The World Health Organization (WHO) on Thursday said that several contaminated syrups and suspension medicines had been identified in the WHO regions of the Americas, Eastern Mediterranean, South-East Asia and Western Pacific.

The affected products are manufactured by Pharmix Laboratories in Pakistan, the WHO said, and were first identified in the Maldives.

The medicines, liquids containing active ingredients to treat various conditions, contained unacceptable levels of the contaminant ethylene glycol, WHO said.

The alert is the latest in a line of warnings from WHO about similarly contaminated medicines made in India and Indonesia, which were linked to the deaths of around 300 children worldwide last year.
