At its core, CRISPR works like a genetic search-and-replace tool. The system uses guide RNA to locate specific DNA sequences and the Cas9 enzyme as molecular scissors to make precise cuts. … This precision surpasses conventional approaches; where antibiotics kill bacteria indiscriminately and chemical washes may leave residues, CRISPR offers a surgical strike against pathogens.

…

CRISPR isn’t just for editing genes – it’s revolutionizing how we detect contamination. New CRISPR-based diagnostic tool … can identify pathogens in under an hour, compared to days for traditional lab tests. Companies like Mammoth Biosciences are developing portable CRISPR detectors that could be used in fields, processing plants, or even grocery stores to screen food in real time.

Looking ahead, CRISPR’s impact on food safety could extend far beyond pathogen elimination:

…

Allergen-Free Foods: Researchers are using CRISPR to remove allergenic proteins from peanuts, wheat, and other common allergens, potentially preventing many food-related illnesses.

Climate-Resilient Food Systems: As climate change increases food safety risks (warmer temperatures accelerate pathogen growth), CRISPR-enhanced crops and livestock could provide crucial resilience.
