“…These results coincide with those found by Tam et al (2006), who reported higher coincidence and levels in corn-based breakfast than in wheat-based samples. However, OTA and ZEA were mainly found in wheat-based and wheat and rice-based samples, with the maximum levels found in wheat-based products.…”

, respectively. The cooccurrence of OTA and ZEA was observed in 28% of the samples. Aflatoxin B1 appeared only in the corn-based breakfast cereals, whereas ZEA and OTA showed the highest contamination rates in the samples containing wheat and wheat and rice, respectively. No sample of high-fiber content was contaminated with AFB1, whereas OTA and ZEA occurred with higher incidence in high-fiber content samples. Moreover, the daily exposure to AFB1, OTA and ZEA is discussed.

Infants have a more restricted diet and they generally consume more food on a body weight basis than adults. Therefore, the significance and potential health risk of any contaminant in foods consumed by infants is increased and diligent attention must be paid to this particular area. The present study aims to determine the occurrence of aflatoxin M 1 (AFM 1 ), aflatoxin B 1 (AFB 1 ) and ochratoxin A (OTA) in processed cereal-based foods (flours) and infant formulae (milk powder) available in the Portuguese market, both sold as conventional and organic origin. Mycotoxin determination was carried out using a method previously applied to duplicate diet samples. This method employed chloroform extraction, liquid-liquid extraction, immunoaffinity column (IAC) cleanup and HPLC analysis with fluorescence detection after postcolumn derivatisation. Quantification limits were 0.014, 0.004 and 0.028 μg kg −1 for AFM 1 , AFB 1 and OTA, respectively. These toxins could only be quantified in 12 of 27 analysed samples (15 positive results): two samples with AFM 1 , two samples with AFM 1 and OTA, one sample with AFB 1 and OTA and seven samples with OTA. Positive results concerned four for AFM 1 (26%), one for AFB 1 (7%) and ten for OTA (67%). For these samples, contents ranged between 0.017-0.041 μg AFM 1 kg −1 , 0.034-0.212 μg OTA kg −1 , and one sample had a value of 0.009 μg AFB 1 kg −1 . Considering the presented results, we could provisionally conclude that the presence of these mycotoxins in baby foods does not constitute a public health problem. These are the first results concerning the occurrence of mycotoxins in marketed baby foods in Portugal and this is the first study using the HPLC method, proposed for duplicate diets, in baby food sample analysis.

“…A study of mycotoxins in infant foods ncluding cereal-based infant foods-soy, wheat, oat, i Values are mean (n = 3) ± standard deviation; ND = not detected (<1.0 log 10 CFUg -1 ). Tam et al [32] analysed 349 breakfast and mixedgrain infant cereals samples and should that 50% of both breakfast and infant cereals contained (limit of detection = 0.002 ng·g -1 ) AFB 1 . Only 4% of the breakfast cereals and 1% of the infant cereals had AFB 1 concentrations exceeding 0.1 ng·g -1 , which is the European Union maximum limit for aflatoxin B 1 in baby foods and processed cereal-based foods for infants and young children.…”
