Butter is without any question the most counterfeited food. This was the opening sentence at the symposium in Brussels in 1888 and while butter may not be the most counterfeited food today, the authenticity and quality of butters and margarines on sale today still come into question.

Back in the late 1800s, analytical chemists and control authorities were concerned that chalk and potato starch was used to bulk out butter, increasing the quantity and boosting profits for the seller. After margarine appeared on the market, sellers would also try to sell margarine as if it was butter as well as mixing much cheaper margarine into the butter.
