Nicaragua ? Nicaraguan police have seized more than 40,000 tubes of Chinese-made toothpaste suspected of containing a chemical that killed at least 51 people last year in Panama.

All U.S. imports of Chinese toothpaste were halted last week to test for diethylene glycol – a chemical commonly used in antifreeze and brake fluid.

Nicaraguan Health Minister Maritza Cuan said Thursday at a news conference that officials fear as many as 80,000 tubes may still be on the local market.
