“…All these questions have stimulated interest in the establishment of reliable tracing systems that can assure the quality and authenticity of produce, as well as consumer confidence. 1,4 One example of the need for reliable tracing is the tambaqui, Colossoma macropomum (Cuvier, 1818), a fish native to the Amazon and Orinoco basin, which is the native Brazilian fish most farmed in the country. 5,6 The intense exploitation of the wild stocks of this species resulted in a drastic decline in the numbers adult individuals in the wild environment, and the inclusion of the species in the official list of overfished species.…”

BACKGROUND In recent years, tracing of alimentary produce of animal origin has become increasingly important, for economic, food safety and ecological reasons. The tambaqui, Colossoma macropomum, is the native fish most farmed in Brazil. The reliable identification of the origin of tambaquis (wild or farmed) offered for sale to the general public has become necessary to satisfy regulatory norms and uphold consumer confidence. Molecular methods based on the analysis of DNA sequences have often been used to evaluate the potential for tracing farmed fish, given their reliability and precision. RESULTS Full likelihood and Bayesian approaches proved to be the most efficient for the identification, respectively, of individuals and populations for most of the fish sampled from seven hatcheries and one wild stock. The exclusion method and genetic distances were the least effective approaches for the identification of individuals and populations. The Bayesian method identified correctly more than 99% of the fry from most stocks, except those of the Santarém hatchery and River Amazon wild stock, which presented the best results for individual identification. CONCLUSIONS The identification of populations was effective for most hatcheries, although the identification of individuals from most stocks was hampered by the reduced genetic variability. © 2018 Society of Chemical Industry

“…Figure 1 shows that DNA barcoding became a keyword in the scientific literature since 2000, hence it must be considered a very recent topic in the research field around the world. Applications of DNA barcoding to food safety and food piracy issues have grown in importance due to the consumers' increasing attention to food authenticity and food safety in different products and species [24][25][26][27]. This interest seems to be due to the consumers' lack of confidence, in particular towards food of animal origin, and it is attributable to several reasons including both food safety and socio-economic changes.…”

DNA barcoding is a molecular technology that allows the identification of any biological species by amplifying, sequencing and querying the information from genic and/or intergenic standardized target regions belonging to the extranuclear genomes. Although these sequences represent a small fraction of the total DNA of a cell, both chloroplast and mitochondrial barcodes chosen for identifying plant and animal species, respectively, have shown sufficient nucleotide diversity to assess the taxonomic identity of the vast majority of organisms used in agriculture. Consequently, cpDNA and mtDNA barcoding protocols are being used more and more in the food industry and food supply chains for food labeling, not only to support food safety but also to uncover food piracy in freshly commercialized and technologically processed products. Since the extranuclear genomes are present in many copies within each cell, this technology is being more easily exploited to recover information even in degraded samples or transformed materials deriving from crop varieties and livestock species. The strong standardization that characterizes protocols used worldwide for DNA barcoding makes this technology particularly suitable for routine analyses required by agencies to safeguard food safety and quality. Here we conduct a critical review of the potentials of DNA barcoding for food labeling along with the main findings in the area of food piracy, with particular reference to agrifood and livestock foodstuffs.

“…The authors concluded that several factors including strong genetic differentiation, polymorphism, number of reference samples per population and number of loci are affecting the outcome of assignment tests (BEKKEVOLD et al, 2015;GLOVER et al, 2009;HOWARD et al, 2009;MANEL et al, 2005;MAUDET et al, 2002). Also, the use of Bayesian clustering analysis to identity gene pools can substantially improve the accuracy of genetic assignment (BEKKEVOLD et al, 2015;GLOVER et al, 2009;MANEL et al, 2005;MATEUS and RUSSO-ALMEIDA, 2015) but identification at the stand level, as required for seed harvests, might be in this case not possible. Clustering analysis would therefore only be the method of choice for traceability at a regional level.…”

Traceability of forest material has received recently increasing interest and European regulations already apply on forest reproductive material and timber. DNA fingerprinting methods allow identification of species and control of geographic origin, providing that genetic reference data is available. In this review, we focus on the two economically important European oak species, Quercus robur and Q. petraea. We describe the available molecular markers and data, and discuss their applicability for traceability systems of forest reproductive material at a European scale. We also provide insights on the use of DNA fingerprinting on timber material.
