Is your Swiftlet’s Nest Free from Nitrite?

The issue of Swiftlet’s Nests containing harmful substances such as nitrite has raised concerns amongst many people, especially pregnant mothers who eat them regularly during their pregnancy stage. In 2011, surveillance conducted by China authorities found that high levels of nitrite was present in various Swiftlet’s Nest, in particular, the blood-red Swiftlet’s Nest. Nitrite occurs in the environment, in food and water, and is produced inside living organisms. It can be used as food additive, mainly as a preservative and colour fixative in foods such as cheese products as well as cured and fermented meats.

According to the World Health Organization, the permissible level of nitrite in food is 34ppm. Some scientific studies have shown that nitrite naturally forms in Swiftlet’s Nests due to a natural fermentation process which occurs in the environment all the time. Some studies also suggested that the high levels of nitrite in Swiftlet’s Nest may be due to environmental contamination e.g. from bird droppings which contain high levels of nitrite.

“According to the World Health Organization, the permissible level of nitrite in food is 34ppm.”

Nevertheless, it should be noted that nitrite can only be harmful if consumption exceeds standard levels for our bodies. Excessive amounts can decrease the ability of red blood cells to transfer oxygen throughout our body. Moreover, it can react with our stomach juices to form nitrosamines which are potentially carcinogenic. It is known that babies who consume nitrite-contaminated water will result in developing a serious health condition called methemoglobinemia, which is also known as ‘blue baby syndrome’.
With these rising concerns, consumers are naturally more discerning when it comes to selecting Swiftlet’s Nests. As mentioned, nitrite is inherently present in Swiftlet’s Nest due to natural biological processes. However, it is possible to achieve negligible levels of nitrite in Swiftlet’s Nest through proper Swiftlet’s Nest farming techniques and comprehensive cleaning during the processing of the Swiftlet’s Nest.
