The first laws that penalized food
and drug adulteration is the The Adulteration of Food and Drugs Act 1860, which

people have to pressure the government to pass anti-adulteration laws to reduce
absenteeism of their workers. The laws outlawed a lot of adulteration practices
and also made provisions for appointments of public analysts to inspect food
and drugs.
