Frequently Asked Questions
What does "CFU/g" mean?
Colony Forming Units per gram: meaning how many living microorganisms are contained per gram of sample. The lower the number, the purer the sample.
What is "ppb"?
Parts per billion: one part in a billion. Concentrations of heavy metals are measured in this unit because very small quantities are detected.
How often are tests performed?
Our batches are regularly analyzed. You can find the current results on this page.
