CONTROL OF MICROBIAL GROWTH DURING REFRIGERATED STORAGE Low temperatures slow the rate of each step in the microbial growth cycle, resulting in longer lag phase, slower growth in the exponential phase, and reducing the generation time Some pathogens can grow at low temperatures (Clostridium botulinum type E at 5.5℃; Listeria moncytogenes at 3℃)
