Possible health hazards of pickled vegetables
In 1993, the World Health Organization listed traditional Asian pickled vegetables as possiblecarcinogens, and the British Journal of Cancer released an online 2009 meta-analysis of research on pickles as increasing the risks of esophageal cancer. The report, citing limited data in a statistical meta-analysis, indicates a potential twofold increased risk of esophageal cancer associated with Asian pickled vegetable consumption. Results from the research are described as having "high heterogeneity" and the study results indicated that further well-designed prospective studies were warranted. However, according to the authors, "The majority of subgroup analyses showed a statistically significant association between consuming pickled vegetables and Oesophageal Squamous Cell Carcinoma".
