Food Contact Materials (FCMs), such as plastics, papers, ceramics and inks used in food packaging, containers, kitchen utensils and tableware are subject to scrutiny due to their potential to release toxic compounds into food. In the European Union, materials and articles intended for contact with food must adhere to stringent safety regulations and novel materials not explicitly covered by existing legislation require individual risk assessment. This project focused on the assessment of the genotoxic potential of two substances used in FCMs, specifically neodecanoic acid (NDA) and di(2-ethylhexyl) phthalate (DEHP), for which data gaps have been identified in genotoxicity studies.

The purpose of this study is to evaluate, through analysis, the ability of older persons to retrieve items from kitchen cabinets. To achieve this goal, data were collected from 128 valid questionnaires and supplemented with field research and user interviews. The study revealed that the elderly's behavior in retrieving items from kitchen spaces is characterized by both high frequency and difficulty.

Article Synopsis
- Brominated flame retardants (BFRs) and organophosphate flame retardants (OPFRs) are widely used in electronics to prevent fires, but they pose serious health risks, including cancer and hormonal disruptions.
- A study analyzed 203 black plastic household products in the U.S. and found that 85% contained harmful flame retardants, with concentrations reaching up to 22,800 mg/kg.
- Products made from styrene-based plastics (common in electronics) had significantly higher levels of flame retardants compared to those made from polypropylene and nylon, raising concerns about potential exposure through everyday items like kitchen utensils.
Article Synopsis
- Kitchen equipment and processes can significantly contribute to microplastic contamination on our plates, beyond just food and packaging sources.
- This review examines how various utensils and cooking methods may release microplastics during food preparation, addressing a knowledge gap in existing research.
- The findings raise important concerns about food safety and potential health risks associated with microplastic exposure from everyday kitchen activities.
Selective atomic sieving across metal/oxide interface for super-oxidation resistance.

Surface passivation, a desirable natural consequence during initial oxidation of alloys, is the foundation for functioning of corrosion and oxidation resistant alloys ranging from industrial stainless steel to kitchen utensils. This initial oxidation has been long perceived to vary with crystal facet, however, the underlying mechanism remains elusive. Here, using in situ environmental transmission electron microscopy, we gain atomic details on crystal facet dependent initial oxidation behavior in a model Ni-5Cr alloy.
