An ammonia leak from a cold storage unit at a food company in China's commercial hub of Shanghai killed 15 people on Saturday and sickened dozens, the city government said.
The number of dead pigs found in a river which runs through Shanghai has reached nearly 15,000, officials and reports said Tuesday, as a newspaper claimed the government was concealing the true tally.
More than 1,000 dead pigs have been found floating in Shanghai's main waterway, the Chinese city's government said Monday, as residents expressed fears over possible drinking water contamination.
