Heavy, toxic metals such as arsenic, cadmium and lead are often found in food, either as a natural contaminant or a contaminant from production. Many heavy metals, such as Arsenic, can be absorbed within production from poor quality, or contaminated land. This uptake of heavy metals is of particularly high risk within wine due to the large amount of time taken for the grapes to grow and ripen. Combine this with the use of some heavy metal based plant protection products, gives great importance in accurate testing to isolate and detect these potential contaminants within foodstuffs.
Due to the higher price of wine and by extension other alcoholic beverages the need to ensure high quality testing over a long term timescale is extremely important to mitigate any risks of contamination.
Heavy metals and other trace elements within foodstuffs must be quantified and controlled to ensure that high quality produce is passed to the consumer. It is only through effective testing practices that manufacturers products can be sold as intended.
To ensure the high quality testing, effective quality assurance measures are required. Fapas reference materials can allow you to validate prospective methods due to the known uncertainty ranges associated. Fapas reference materials can also be used to accurately calibrate instrumentation used within your testing arrangement, this can safeguard your testing capabilities against any unconscious bias.
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 can challenge labs to prove their accurate testing credentials, and Fapas testing arrangements provide the best way to show this, offering a way to track your laboratory's testing ability across a long timescale, evaluating and refining your quality control processes to provide highly accurate testing across a multitude of analytes within one test substance, as well as across many analyte/matrix combinations.
