Monitoring of essential and toxic elements in multi-ingredient food supplements produced in European Union

The market of food supplements (FS) in European Union (EU) is on the rise. The present study investigated the content of essential (Ca, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Zn) and toxic elements (Cd, Cr(VI), Ni and Pb) in 168 FS produced in the EU and designed to support various health aspects (nutrition, neurological function, reproduction, weight loss, cosmetic appearance). The...

Höchstmengen für Vitamine und Mineralstoffe in Nahrungsergänzungsmitteln

In Deutschland greift etwa ein Drittel der Erwachsenen regelmäßig zu Nahrungsergänzungsmitteln (NEM). Neben Vitaminen und Mineralstoffen enthalten die Produkte teilweise auch sonstige Stoffe mit physiologischer Wirkung wie Aminosäuren, Fettsäuren, Pflanzenextrakte oder Mikroorganismen. Die Werbung verspricht positive Effekte für Gesundheit, Wohlbefinden und verbesserte Leistungsf...

Efficient estimation of the limit of detection and the relative limit of detection along with their reproducibility in the validation of qualitative microbiological methods by means of generalized linear mixed models

The reproducibility of measurement results is a core performance characteristic for quantitative methods. However, in the validation of qualitative methods it is not clear how to characterize a method’s reproducibility. One approach for determining a qualitative method’s reproducibility is presented for microbiological methods, where the distribution of colony forming units (CFU...

Gene drives do not always increase in frequency: from genetic models to risk assessment

Homing genes encode endonucleases that make a double stranded break in the DNA, destroying a target site on the homologous chromosome. When the cell repairs the break the homing allele is copied, converting a heterozygote into a homozygote. This results in gene drive (GD), an overrepresentation of the homing allele in the next generation. GD may propel CRISPR-Cas9 genes and new...

Food Fraud Kongress: Interaktiver Fachaustausch zur Bekämpfung von Lebensmittelbetrug in Deutschland und Europa

„Food Fraud“ war das Motto der gemeinsamen Veranstaltung des Bundesamts für Verbraucherschutz und Lebensmittelsicherheit (BVL) und des Joint Research Centers (JRC) der Europäischen Kommission am 12. und 13. Juni 2017 in Berlin. Im Zentrum des Kongresses stand die Revision der EU-Kontrollverordnung, die im Frühjahr 2017 in Kraft getreten ist. Diese neue rechtliche...

Vergleich der Testung von Sonnenschutzmitteln durch Stiftung Warentest und Öko-Test

The results of Stiftung Warentest, ÖKO-TEST and the official control laboratories are poorly comparable because of their different objects, even if there are some overlaps. Given the example of cosmetic sunscreen products, which had been tested by all 3 institutions over several years, the differences in testing and evaluation are presented. We show that also the testings of the...

Sanitising wooden boards used for cheese maturation by means of a steam-mediated heating process

The aim of this study was to describe the development and evaluation of a steam-mediated heating process for the sanitation of wooden boards used in cheese production. Wooden spruce fir boards from a cheese ripening centre were cut into small blocks and consecutively inoculated with suspensions of Listeria innocua at surface concentrations of 104 and 102 CFU/cm2, respectively...

Detection and isolation of Shiga-Toxin producing Escherichia coli in flour in Germany between 2014 and 2017

Official control samples of wheat and rye flour were analyzed for the presence of Shiga-toxin producing Escherichia coli (STEC) in 25 g. The detection procedure was based on enrichment in buffered peptone water and Tryptone Bile X-Glucuronide agar, followed by multiplex real-time PCR with an internal positive control. Positive samples were sub-cultured for strain isolation by a...

§ 64 LFGB Kick-off Meeting zu „Anwendungspotenzial moderner Analysetechniken im Bereich Lebensmittel- und Futtermittelsicherheit und deren Authentizität“

The area of food and feed analysis has been benefiting from related disciplines by using modern analytical techniques. However, corresponding standardization concepts are not yet available for the routine application of these methods. In order to meet the requirements of the official authorities responsible for food monitoring, it is requested to validate and to transfer these...

Wissenschaft im Spannungsfeld zwischen öffentlicher Wahrnehmung und wissensbasierter Politikberatung

Eine wissensbasierte Politikberatung sollte auf den Prinzipien Unparteilichkeit, Glaubwürdigkeit und Vertrauen beruhen. Die Erreichung dieser Ziele kann dabei nicht per se als gegeben vorausgesetzt werden, sondern erfordert die aktive Umsetzung einer einheitlichen Strategie der politikberatenden Institution. Die entsprechende Strategie des Bundesinstituts für Risikobewertung (BfR...

Gemeinsamer nationaler Bericht des BVL und RKI zu lebensmittelbedingten Krankheitsausbrüchen in Deutschland, 2015

In Deutschland werden jedes Jahr Hunderte von Krankheitsausbrüchen registriert, die über mikrobiell kontaminierte Lebensmittel verursacht wurden. Die Daten zu lebensmittelbedingten Ausbrüchen werden von den Gesundheits- und Lebensmittelüberwachungsbehörden vor Ort erfasst und über zwei parallele Meldewege (Übermittlung nach dem Infektionsschutzgesetz bzw. BELA-Meldungen) über die...

Screening for six genetically modified soybean lines by an event-specific multiplex PCR method: Collaborative trial validation of a novel approach for GMO detection

This study presents a novel approach to detect genetically modified (GM) plant events that are not covered by common GMO screening methods. It is based on a simplified multiplex assay which merges the event-specific real-time PCR methods for the detection of six GM soybean lines (MON 87701, MON 87708, MON 87769, DP-305423, CV-127 and DAS-68416). The use of two different...

Enterohemorrhagic Escherichia coli (EHEC) in water from karst springs: detection with real-time PCR and isolation of strains

Within 2 months, two water sources in a karst area in Switzerland were sampled 9 times each, and analyzed by real-time PCR for 6 EHEC O-types, Shiga-like-toxin (stx1 and stx2) and intimin (eae) genes. With the exception of O111, 5 O-types were recorded regularly and at high frequencies (O26: 33.3 %; O157: 33.3 %; O104: 66.6 %; O103: 72.2 %; O145: 94.4 %). Genes for Shiga-like...
