Dumplings made by Wanchai Ferry contained golden staph.

Another popular Chinese brand's frozen dumplings have been found to harbor bugs linked to pneumonia, following a recent series of dumpling bacteria scares, the Beijing Morning Post reports.

Authorities in east China's Nanjing city have reported that dumplings made by Wanchai Ferry contained golden staph - bacteria that can cause pneumonia and blood poisoning.

The Nanjing Industrial and Commercial Administration has told local supermarkets to take the tainted dumplings off shelves and will conduct further investigations.

According to a Shanghai Daily report, the products in question, containing minced pork and a herb known as shepherd's purse, have also been banned from supermarkets in Shanghai and the local watchdogs have promised to carry out more frequent checks to ensure dumpling safety.

However, supermarkets in Beijing said they haven't yet received any notice of this recall.

Although golden staph bacteria can be killed if dumplings are heated to 80 degrees Celsius for 30 minutes, consumers said it is actually unfeasible as dumplings will become too soft and are ruined if cooked for more than 15 minutes.

By Thursday night, Wanchai Ferry still had not issued an official response.

This is the latest in a series of dumpling bacteria scares.

Last week, three types of Sanquan frozen dumplings and one made by Hai Pa Wang on sale in the southern Chinese city of Guangzhou were found to contain the same bacteria.

And last month, Beijing's business administrators said they discovered a batch of Synear dumplings containing golden staph during a July inspection.
