If an astronaut throws up in zero gravity, one thing’s for sure: it’s not because they have food poisoning. And how do we know? Because in the late 1960s, NASA pioneered a radical new approach to food safety that became the global gold standard—one that even smaller CPG brands working out of commercial kitchens rely on today.

Pillsbury’s Moonshot

Food safety has always been a public health concern, but space travel raised the stakes. A sudden illness could jeopardize an entire mission. So, NASA turned to Pillsbury, one of the world’s top food manufacturers, for help.

At the time, food safety relied on end-stage pathogen testing—costly and unreliable. Pillsbury found a better way: inspired by NASA’s quality control in rocket building, they designed a system to identify “Critical Control Points” (places where contamination might occur) and set measurable “critical limits” (like cooking temps and pH levels). If anything drifted outside safe limits, corrective actions kicked in immediately. This process, dubbed Hazard Analysis and Critical Control Points (HACCP), ensured a clear paper trail, making it easy for auditors to verify food safety every step of the way.

Going Viral

HACCP took off at the 1971 National Conference on Food Protection. The FDA soon tapped Pillsbury to train canned food inspectors, and by the 1980s, global agencies like the World Health Organization and the European Union mandated it. The USDA adopted it for meat and poultry in 1996, and in 2011, the Food Safety Modernization Act (FSMA) cemented HACCP as the standard across the U.S. food industry. A system built to prevent foodborne illness had officially gone viral.

Why It Still Matters

More than 50 years later, HACCP remains the backbone of food safety, for small-batch CPG brands, national brands, and everyone making food for the public. Whether you’re scaling your first product or running a full-scale operation, preventing quality issues in-process is far more effective than catching them later—saving time, money, and your brand’s reputation.
