Health security measures of food and drinking water during military training on the plateau / 军事医学

ABSTRACT

Objective To investigate the health security requirements on food and drinking water during military training on the plateau,and explore ways to improve military health security support capability.Methods Seven army units were randomly chosen.By means of on-site check and sample detection,both internal and external environmental factor changes and health and safety conditions of food and drinking water were surveyed on the plateau.Internal and external standard methods were used to test the stability of portable instruments.Results There was considerable difference in diurnal temperature and relative humidity between indoors and outdoors.In two field units,raw materials of foods were purchased in a centralized manner and suppliers were fixed,they were purchased independently in the othev five units. Facilities of food storage and transportation were lacking in all the seven units.In one of the fifty-three food samples, residues of pesticides exceeded the national standard.Among the three water samples,the level of turbidity,ammonia nitrogen and nitrate nitrogen was lower than the standard limits,but free residual chlorine and total chlorine were not detected.The plateau environment had no significant effect on spectrophotometers,but had significant influence on enzyme-linked immune detectors.Conclusion There are potential health hazards to training troops on the plateau that arise from foods and drinking water.Improvement of management and equipment adaptability is needed to further enhance the field health security efficacy.
