In 2003, the UK Food Safety Agency tested six organic cornmeal products and 20 conventional (non-organic) cornmeal products for fumonisin contamination.
Food stalls dish out hearty country dishes like locro (a meaty stew from northwest Argentina), deep-fried empanadas, and humitas (lightly sweetened cornmeal wrapped in corn husks), all washed down with sweet patero wine - this is La Feria de Mataderos, an authentic celebration of Argentine country traditions.
