South African food is clear of horse meat contamination, but it does have water buffalo, donkey and goat meat in mislabelled products.
A study by three professors at Stellenbosch University found 99 of 139 samples contained species not declared in the product label, with the highest incidence in sausages and beef burgers.
"There's a fair share of fraudulent meat products on the South African market, according to a new study by meat scientists from Stellenbosch University," the university reports on its blog.
The study found soya, donkey, goat and water buffalo was found in up to 68 percent of the minced meats, burger patties, deli meats, sausages and dried meats that were tested.
Undeclared plant matter was also detected.
These ingredients were not declared on the products’ packaging labels.
The study was published in the international Food Control journal.
Co-author Professor Louwrens C Hoffman said: "This study confirms 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."
He confirmed no horse meat was found.
On Monday, Swedish company Ikea withdrew meatballs from sale in 14 European countries after tests in the Czech Republic found traces of horsemeat in a batch made in Sweden.
