Sodium nitrite appears predominantly in red meat products (you won’t find it in chicken or fish products).
If sodium nitrite is so dangerous to humans, why do the FDA and USDA continue to allow this cancer-causing chemical to be used? The answer, of course, is that food industry interests now dominate the actions by U.S. government regulators. The USDA, for example, tried to ban sodium nitrite in the late 1970′s but was overridden by the meat industry.5 It insisted the chemical was safe and accused the USDA of trying to “ban bacon.”
Today, the corporations that dominate American food and agricultural interests hold tremendous influence over the FDA and USDA. Consumers are offered no real protection from dangerous chemicals intentionally added to foods, medicines and personal care products.
