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 so their presence in foodstuffs is strictly regulated.

Heavy, toxic metals 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. This proficiency test includes heavy metal detections to benchmark your testing capabilities within a multi-analyte testing environment.

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.
