Abstract: Forty random imported samples of natural pasteurized cow's butter (20 each of salted and unsalted samples) were collected from different supermarkets at Damietta City for analysis colorimetrically by using spectrophotometer to determine the level of nitrate and nitrite. The obtained results revealed that the mean values of nitrate in salted and unsalted samples were found to be 0.795+0.124 and 0.352+0.062 mg/kg respectively, while the average values of nitrite in salted and unsalted samples were 0.011+0.0002 and 0.012+0.0002 mg/kg respectively. Presence of nitrate and nitrite levels in butter may be ascribed to various sources rather than preservatives. Although butter must be free from these components, the obtained concentrations may favor carcinogenic nitrosamines formation which constitutes a hazard for human health. The public health hazards have been discussed.
