Certain types of leafy vegetables such as spinach and lettuce may contain high levels of nitrate. In itself, nitrate is not harmful to the health of the consumers. However, nitrate can be converted into nitrite by the human body and high levels of nitrite can result in health issues for consumers. The EU has set specific maximum levels for a number of leafy vegetables, including spinach and lettuce. These levels are described in Regulation EC 1881/2006.
