Certain products specifically for allergy sufferers have strange messages such as "non-quantifiable presence of an allergen". A PCR test can detect traces of a product's DNA, but it is impossible to quantify its volume because it is so small, or to trace the source of contamination.
They can't say there aren't any, there's no defined threshold or it's not possible to clearly quantify the quantity.
