Rancid Ross

Bought a packet of Ross Sweet potato crisps from a padstal on 20 Aug 2025. When I opened the packet I immediately smelled rancid oil. The crisps were inedible and tasted rancid. I contacted Laastedrif the same day and Cillie informed me 3 days later they tested the batch and the oil was not rancid. The crisps were still wet when they were packed and sealed! How is that for food safety, maybe I should have checked for mould? They accepted no responsibility for the crisps that were not edible. Needless to say – stay away from this brand.
