80 milk samples taken from 8 different milk plants were analyzed for nitrite and nitrate nitrogen and the concentrations were usually very low level. Milk tested had comparatively high nitrate-nitrogen contents of average 5.01 ppm with the range 4.01 to 7.10 ppm but lower than 10ppm, upper limit of freshmilk. However some of individual milk tested contained above 7.10ppm and may represent a hazard if used as the sole source for infant food.
