Food safety incidents don't stay local anymore. A contaminated batch produced in one facility can reach consumers on multiple continents before anyone realises something is wrong. That shift in scale is exactly why the 3-A sanitary standards, a framework that has been evolving for almost a century, continue to matter for everyone who designs, buys, or operates food production equipment. In this episode of Behind Clean Lines, host Mikkel Svold is joined by two guests with very different relationships to hygienic design. Gabe Miller is a 3-A Certified Conformative Evaluator (CCE) who served as chair of the committee that developed the 3-A General Standards. He has spent his career inspecting food production equipment for compliance, and he continues to collaborate with EHEDG as a trainer at their conferences. Tue Skrubbeltrang is Sales Director for EMEA and APAC at NGI A/S, where he works with around 5,000 OEM customers worldwide. Between them, they cover the regulatory, engineering, and commercial sides of a conversation that too rarely happens in the same room.The occasion is the third major iteration of the 3-A General Standards, recently released. Rather than imposing sweeping new requirements, it clarified language that had been causing genuine disputes in the field, expanded the tables of accepted materials to reflect modern production realities, and updated the framework to accommodate newer manufacturing technologies such as 3D printing and injection-moulded metals. Listen in for an unusually candid look at what the standards actually demand, where the industry keeps getting it wrong, and why the biggest risk in food safety today may not be what you think it is.

Breaking the myth 11:06 – What the latest update actually changed 16:43 – New manufacturing technologies and what the standards now allow 17:58 – Defining product contact surfaces: where most people get it wrong 21:49 – Edge cases: conveyor belts, bearings, and the one-inch rule 25:51 – Non-product contact surfaces and the door frame listeria case 30:58 – Cleanability as commercial advantage: downtime, cost, and the 30-year argument 33:43 – 3A and EHEDG: convergence, differences, and cross-border certification 37:54 – Wishlist: knowledge first, not stricter standards In This Episode What the latest update to the 3-A General Standards actually changed, and what was deliberately left the sameWhy the definition of "product contact surface" reaches well beyond the surfaces your product visibly touchesHow a year-long listeria problem in a meat processing plant was traced back to the hollow bottom of a door frameWhy bearings demand careful hygienic consideration even when they sit outside the product contact zoneHow the 3-A and EHEDG standards are converging, and where genuine differences in approach remainResources Mentioned 3-A Sanitary Standards (the long-standing framework governing hygienic design of food production equipment in the US)EHEDG, European Hygienic Engineering and Design Group (the European hygienic design framework, with growing harmonisation agreements with 3-A)Contact and Follow Questions, topic ideas, or guest suggestions: podcast@ngi-global.com Find more episodes here.
