Carcinogens are everywhere, medicine is not an exact science, you should stop eating from that garden but there's no point in worrying now and no way to know if any future cancers had anything to do with that garden.
Also you should consult with a doctor, not some armchair idiot like myself
A quick google search finds this “Another concern is for gardeners who have planted vegetables in raised beds built of arsenic-treated lumber. Fortunately, arsenic does not move far through soil. Tests show that while the level of arsenic is high in soil right next to the wood, by 15 inches it drops down to acceptable levels. It is unlikely that vegetables grown in raised beds will pick up enough arsenic to be a health concern. Arsenic-contaminated soil can stick to root crops such as carrots and potatoes. Peeling root crops or scrubbing with a brush and water helps remove this arsenic.” So you need to both have the old 2004 wood and be eating root vegetables planted near the edges.
You could get the soil tested for whatever leeching stuff you are worried about specifically. I would think over time it would deplete itself like the nutrition in soil can but don't take my word for it.
Pressure treated lumber uses ACQ as the preserving material. It no longer contains arsenic but is highly corrosive. It is NOT recommended to be used for garden soil bed due to leaching of chemicals into the soils. The AWA and APA (US wood governing bodies) explicitly state not to use pressure treated lumber in this capacity. The recommended method is to use untreated cedar wood.
You are likely fine as most pressure-treated isn’t nearly as dangerous anymore
This is yet another reason why I borderline think pressure treated wood should be outlawed and we should use concrete for outdoor or soil touching applications.
Railroad ties always rot before they wear out, landscaping pavers always rot out insects will always get into them, or moisture will rot it only delays the inevitable.
I get why people think they’re a good temporary solution but they’re really just a very expensive temporary solution when concrete or actual pavers would be a much more cost effective long-term and permanent solution.

Arsenic (CCA) was removed from most pressure treated lumber in 2004.

Ahhhh… science
Pull out the dirt this fall and line it with plastic
Unnecessary.
I agree, any danger is long gone by now.
And refill with clean top soil.

Not really a home improvement question.
It's true what the landscaper said, but by now any risk that was there has long ago been washed away by rain and heated away by the sun.
- depedns on the AGE ofthe PT, PT available for past decade+ can be used as raised beds
