In the body: no agency opinion we hold names an effect at the amounts found in food, so it is shown for context, not rated.

Not rated by dose: a flag on one reviewed food, Brazil nuts, raw.

Background. Shown, not scored: no dose basis at normal intake, a classification rather than a risk, or legal limits only.

    How it’s rated

    Context only: no Barium reference was opened (the paper cites a US EPA RfD of 0.2 mg/kg body weight/day = 14 mg a day at 70 kg; not read in the agency's own document, so recorded as missing here). 30 g contains 51.6 mg total barium, but only about 2% was bioaccessible in vitro (about 1 mg).

    Intake: 30 g shelled serving · Level in the food: 1,720 µg/g (mean ± standard deviation 1,720 ± 90, whole nuts (literature 49-2,476), n = 1)

    Measured on: Barkleit 2025: one commercial batch of whole Brazil nuts; Germany
