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.Food products containing CBD are now widely available in many countries, with approvals being granted for human consumption. The CBD component is purported to be health-giving, without the psychoactive THC component which is still a controlled substance. The CBD is most often added to novel food products in the form of a purified CBD oil. The purity and level of the CBD may be questioned, however, which is analytical testing has increased markedly in recent months. Approvals processes for CBD novel foods will require evidence of competence of the analytical testing, including contaminants such as heavy metals.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.Within this proficiency test the heavy metals Arsenic, Cadmium, Lead, Mercury are addressed. This challenges your laboratory to highlight any unsafe levels of these contaminants within Animal feed within one screening test. This is directly comparable to your routine analysis arrangement and as such results can be used to quickly inform any quality control decisions that may need to be made.
