From the September 1904 issue of the Socialist Standard
“Adulteration is a legitimate form of competition.”—John Bright.
The proud distinction of having beaten all previous records in the fine art of butter adulteration probably belongs to a Burnley grocer, who succeeded in selling as butter a composition in which there was only 1 per cent of the genuine products of milk. All the rest was "foreign fat.” There were previous convictions, and he has had to pay heavily for his final proficiency. A contemporary referring to the case cannot help asking “Why the 1 per cent.?” Is it chemistry or is it conscience which demands it ? —“The Co-operative News.”
