Mexico State health officials said about 60 people were hospitalized for injuries from Tuesday's explosion, some with burns over 90 percent of their bodies.
Mexico State authorities told The Associated Press Wednesday that the death toll was expected to go up because 11 people were listed as missing and because body parts were found at the scene.
The explosion was so deadly, in part, because it's currently the busy season for the market, which was well-stocked and full of buyers looking for pyrotechnics for the holidays.
"We are obviously in the high season," Tultepec Mayor Armando Portuguez Fuentes said. "There was more product than usual because we are a few days away from Christmas, a few days away from New Year's, and those are the days when the products made here are consumed the most."
Authorities have not indicated what may have caused the explosions.
