It's on you to go sniff the butt of the journal that publishes a research article and see if they're legit. You're also on the hook for seeing if there have been any retractions, letters of concern, articles in reply, and who if anyone cited the thing you're reading.
Some journals offer tools specific to themselves to help you with some of this, and there are a few non-journal services that can help you get some of this information across journals (google scholar, pubmed, etc...) but they're scattershot and discipline specific.
