Hazard characterization of Alternaria toxins to identify data gaps and improve risk assessment for human health.

of structurally diverse secondary metabolites with toxic potential has been identified, but occurrence and relative proportion of the different metabolites in complex mixtures depend on strain, ...

Linking nanomaterial-induced mitochondrial dysfunction to existing adverse outcome pathways for chemicals.

(AOP) framework plays a crucial role in the paradigm shift of toxicity testing towards the development and use of new approach methodologies. AOP s developed for chemicals are in theory applicable to ...

Persistence of the Staphylococcus aureus epidemic European fusidic acid-resistant impetigo clone (EEFIC) in Belgium.

encoding the Panton-Valentine leucocidin, the toxic shock syndrome toxin and the exfoliatins A and B. MLST clonal complexes were deduced from the spa types. RESULTS: Among the 518 S. aureus strains analysed, ...

Whole-Genome Sequencing-Based Screening of MRSA in Patients and Healthcare Workers in Public Hospitals in Benin.

virulence genes, including the genes encoding the Panton-Valentine leukocidin toxin (48.15%, n = 13/27), and the gene (29.63%, n = 8/27), associated with toxic shock syndrome. This study highlights the need ...

Simultaneous Detection and Quantification of Aflatoxin M1, Eight Microcystin Congeners and Nodularin in Dairy Milk by LC-MS/MS

among infants and children. However, it is crucial to address the presence of multiple natural toxic compounds that may co-occur in dairy milk to ensure its safety prior to consumption. Aflatoxin M1 ...

Application of silver-based biocides in face masks intended for general use requires regulatory control

control SARS-CoV-2 infection needs to be balanced against possible toxicity due to inhalation exposure. Direct measurement of silver (particle) release to estimate exposure is problematic. Therefore, this ...

Regulatory safety assessment of nanoparticles for the food chain in Europe

Keywords: Integrated approaches to testing and assessment (IATA) nanomaterial particulate material Physicochemical characterisation Risk Assessment Toxicity testing Abstract: Background The risk assessment of ...

Pesticides, trace elements and pharmaceuticals in tea samples available in Belgian retail shops and the risk associated upon acute and chronic exposure

residue level (MRL) set by the EU. However, further risk assessment, based on the values of pesticide residues and the toxic trace elements encountered in the brew, demonstrate that the consumption of these ...

Cyanotoxins and Food Contamination in Developing Countries: Review of Their Types, Toxicity, Analysis, Occurrence and Mitigation Strategies

countries. In this context, we present an up-to-date overview of cyanotoxins (types, toxic effects, analysis, occurrence, and mitigation) with a special focus on their contamination in (sea)food from all the ...

Assessment of information as regards the toxicity of T‐2 and HT‐2 toxin for ruminants

Ruminants toxicity T‐2 toxin Abstract: In 2011, the EFSA Panel on Contaminants in the Food Chain (CONTAM) adopted a Scientific Opinion on the risks for animal health related to the presence of T‐2 (T2) and HT ...
