This change required systems designed for complexity, speed, and scale in addition to custom and manual checks.<\/p>\n<p>Processed food is not the enemy. Uncontrolled processing is.<\/p>\n<p>Modern food safety has evolved when visibility replaces assumption, when verification replaces trust alone, and when responsibility extends across the entire food chain, not just at the point of production.
