Is there confidence in the testing method using the HNS-system (human nose)?

In the Netherlands, many studies have been carried out to confirm the reliability of the HNS system to determine a different odor. The Dutch retail is satisfied with the method. The method has already proven its reliability for several years.
Slaughter houses are mainly worried that their customers reject boar meat in advance. It is mainly an emotional resistance and perception to boar meat. Not against the control method as such.
