To establish the results of the Environmental Health Policy of the city of Manizales from 2010-2016. Methods: An ex-post evaluation of the components of the action plan of the policy: basic sanitation and potable water, basic sanitation and waste management, hydric resource, monitoring inspection and the control of the consumption risks, food, zoonoses, diseases transmitted by vectors, air, noise and safe and healthy habitat; all theses were registered in an Excel page. Testimonies about the formulation and the implementation of the public policy obtained through a semi structured interview were included. Results: The results of the action plan reveal that the products of the policy were only the ones that corresponded to the fulfillment of the mission objectives of each participating institution and did not involve the environmental health policy. This was also reflected in the absence of the policy in the City Development Plan. To this is added the lack of economic resources, weak management by the directors of the institutions and a lack of continuity of the public officials whose positions are subjected to the change of government. Conclusions: The absence of an interinstitutional and intersectorial planning process for the implementation, monitoring and evaluation of a policy gave rise to processes, rather sessions, disjointed from the purposes, goals and objectives formulated.
