Heavy, toxic metals such as cadmium, lead and mercury are often found in food, either as a natural contaminant or a contaminant from production. Heavy metals accumulate in the food chain from the environment, a particular issue for marine food sources. It is therefore important to show strong, accurate testing capabilities throughout a range of specific analytes in matrices such as mussels. Heavy metals can be found within manufacturing processes as well as in contaminated seas. This can increase the risk of heavy metals within foodstuffs to consumers.Fapas proficiency tests aim to minimise this risk, and, by benchmarking your testing ability, can provide you with the insights you need to make key improvements in your testing processes. This all helps you provide your clients with the confidence they need in your testing ability, allowing them to make the informed decisions needed within their business to achieve success.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.
