A total of 125 random meat products samples (25of each of locally processed beef luncheon, locally processed chicken luncheon, imported canned beef luncheon, imported canned chicken luncheon, imported corned beef) collected from different supermarkets distributed in Mansoura City, Egypt were analyzed for determination of nitrite content (ppm) using spectrophotometer. The nitrite was detected in all (100%) examined samples with higher levels occurred in imported canned chicken luncheon followed imported corned beef. The mean±SE values of the different metal detected in locally processed beef luncheon, locally processed chicken luncheon, imported canned beef luncheon, imported canned chicken luncheon and imported corned beef 23.80±2.44 ppm, 37.82±4.24 ppm, 19.74±1.05 ppm, 56.94±5.47 ppm and 61.93±8.09 ppm, respectively. Interestingly, the levels of nitrite detected in all tested samples were within the maximum permissible limits except 8 % of canned chicken luncheon and 32% of imported corned beef samples had nitrite by levels exceeded the maximum permissible limits set by the Egyptian government. The estimated daily intakes (EDI) of detected nitrite were lower than their acceptable daily intake (ADI) stated for it in all tested samples except for imported canned chicken luncheon and imported corned beef, their EDI exceeded the ADI. Target hazard quotient together with hazard index values of nitrite were below 1.0 in all examined samples. Health risk assessment based on EDI suggesting that there were significant health risks on public from the consumption of some meat products like imported canned chicken luncheon and imported corned beef marketed in Mansoura City, Egypt.
