Dietary supplement manufacturers often treat contaminant testing as a compliance formality, with price and turnaround being the only differentiating attributes between laboratories. The reality is these products pose a number of analytical challenges, and laboratories make a series of decisions that determine the comparability, reproducibility and defensibility of the data they generate.

Two accredited laboratories can test the same product and produce results that are directionally aligned yet materially different. At higher concentrations, these differences may be inconsequential. At trace levels particularly for heavy metals, pesticides and microbiological contaminants they can determine whether a product is compliant or not with regulatory standards or retailer requirements.

As quality standards rise and data accessibility grows, the risks posed by analytical variability become more visible and problematic. Manufacturers can no longer treat testing as a box to check and need to properly vet the laboratories they use to make sure the data they generate can withstand cross-laboratory comparison and public scrutiny.

Anresco Laboratories was proud to attend the ACIL - American Council of Independent Laboratories P2 Meeting in Washington, D.C., where key leaders across the laboratory industry came together to discuss critical policies, regulatory developments, and the future of independent testing.

Being part of this event is incredibly important to Anresco. It allows us to stay actively involved in the conversations shaping industry standards, compliance, and best practices at both the national and regulatory level. Our presence ensures that we are not only meeting today’s requirements but helping influence the future of quality and safety in laboratory testing.

Anresco is committed to promoting the highest standards for quality and safety across the industries we serve (food, imports, cannabis, h**p, dietary supplements, and more), and there is no better event than ACIL P2 for this purpose.

Thank you for following our journey as we continue to represent our clients and the laboratory testing community at the highest level.

In cannabis-infused beverages, what’s inside the can matters but so does what lines it. Use an improper can liner and rates of ‘scalping’ (i.e. cannabinoid adhesion to the can liner) can increase dramatically, reducing the potency and viable shelf life of beverage products.

Harold Han of Vertosa and Vu Lam of Anresco Laboratories collaborated on this article to explain how we tackled a growing industry challenge:
👉 How do you verify your can liner type with confidence?

Using advanced FTIR analysis, this work introduces a reliable way to identify liner materials and support product stability from production to shelf.

Minnesota is taking steps to ease pressure on h**p THC manufacturers.

A new bill awaiting the governor’s signature would allow h**p beverage and edible manufacturers to continue out-of-state testing until May of 2027. This is important because in-state labs currently lack the capacity to handle the analytical demands of the h**p industry, in addition to that of the Minnesota adult-use cannabis industry. In-state labs also lack the experience and capability to offer panels simultaneously satisfying the analytical requirements of other states regulating intoxicating h**p products (e.g. Georgia, Texas, Florida).

The relief provided will save Minnesota h**p manufacturers will significantly reduce the time needed to get products to market and prevent the need to test batches in duplicate (once for in-state compliance and once for out-of-state compliance).
