An annual Interpol campaign to stop illegal medicine shipments resulted in the seizure  315 packages of illegal pharmaceuticals which were destined for the Netherlands, Dutch health ministry inspectors said on Monday.

The five day operation, named Pangea X, also resulted in the closure of 10 websites in the Netherlands which were involved in the illegal drugs trade and three cases have been referred to the public prosecution department.

In total, 10,000 packages destined for Dutch buyers were checked on their contents. The 317 packets which were confiscated contained almost 50,000 doses, the inspectors said.

Although just 315 packages were seized in the Netherlands, this is up 61 on last year’s crack-down, broadcaster NOS said. Most contained erection aids, slimming pills and tranquilisers.

Worldwide, 715,000 packages were checked during the campaign, which was held for the 10th time this September.
