Health Minister Perrin Beatty responds to concerns of person made sick by pesticides

In the case of pesticides affecting health, there is not necessarily the repeated, controlled circumstances of a person reporting sensitivities. The same arguments that apply to persons with sensitivities do not apply when arguing about the onset of sensitivities. i.e. human rights and clinical ethics require us not to subject persons who experience repeatable controllable circumstances to a reverse onus, but identifying a one-off exposure as the cause of developing sensitivities is more complicated.
