What Freezing Temperature Kills Salmonella?
Freezing food at a temperature of at least 0°F for at least 7 days kills salmonella.
Quick Tips and Facts:
1. The freezing temperature that is lethal to salmonella bacteria is -4 degrees Fahrenheit (-20 degrees Celsius). At this temperature, the bacteria’s cell structure becomes damaged, rendering it unable to survive and reproduce.
2. Despite being vulnerable to freezing temperatures, salmonella bacteria can actually survive in frozen food for long periods. Freezing merely puts the bacteria into a dormant state, allowing it to become active once the food is thawed.
3. Salmonella can be found in various food sources, including raw poultry, eggs, unpasteurized milk, and even certain fruits and vegetables. It is essential to take proper precautions, such as thorough cooking and practicing good hygiene, to prevent its transmission.
4. Freezing is not the only method to eliminate salmonella bacteria from food; cooking at high temperatures can also be effective. The recommended internal temperature for poultry, for instance, is 165 degrees Fahrenheit (74 degrees Celsius), as this kills any potential salmonella bacteria present.
5. Research has shown that salmonella bacteria can survive for longer durations at lower freezing temperatures. At -13 degrees Fahrenheit (-25 degrees Celsius), the bacteria can survive for up to six months, while at -4 degrees Fahrenheit (-20 degrees Celsius), they can persist for approximately one month.
