 With these acquisitions, Kirima had positioned himself to be a major meat supplier for Nairobi.As chairman of the African Butchers Association (later the Kenya National Butchers Union), he successfully lobbied the government for permission to sell meat in the city, a privilege that was hitherto reserved for the still settler-controlled Kenya Meat Commission (KMC) which did not buy meat from African farmers.Kirima started a private abattoir in Njiru, a development that some believe led to the eventual collapse of the KMC years later.
