Salmonella bacteria are killed by temperatures above 55Â°C (130Â°F). The rate at which bacteria are destroyed depends on temperature, species, acidity (pH), and humidity (Angelotti et al. ).Ten minutes at 65Â°C (150Â°F), or less than two minutes at 70Â°C (160Â°F), are both about as effective as an hour at 60Â°C (140Â°F). refrigerator set at 4Â°C 40Â°F or below will protect most foods from immediate spoilage; cooking to 60Â°C 140Â°F and above will kill almost all organisms. However, many bacteria are psychrotrophic âthese remain active at refrigerator temperatures.
