The 2005 Indonesia food scare was a food scare in 2005 in Jakarta, Indonesia, when the government found that 60% of noodle shops in the capital had been serving noodles laced with formaldehyde, a known carcinogen. Noodles in the 2007 Vietnam food scare also had the same contaminant, and the chemical preservative had also definitely been found on tofu, noodles, and salted fish. Thailand has similar formaldehyde problems. Rumors spread that it was used on chicken as well. This was particularly bad in a nation like Indonesia where chicken is widely consumed because of the Islamic stance on pork.
