| Summary: | This study was carried out to determine the current levels of nitrates in baby foods marketed in Lisbon, Portugal to estimate the toxicological risk associated with their intake. The nitrate content was determined in bottled baby foods of four varieties: vegetable-based foods, meat-based foods, fish-based foods, and fruit-based foods. A total of 39 samples were analyzed over the period 2010–2011. Average and median levels of nitrate in baby foods were lower than the maximum limits established by European Union legislation (200 mg kg−1). Median nitrate values in baby foods were 61, 30, 39, and 15 mg kg−1 w/w for vegetable-based baby foods, meat-based baby foods, fish-based baby foods, and fruit-based baby foods, respectively. The estimated nitrate daily intake through bottled baby foods for infants indicate that individually, these foods are not able to induce nitrate toxicity in the children population.
