Foodborne IllnessQuestion 38 of 240

In FAT-TOM, the 'Oxygen' factor matters because different bacteria have different needs. Which pairing is correct?

a.Some bacteria need oxygen (aerobic) while others, like Clostridium botulinum, grow without it (anaerobic)
b.All foodborne bacteria require oxygen to grow
c.No foodborne bacteria can grow without oxygen
d.Oxygen has no effect on bacterial growth

Explanation

Bacteria vary in oxygen needs: aerobic bacteria require oxygen, while anaerobes such as Clostridium botulinum grow in oxygen-free environments like canned or reduced-oxygen-packaged foods. This is why reduced-oxygen packaging and canning create special botulism risks if not controlled. Oxygen clearly does affect which organisms grow.
