How can I prevent cross-contamination when preparing several fermented foods?
Clean and dry equipment appropriately, keep raw and ready-to-eat foods separate, and avoid sharing utensils between batches without washing. Follow food-specific sanitation guidance rather than assuming visible cleanliness is enough.
Why it happens
Cross-contamination occurs when microbes or residues transfer between ingredients, hands, utensils, containers or surfaces. Fermentation containers may carry organisms from a previous batch.
How it works
Microbes transfer through contact, moisture and residues. Cleaning reduces contamination, while separate equipment or thorough washing interrupts transfer pathways.
