Jakarta, Apr. 17 : Muslims in Indonesia have been left outraged, following the discovery that Indonesia's popular dry-meat-product-selling companies were substituting beef with pork.

After conducting DNA tests on jerky samples from traditional markets in Java and Sumatra, Indonesia''s National Food and Drug Monitoring Agency BPOM found that five companies were deceiving Muslim sentiments by contaminating their products with pork.

"I can imagine how furious the public, particularly Muslims, would be once they find out that they have been deceived all this time,'''' News. com. au quoted BPOM head Husniah Rubiana Thamrin, as saying.

The agency also found that though some of the pork products were labelled halal, they were not.

Halal meat is considered to be suitable for Muslims.

The agency believes producers used pork to increase their profits, because it is cheaper than beef.

About 90 per cent of Indonesia''s 240 million people are Muslim. (ANI)
