Guidelines for the validation of DNA extraction methods especially in the scope of the analysis of genetically modified sequences in food and feed products by real-time polymerase chain reaction (real-time PCR) are described. Performance testing of extracted DNA is primarily done by determination of the quantity and quality of amplifiable DNA in real-time PCR. Assessment of quality of extracted DNA includes determination of DNA concentration (e.g. fluorimetrically) and evaluation of fragmentation status by gel electrophoresis. A detailed procedure for in-house validation as well as subsequent inter-laboratory validation studies of DNA extraction methods is presented. © 2014 Bundesamt für Verbraucherschutz und Lebensmittelsicherheit (BVL).

As part of monitoring the placing on the market of plant protection products, samples are taken from the market by the competent authorities and by holders of authorisations and parallel import permits, and are examined for identity. The issue is whether the composition of a sample is identical to the composition stated in the application for authorisation and whether the physical, chemical and technical parameters correspond with the specification stipulated by FAO/WHO. The status described by Vinke (2009) concerning the assessment of the identity of plant protection products has undergone a thorough revision. Above all, criteria are described for assessing the results of studies on plant protection product samples. The revision was accomplished by the German-speaking working group for plant protection product analysis (DAPA) and the German-speaking working group for plant protection product formulations (DAPF). © 2014 Bundesamt für Verbraucherschutz und Lebensmittelsicherheit (BVL).

Ten years after publication of the White Paper on Food Safety, health consumer protection has made significant progress and, today, is a key field in politics at both the European and German levels. In addition to the protection of health and security of consumers, consumer information has become a core element of consumer protection for the Federal Office of Consumer Protection and Food Safety (Bundesamt für Verbraucherschutz and Lebensmittelsicherheit, BVL). State authorities are provided with new means of communication and interaction with consumers. © 2010 Springer Medizin Verlag. Source

Gene flow is the introduction of genetic material from one population of a plant species to another, thereby changing the composition of the gene pool in receiving plant population. Interacting populations in the Genus Beta are within the species B. vulgaris, B. macrocarpa, B. atripicifolia and potentially also B. trigyna. Genetic material from sugar beet to wild or weed beet populations can be introduced via pollen, seeds or feralization of the cultivar. Human activities like seed production and seed trade contribute substantially over long distances to the amount of naturally occurring gene flow. Best management options to decrease unintended gene flow are bolter control in root production fields, and isolation distances in seed production areas. © 2011 Society for Sugar Research & Promotion.

At the end of 2011, genetic modifications in Basmati rice were discovered for the first time in products placed on the European Union market. The products originated from Pakistan or India. In the EU, no event of genetically modified rice is approved as food or feed. The samples were initially identified by positive PCR screening results. Some of the detected genetically modified DNA sequences were previously identified in insect-resistant rice varieties originating from Asia. In addition to a sequence coding for a cry1Ab/Ac gene driven by the maize ubiquitin promoter, the integration of a 35S CaMV promoter-driven cry2A gene was detected. This is the first notification of the presence of a cry2A gene in Asian rice products in the EU. © 2013 Springer-Verlag Berlin Heidelberg. Source
