What temperature inhibits the growth of Salmonella?

What temperature inhibits the growth of Salmonella?

• A. 40 degrees Fahrenheit or lower
• B. 60 degrees Fahrenheit
• C. 20 degrees Celsius
• D. 100 degrees Fahrenheit

Answer: (A)

The main idea is how temperature affects Salmonella growth. Salmonella multiplies best in warmer conditions, especially in the “danger zone” roughly between 40°F and 140°F. Refrigeration at 40°F (4°C) or lower slows metabolism so much that replication is inhibited, effectively stopping growth. At higher temperatures like 60°F, 68°F (20°C), or 100°F (38°C), Salmonella can still grow, just more slowly or more quickly depending on conditions, so those temperatures don’t inhibit growth.
