CHINA — Two Chinese pharmaceutical companies have recalled their rabies vaccine and heart medication respectively after they were found to be tainted.

Changchun Changsheng Biotechnology was found to be illegally producing "freeze-dried human rabies vaccines," reports Xinhua.

The company reportedly fabricated production records and product inspection records.

Zhejiang Huahai Pharmaceutical voluntarily suspended production of a heart drug after it was found to contain N-nitrosodimethylamine, or NDMA, reports Precision Vaccinations.

The European Medicines Agency found the chemical "tainted with an impurity linked to cancer," reports Reuters.

NDMA was found in an ingredient called valsartan, which the company used to create drugs aimed at treating high blood pressure and heart failure.

Chinese citizens have voiced their opinions about the situation on Chinese social media, with one netizen saying "if the state does not protect its citizens, how can we love our country?"

According to Xinhua, authorities have launched an investigation and plan to conduct more unannounced inspections in the future.
