Occurrence of microcystin congeners in surface waters and food in Belgium as a source of exposure to humans
cyanobacteria blooms among the global population in Belgium. There is a general concern about the negative impact of the blooms and their toxins on the environment and public health. Yet, limited data about ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
laboratories in the future. The method was first tested on minced beef spiked with shiga toxin-producing E.coli (STEC) at very low level (5 CFU /25g). After enrichment for 16 or 24 hours in buffered peptone ...
Simultaneous Detection and Quantification of Aflatoxin M1, Eight Microcystin Congeners and Nodularin in Dairy Milk by LC-MS/MS
(AFM1), an emerging mycotoxin of interest, is a potential contaminant in the milk of animals who ingest aflatoxin B1 (AFB1). The toxin is regulated in the European Union under Commission Regulation No ...
Development, Validation and Application of a Targeted LC-MS Method for Quantification of Microcystins and Nodularin: Towards a Better Characterization of Drinking Water
(ADDA) group connected to a peptide ring. However, NOD ’s ring contains five peptides, whereas the MC s have a heptacyclic peptide ring [13,14]. Both toxins inhibit protein phosphatase 1 (PPI) and 2A ...
A Summer of Cyanobacterial Blooms in Belgian Waterbodies: Microcystin Quantification and Molecular Characterizations
Source: Toxins, Volume 14, Issue 1 (2022) Keywords: analysis blooms Liquid Chromatography with tandem mass spectrometry (LC-MS/MS) Mass Spectrometry microcystin Monitoring planktonic cyanobacteria Abstract: ...
Quality of laboratory studies assessing effects of Bt-proteins on non-target organisms: minimal criteria for acceptability
risk assessment is not obvious. Applying a worst-case expected environmental concentration of bioactive toxins equivalent to that present in the transgenic crop, confirming exposure of the test species ...
