Test Description

This test material is rice, which is provided as rice flour.  Rice flour has a number of uses within foodstuffs, both as a substitute for wheat flour, but also as a standalone ingredient in a range of processed foods. It is used within many foods suitable for freezing and as a thickening agent due to its liquid separation inhibiting characteristics.

The presence of metals in food is of particular concern due to their toxicity. These naturally occurring chemicals can occur as residues in food by a range of mechanisms such as their natural presence in the environment or contamination during food processing and storage. Their accumulation in the body can lead to harmful effects over time and their presence in foodstuffs is strictly regulated.

This strict regulation requires effective and accurate testing capabilities, which through proficiency testing can be maintained or achieved.

Heavy, toxic metals such as arsenic, cadmium, lead and mercury are often found in food, either as a natural contaminant or a contaminant from production. Their effects are various and far reaching, such as inhibiting nutrient absorption in the case of cadmium.

Heavy metals are found more commonly within intensively farmed produce, and with the increasing demand for foodstuffs around the globe, larger, more intensive farming will occur and bring an increased risk of contaminants such as heavy metals. This all links to a need for accurate testing practices, which can be achieved through effective proficiency testing.
