And as I say, in spite of the fact that eight different possible locations were looked at in terms of production, processing, and possible contamination points, in no situation could we definitely link a common cause through the whole system that would say this is where the contamination took place four months ago.
Nous avons inspecté huit établissements différents, c'est-à-dire leurs procédés de production, de traitement, les causes possibles de contamination, et nous n'avons jamais été en mesure d'établir un lien, de déterminer que la source de la contamination provenait de tel endroit.
