Catfish Masquerading as Cod in UK Chip Shops
1 May
Summary
- Catfish is sold as cod to cut costs, deceiving customers.
- DNA tests confirm catfish species sold in three takeaways.
- Consumers expect cod or haddock, not cheaper farmed fish.

Several chip shops have been caught mis-selling catfish as traditional fish and chips, a practice discovered through BBC investigations. Cases involve pangasius, also known as river cobbler, being sold without customers' full awareness. This cheaper, farmed fish from Southeast Asia costs approximately £3.40 per kilogram wholesale, a stark contrast to cod and haddock at around £15 per kilogram.
DNA barcoding tests at Liverpool John Moores University confirmed that three out of ten businesses sampled had sold catfish. While this fish is safe to eat, the deception lies in the mis-selling and the price point. Consumers often expect marine species like cod or haddock and are unaware they might be served a cheaper alternative. Trading Standards noted that while not widespread, unscrupulous businesses do exist.
Authorities are investigating, with the Food Standards Agency and local councils likely to address isolated cases. Consumers are advised to ask for the fish species if it is not specified on the menu. If they suspect deception, they should contact their local trading standards or environmental health teams. The practice raises concerns about consumer trust and fair competition within the industry.
