To summarize the experiences on the assurance of food hygiene security for the task forces in plateau earthquake areas in order to provide basis for health and logistics support of military troops carrying out diversified tasks. On the basis of food hygiene survey in the disaster areas and the surveillance on earthquake relief task forces, critical control points for food hygiene were identified. A comprehensive surveillance was pertinently done as follows: ⑴ Improving the knowledge on preventing altitude diseases and natural focus diseases (such as plague). the ability of self protection was improved generally through propagation and education; ⑵ Improving the knowledge on the importance of food hygiene for earthquake relief task forces to ensure the quality of food hygiene surveillance; ⑶ clarifying responsibilities and undertaking responsibilities level by level to make the surveillance activated; ⑷ combining the plateau environment features with the practical situation of task forces to formulate food hygiene security systems; ⑸ checking all procedures of food procurement, transportation, processing and storage strictly. ⑹ setting up an emergency system linking military and local units for food hygiene surveillance. Based on the above comprehensive supporting measures, no emergency related to food hygiene has happened in plateau earthquake relief task forces. Combining the characteristics of plateau environmental medicine with the practical situation of task forces to take specific measures, the food hygiene safety in the task forces could be ensured.
