Maximum residue limit (MRL) explainer

As part of the registration process, the registering chemical company must provide data that shows the maximum residue limit (MRL), i.e the maximum amount of residue that can be expected in the grain at harvest when the correct use pattern is followed. If the MRL data shows that the expected residue amount would pose a health risk for consumers, then the product will not be registered for the proposed use pattern.

The 'health risk' is assessed based on the way the grain product is likely to be consumed. So, in Australia the amount of and the way chickpeas (for example) are consumed is different to how they are consumed in India (for example). Therefore, the Australian MRL may differ from the Indian MRL. Also, pulses are commonly eaten with very little processing or mixing with other foods. In many overseas countries the pulse grain is simply split and then boiled and eaten, often with few other ingredients, to form a meal.
