4. Conclusions
Chilean crab-meat commercial products generally do not inform taxonomic contents beyond stating that it corresponds to crab meat, and when informed (one source) it does not go to species level. According to the genetic authentication performed, mislabeling was detected in the source that declared a genus as contents; it included three species of different genera that differed from the one declared. Most commercial packages of crab-meat contain muscle tissue of more than one species, and most species detected belong to the family Cancridae. Thus, labeling is poor and very generic (crab-meat). The developed tool is based on amplifying and sequencing of DNA,DNA Barcoding, and phylogenetic analysis. It can be very useful to control of commercialized raw and processed products from Chilean brachyurans, authenticate protected species, verify the traceability of different crab batches along the commercial chain,establish correct labels, protect the consumer’s rights, stimulate fair competition among fishing operators, and assist fisheries control.
