Abstract
This study estimated exposure to multiple mycotoxins in 249 infants aged between 6 and 12 months in three agroecological zones of Tanzania. Maize-based complementary food intakes were estimated using two 24 h dietary recalls. Using @ Risk software, probabilistic exposure assessment was conducted by modeling maize intake data (kg/kg body weight/day) with previously determined multiple mycotoxin (except for ochratoxin A (OTA) and zearalenone (ZEA), present in only a few samples) contamination data (mu g/kg) in maize. Maize intakes ranged from 0.13 to 185 g/child/day (average = 59 +/- 36 g/child/ day). The estimated mean exposures were higher for aflatoxins (6-fold), fumonisins (3-fold), and deoxynivalenol (2-fold) than health-based guidance values of 0.017 ng/kg body weight/day, 2 mu g/kg body weight/day, and 1 mu g/kg body weight/day, respectively. The population at risk of exposures above the limits of health concern ranged from 12% for HT-2 toxin through 35% for deoxynivalenol to 100% for aflatoxins. The exposure varied among the agro-ecological zones. Strategies targeting multiple mycotoxins in maize are urgently needed to minimize exposures in Tanzania.
