Rogue fish sellers are operating door-to-door in Rougham, near Bury St Edmunds, it has been reported to Suffolk Trading Standards.

The traders travel nationally and cold call homes, targeting vulnerable consumers using high pressure sales techniques.

Suffolk Trading Standards said: “These traders travel nationally, cold calling consumers’ homes selling the fish.

“This is often misdescribed, mislabelled or unlabelled, overpriced and sometimes underweight. They usually use Transit-style vans which are not refrigerated.

“Our advice is not to purchase, and to report the sellers to us on 03454 040506.”

The advice follows a Suffolk Trading Standards warning yesterday over ‘Nottingham Knockers’ operating in the Holbrook area.

A post on the Suffolk Trading Standards Facebook page said: “These individuals knock at doors and claim to be ex-convicts attempting to mend their ways, before trying to sell the householder everyday household products at very high prices.”
