A HOCl concentration-dependent 3-chlorotyrosine formation was observed in treated iceberg lettuce. For iceberg lettuce, the analytical method allowed to detect the use of as low as 1.41 mg HOCl/L. 3-Chlorotyrosine was detected above LOD in 97, 24 and 14% of the lettuce mixes, vegetable mixes and frozen vegetables. Exposure to 3-chlorotyrosine from the frozen vegetables and vegetable mixes was lower compared to the lettuce mixes. Chlorotyrosine exposure via lettuce mixes could be considered as a public health concern.
