Is sodium nitrate bad for you?

The health concern is nitrosamine formation when nitrites react with proteins at high heat; IARC classifies processed meat as Group 1 partly on this basis. The EU cut maximum permitted nitrite/nitrate levels under Regulation (EU) 2023/2108 (applying from October 2025). Within the strict limits, regulators consider the botulism-protection benefit to outweigh the risk.
