Research by the Dutch Consumers' Association (Consumentenbond) shows that three years after the horse meat affair are still many problems with the authenticity of foodstuffs. The Consumentenbond investigated over 150 sensitive products, and 21% of them were not how they were described. The samples were analysed using the most up to date methods.
The study found problems with the following percentage of samples taken: manuka honey (50% ), lamb (47%), extra virgin olive oil (31% ), oregano (11% ) and cod (3%).
In the lamb products study, 10 lamb curries, 10 servings of minced lamb and 10 lamb shawarma or kebabs were purchased. 14 of the 30 lamb samples turned out not to be pure lamb. In 6 samples, there was no lamb found at all, only beef or turkey instead. In 8 other samples there was some lamb, but also at least 40% of other meat.
