A shotgun metagenomics approach to detect and characterize unauthorized genetically modified microorganisms in microbial fermentation products
study, this approach was performed on a case with a previously isolated and sequenced GMM, an unresolved case for which no isolate was obtained, and a non‐ GMM ‐contaminated sample, all repre- sentative ...
Optimization and validation of an analytical method for the quantification of short- and medium-chained chlorinated paraffins in food by gas chromatography-mass spectrometry
Fractionation using silica cartridges efficiently removed a number of potentially interfering halogenated compound classes from sample extracts while retaining 96% of ∑ SCCP s and 99% of ∑ MCCP s. Limits of ...

High abundance and diversity of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in faeces and tonsils of pigs at slaughter.
(2017) Abstract: This cross-sectional study investigates the abundance of cefotaxime-resistant Escherichia coli (CREC) in the faeces and tonsils of 96 pigs during slaughter. Moreover, different isolates ...
A more sensitive, efficient and ISO 17025 validated Magnetic Capture real time PCR method for the detection of archetypal Toxoplasma gondii strains in meat.
demonstrated. For this, a bioassay is still the reference method. As an alternative, various PCR methods have been developed, but due to the limited amount of sample that can be tested, combined with a low tissue ...
Development and performance assessment of a luminex xMAP® direct hybridization assay for the detection and identification of indoor air fungal contamination.
monitored using classical protocols based on culturing. However, this culture dependency could influence the representativeness of the fungal population detected in an analyzed sample as this includes the ...
Assessment of dietary intake of 10 intense sweeteners by the Italian population.
Labeling Humans ITALY Sweetening Agents Abstract: The aim of the present study was to monitor the consumption of foods containing intense sweeteners present on the Italian food market and to investigate ...
