Journal ArticleDOI
A high incidence of species substitution and mislabelling detected in meat products sold in South Africa
TL;DR: Overall, this study confirmed that the mislabelling of processed meats is commonplace in South Africa and not only violates food labelling regulations, but also poses economic, religious, ethical and health impacts.
Journal ArticleDOI
DNA barcoding reveals a high incidence of fish species misrepresentation and substitution on the South African market
TL;DR: The existing legislation pertaining to seafood marketing in South Africa is inadequate or poorly enforced and requires urgent revision and DNA barcoding appears to hold great potential for fish authentication monitoring by both regulatory bodies and industry, the utilisation of which could enhance transparency and fair trade on the domestic fisheries market.
Journal ArticleDOI
Evaluation of the 16S and 12S rRNA genes as universal markers for the identification of commercial fish species in South Africa.
TL;DR: The nucleotide variation in both the 16S and 12S sequences was suitable for identifying the large majority of the examined fish specimens to at least the level of genus, but was found to be less useful for the explicit differentiation of certain congeneric fish species.
Journal ArticleDOI
Comparative study of different methods for the extraction of DNA from fish species commercially available in South Africa
TL;DR: Overall, the SureFood® PREP method was of the simplest and least hazardous to perform, extracting significantly more DNA than the other methods in terms of yield and purity.
Journal ArticleDOI
Establishment of a mitochondrial DNA sequence database for the identification of fish species commercially available in South Africa
TL;DR: The present study has established the necessary genetic information to permit the unambiguous identification of 53 commonly marketed fish species in South Africa, the applications of which hold a plethora of benefits relating to ecology research, fisheries management and control of commercial practices.
