The CONTAM Panel concluded that the typical daily human dietary exposure to nitrite from fresh animal products (e.g. milk, meat and eggs) is only (2.9 %) of the total daily dietary exposure to nitrite. The CONTAM Panel concludes that such low nitrite levels in fresh animal products do not raise any concern for human health.
