Fact check
“Manufacturers in Colorado can choose which samples labs test and which labs conduct the testing.”
Reasoning
The supplied sources consistently report that, despite proposals to overhaul the sampling system, the state has not yet eliminated the practice allowing manufacturers to choose which samples are sent for mandatory testing and which labs perform the analysis. This directly confirms the claim.
On confidence: Multiple recent ProPublica articles directly state that Colorado manufacturers still retain the ability to select both the product samples and the laboratories for testing.
Important context
The claim pertains to the current regulatory framework in Colorado. While there are ongoing discussions and proposals to change the system, the existing rules still permit manufacturers to make these choices.
