Minimising legionella in the water at a Hungarian pharmaceutical plant

This Hungarian pharmaceutical plant was part of a worldwide pharmaceutical group. In France, where the group has its headquarters, Legionella issues are regulated by a national legislation with provisions stricter than those in Hungary. The company decided to apply the French provisions regarding Legionella in Hungary as well. Legionella monitoring revealed high-risk spots in the hot water circulation system. The company cleaned the piping and introduced regular heat-shock treatment. It also set up a new company water management plan, including cooling water. The standard company approach helped to tackle Legionella risk and has prevented diseases so far.
