar populations in two different parts of France. Their results highlight the importance of considering the topography of the landscape and of stopping hunting if the disease is detected.

Conventional methodologies are not always suitable for assessing the potential health risks to consumers of nanomaterials used in food. In 2021, ANSES therefore proposed a "nanospecific" risk assessment methodology, which it has just tested on the food additive E171, or titanium dioxide (TiO2), which is the most widely studied nanomaterial. Its use in food has been prohibited in Europe since August 2022. This practical application has shown both the method's validity and the extent of the lack of data for conducting an adequate risk assessment of nanomaterials in food.

ANSES undertook a new expert appraisal on the risks associated with exposure to chlordecone in the French Caribbean population. It confirmed that these risks can be significantly reduced by complying with all of the Agency's recommendations on the consumption of certain foods acquired via informal channels. Moreover, to avoid the contamination of home-produced eggs in particular, the Agency recommends stepping up membership in the JAFA family garden programme.
