"Had the specialists said that, 'Yes, we judge that determination is thing successful communal wrong those patients,' past that would person triggered much work, much probe to find the communal causes and the biology aspects would person been portion of that."

The latest probe started with a "scoping exercise" successful May 2023 aft Marrero provided "actual trial results suggesting elevated levels connected immoderate biology substances, much specifically dense metals and pesticides," including glyphosate, Léger said.

Some patients and advocates person questioned wherefore Public Health couldn't person started this probe sooner, based connected the diligent forms Marrero had antecedently submitted, but Léger said they "needed to marque definite that the information is arsenic implicit and close arsenic possible … truthful that the findings from the investigation tin beryllium relied upon."
