Sous-vide Chicken Pasteurization Time

Sous-vide pasteurization of chicken

Sous-vide pasteurization clears Salmonella spp. from poultry by keeping the meat at a precise temperature long enough to reach at least a 6.5 log10 reduction (D-value). Heat kills as a function of both how hot and how long, which is why a cooler bath just means you wait longer. The classic Baldwin tables (Douglas Baldwin, Sous Vide for the Home Cook) list pairs like 60 C / 35 min, 65 C / 9 min and 70 C / 90 s, all read at the geometric center of the cut.

Total time = come-up time (heat working its way through the thickness) + the pasteurization hold. Come-up roughly follows thickness squared, so a 4 cm breast can run twice as long as a 2 cm one even when the target temperature is identical. Measure thickness rather than weight, and check the bath with a calibrated thermometer.

Applications

Restaurant kitchens and home cooks lean on sous-vide for juicy, safe chicken breast at 60-62 C, which sounds risky next to conventional roasting but is fully pasteurized once the hold is right. The same approach covers confit thighs, chicken galantines, and meal-prep batches meant to be chilled and reheated. In Brazil the work falls under ANVISA RDC 216/2004 (good food-service practices) and the RDC 12/2001 microbiological limits.

FAQ

Is 55 C safe for chicken? No. Once you drop below about 57 C, the hold needed for a 6.5-log reduction stretches past 4 hours and leaves the validated tables behind, so the odds of Salmonella surviving climb too high.

Why does thickness matter more than weight? Heat conducts inward from every side, and how far the center lags behind the bath comes down almost entirely to the slab thickness, not the total mass of the cut.

Can I rely on color or texture instead? No. Meat that looks pink or translucent at 60 C may be perfectly pasteurized, while fully white meat can still carry pathogens if the hold ran short. Go by a validated time-temperature table.
