New Predictive Toxicology Publication

As part of Nick's work for the Food & Environment Research Agency, a paper on "Application of In Silico Modelling to Estimate Toxicity of Migrating Substances from Food Packaging" has been accepted for publication in the Journal of Food and Chemical Toxicology.

This study derived toxicity estimates for a set of  136 chemical migrants from food packaging materials using in silico (computational) modelling and read across approaches. Where available, the predicted results for mutagenicity and carcinogenicity were compared with published experimental data. As the packaging compounds are subject to safety assessment, the migrating substances were more likely to be negative for both the endpoints. A set of structural analogues with positive experimental data for carcinogenicity and/or mutagenicity was therefore used as a positive comparator. The results showed that a weight of evidence assembled from different in silico models and read-across from already-tested structurally similar compounds can provide a rapid and reliable means for rapid screening of new yet-untested intentional or unintentional chemical compounds that may migrate to packaged foodstuffs.
