The occurrence of Polycyclic Aromatic Hydrocarbons (PAHs) in foodstuffs is a major source of exposure to these carcinogenic compounds for humans.  Given the risk to human health from PAHs in food, the European Commission established maximum levels for PAHs and identified a group of 4 PAHs as indicators based on occurrence and toxicity in EC 1881/2006. 

PAHs continue to be a risk to food safety across a range of foodstuffs, due to the widespread cooking methods associated with PAH addition. As a result effective testing capabilities aer needed to highlight any potentially high levels of PAHs within processed foodstuffs, such as palm oil. This is in an effort to promote high quality foodstuffs present within the global supply chain as well as protecting the end consumer from any potential contamination.

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 pesticide residues.

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.
