At least 10 trailers filled food, water and medical supplies donated to victims of Hurricane Maria have been found sitting unattended in a parking lot outside a state elections office in San Juan, Puerto Rico.

The containers had been broken open and were infested with rats, The New York Times reported. A local radio station—Radio Isla—posted a video on Friday showing cases of a range of supplies, including food and water, covered in rat and lizard droppings.

The election commission office was being used a collection point for humanitarian supplies. Hurricane Maria devastated the U.S. territory when it swept over the island in September, leaving residents without power or running water for weeks. It was revealed this week that 1,427 people died a result of the hurricane, either when it hit the island or in the months that followed.
