Interventions dominated the conference. Interventions are process steps that can be added in your plant and can eliminate or reduce to an acceptable level the identified hazard which in this case is, E. coli O157:H7.
As always there was spirited debate and in this case, science prevailed. By the end of the conference we all agreed that more testing will not make our products safe/safer. Testing has its place in the verification of plant sanitation and validating the effectiveness of interventions upstream.
