Cross-contamination happens when harmful pathogens transfer from one food, surface or person to another. The risk of foodborne illness is particularly high if raw meat, poultry, seafood or eggs are involved.
Raw meat, poultry, seafood and eggs can carry pathogens like Salmonella, Campylobacter and E. coli, which can be eliminated through correct cooking procedures. Ready-to-eat food won't get that same heat treatment, so if pathogens transfer onto it at any point, there are no steps left in the process to remove the risk.
This is what makes cross-contamination especially dangerous compared to other food safety failures. The food can look, smell and taste completely normal while still carrying enough bacteria to make someone seriously ill. It's also one of the easier risks to control once staff know where it hides, since most cross-contamination comes down to a handful of repeatable habits rather than anything complicated.
Tip: A dedicated bottom shelf for raw protein storage removes the guesswork for every person who opens that refrigerator.
Show your team's separation setup: dedicated raw-prep stations, color-coded boards or a labeled refrigerator shelf order. Share it on social media tagged #NFSEM2026, or use this week to walk staff through where cross-contamination risks actually hide in your kitchen.

Cross-contamination is the transfer of harmful pathogens from one food, surface or person to another, most often from raw meat, poultry, seafood or eggs to ready-to-eat food.
On the bottom shelf, in a sealed container or on a tray, so juices can't drip onto food stored below it.
Only if you boil it first. Pouring it over finished food without cooking it thoroughly carries the same risk as the raw meat it touched.
NFSEM is a US campaign held every September, running since 1994, to raise awareness of safe food handling. Userve marks it with four weekly themes: Clean, Separate, Cook and Chill.
