Plans to feed poor children reconstituted food made from leftovers near expiry have sparked a row in the Brazilian city of São Paulo.

The product, known as farinata from the Portuguese word for flour but dubbed “dog food” by critics, can be eaten as pellets or added to meals.

Mayor Joao Doria says it could curb hunger and cut food waste.

But critics have questioned its nutritional value and prosecutors have opened an inquiry into the plans.
