The death toll from the explosions at a fireworks market in central Mexico last week has risen to 36, health officials say.

A 39-year-old woman who sustained severe burns in the series of blasts at the San Pablito Fireworks Market died on Saturday.

Isabel Carpio Lozano died at the Lomas Verdes Trauma and Orthopedics Hospital, the Mexican Social Security Institute (IMSS) said in a statement on Sunday.

Carpio Lozano, who had burns over 90 per cent of her body, died "due to multiple cardiovascular, pulmonary, renal and hematological organ failure", the IMSS said.

The woman was transported to Lomas Verdes Hospital, located in the city of Naucalpan de Juarez, following the blasts at the fireworks market.

The explosions, one of the worst incidents of its kind in Mexican history in terms of fatalities, started on the afternoon of December 20 at the San Pablito Fireworks Market in Tultepec, a municipality in Mexico state located just outside the Federal District.

Mexico has experienced large losses of life in several accidents involving fireworks in recent years.

In March 2013, a fireworks explosion in the central state of Tlaxcala killed 16 people during a religious procession.
