This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - FAT TOM is a mnemonic for the six conditions bacteria need to grow: Food, Acidity, Time, Temperature, Oxygen, and Moisture. - The FDA Food Code defines the temperature danger zone as 41°F to 135°F, the range where pathogens multiply most rapidly. - TCS foods can only be exposed to the temperature danger zone for a cumulative maximum of four hours before they must be discarded. - Bacteria thrive in a neutral to slightly acidic environment with a pH between 4.6 and 7.5. - Foods with a high water activity (aw) of 0.85 or greater provide sufficient moisture to support bacterial growth.
