Table A. Interaction of pH and aw for control of spores in food heat treated to destroy vegetative cells and subsequently packaged | |||
Aw values | pH | ||
4.6 or less | 4.6 - 5.6 | 5.6 | |
0.92 | non-PHF*/non-TCS food** | non-PHF/non-TCS food | non-PHF/non-TCS food |
0.92- 95 | non-PHF/non-TCS food | non-PHF/non-TCS food | PA*** |
0.95 | non-PHF/non-TCS food | PA | PA |
* PHF means potentially hazardous food ** TCS food means time/temperature control for safety food *** PA means Product Assessment required |
