Melamine And Food Safety - 1

The misuse of melamine, namely the adulteration of various food products with the chemical, raised significant public health and food safety concerns in the first decade of the 21st century. Beginning in the late 1950s, melamine was utilized as a nonprotein nitrogen (NPN) compound in ruminant feed, since microorganisms in the ruminant stomach are able to metabolize the chemical into protein. However, the addition of melamine to animal feeds was later discouraged, since the process of microbial protein generation from melamine was inefficient and resulted in the release of potentially toxic amounts of ammonia by product. Although many manufacturers switched to the use of more-efficiently metabolized NPNs such as urea, melamine use in animal feeds persisted, particularly in China, where manufacturers illegally added large amounts of melamine to a variety of products to pass industry tests, specifically the Dumas test and the Kjeldahl method. These tests are frequently used to detect protein levels in milk and other food products based on nitrogen content. Because melamine is abundant in nitrogen, these tests are unable to distinguish between melamine-contaminated and melamine-free products.
