🚨 Did you know imported products may be put under ‘automatic detention’ if they’re deemed by the FDA to be high risk? It is then the responsibility of the importer to prove that the product is safe rather than for the FDA to prove its unsafe.

Anresco Laboratories has provided import detention sampling & testing services since 1981 and are true experts at navigating the FDA DWPE (Detention Without Physical Examination) Program. Reach out if we can be of assistance.

We felt it important to share our full comment regarding the DCC’s proposed changes to their pesticide testing requirements, as the portion that didn’t make it into the article provides nuance and context regarding our position.

At a high level, setting uniform action limits and incorporating additional pesticides of concern are good changes for the DCC to make. We just think there may be some unintended consequences resulting from the formulation used to determine action limits for different product matrices. We understand it’s an iterative process and look forward to working with the DCC on the matter.

is proud to have successfully transitioned our Provisional License to an Annual License issued by the Department of Cannabis Control Licensing Division. This required a full review of our Method Validations and Standard Operating Procedures by qualified scientists within the DCC Laboratory Services Division. This was no small feat as it involved the submission of data packages, CEQA compliance, and around 12 technical methods and 17 SOPs including extraction and analysis for cannabinoid content, all required contaminants, as well as sampling and transport, sample processing, and sample retention and disposal. While it was a long and arduous process, we feel it is absolutely necessary to ensure a compliant and level playing field for labs performing compliance testing going forward. All testing laboratories were made aware a few years ago that they would be required to transition to an annual license this year before their provisional expires, and that they needed to be actively working toward annual licensing in order to ensure they are able to transition in a timely manner as the DCC is not granting extensions to provisional licensing. A special thank you to our QA and technical staff for their hard work and ongoing commitment to quality and compliance!
