Can anybody specify me about the Metal size ( Fe, Non-Fe and SS) that can be tolerable by human body of all age groups including special risk group AS STATED BY WHO only ?
As we do have the critical limit of 2.0 mm for Non-Fe and SS and 1.5 mm for Fe in here but we are currently reviewing and Re-validating the critical metal limits.
I assume you are referring to a contamination in food.
You may need to define "tolerable". Regulatory factors take haccp precedence where existing.
Offhand i cannot recall ever seeing ANY official body making a general, triple, claim such as you mention. The converse is more likely to exist IMO.
From a Risk Assessment POV, are you referring to a single isolated occurrence or ?
