More than 30 cases of food poisoning have been spotted among migrants taking refuge on the Greek island of Leros, according to activists.

The Action Group for Palestinains of Syria (AGPS) quoted activists as stating that dozens of migrants, mostly children, were taken by ambulances to a local hospital for treatment.

The activists attributed the health crisis to rotten meals “unfit for human consumption” which were handed over to the migrants.

Dozens of Palestinian refugees are taking refuge in substandard facilities set up in Leros Island, where they have been subjected to an exacerbated humanitarian situation due to the absence of vital services, including health care, housing, relief assistance, and clean water.

In recent years, Greek refugee camps have reportedly been running at three times their capacity. Overpopulated refugee camps cause a shortage of resources, not least healthcare.
