They do. It is not wise to infer controversial information from ambiguous journalistic language. I typed "us organic certification cost" into google, and it helpfully quoted this at the top of the page [1] :
> Certification costs vary depending on the size of your production operation and on the accredited agency you choose to use. In general, organic certification costs run between $200 – $1500. Your costs will include an application fee, site inspection fee, and an annual certification fee.
I humbly suggest you might have taken a moment to check if your hunch was correct rather than leaving that to others.
Also its not possible for tests to confirm if produce is organic, but it possible to confirm it is not - if it contains traces of prohibited pesticides which are routine in non-organic produce then its not organic.[2]
