The frequent occurrence of food safety incidents has aroused public concern about food safety and key contaminants. Foodborne pathogen contamination, pesticide residues, heavy metal residues, and other food safety problems will significantly impact human health. Therefore, developing efficient and sensitive detection method to ensure food safety early warning is paramount. The aptamer-based sensor (aptasensor) is a novel analytical tool with strong targeting, high sensitivity, low cost, etc. It has been extensively utilized in the pharmaceutical industry, biomedicine, environmental engineering, food safety detection, and in other diverse fields. This work reviewed the latest research progress of aptasensors for food analysis and detection, mainly introducing their application in detecting various key food contaminants. Subsequently, the sensing mechanism and performance of aptasensors are discussed. Finally, the review will examine the challenges and opportunities related to aptasensors for detecting major contaminants in food, and advance implementation of aptasensors in food safety and detection.

Use of immunomodulating agents to prevent the progression of autoimmune β-cell damage leading to type 1 diabetes mellitus (T1DM) is an interesting area for research. These include non-specific anti-inflammatory agents, immunologic vaccination and anti-inflammatory agents targeting specific immune cells or cytokines. Teplizumab is an anti-CD3-molecule that binds to and leads to the disappearance of the CD3/TCR complex and rendering the T cell anergic to its target antigen.

The additive is already authorised as sensory feed additive for use in feed for chickens for fattening, minor poultry species for fattening, laying poultry, poultry reared for laying, ornamental fish, ornamental birds and ornamental breeder hens. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concludes that canthaxanthin produced with CBS 146148 is considered safe for the target species, the consumer and the environment under the current authorised conditions of use.

As a follow-up to this assessment, the FAF Panel was requested to assess the safety of citric acid esters of mono- and diglycerides of fatty acids (E 472c) for its use as food additive in food for infants below 16 weeks of age belonging to food categories (FCs) 13.1.

The context of the peer review was that required by Regulation (EC) No 1107/2009 of the European Parliament and of the Council. The conclusions were reached on the basis of the evaluation of the representative use of lysate of C2c Maky as a fungicide against downy mildew () on grapevines and table grapes.

The NF is a mineral salt that consists mainly of magnesium potassium trichloride hexahydrate. The information provided on the composition is sufficient for characterising the NF and does not raise safety concerns.
