Dear Professor Kwan:
Sorry to bother you. I'm really confused about some questions of 5220.
1. causing severe food borne intoxication during famine?
I suggest maybe V. cholera because of famine but V. cholera is not intoxication.
So, I don't know the right answer.
A: not covered in this year's topics. The microbe is Aspergillus flavus, producing aflatoxin.
2. cats as second hosts and infections in immunocompromised people?
Is it Listeria?
A: not covered in this year's topics. A parasite.
3. Bread, 0.85Aw, 6.5pH, 1.0% salt, -50 redox, moderate sugar and protein, 25
temperature, what kind of bacteria exists in it?
Is Hepatitis A virus possible for this one?
A: Viruses can not grow in food. Aspergillus spp.
4. cabbage, 0.99Aw, 5.2pH, 0.5% salt, 350 redox, moderate sugar and low protein,
15 temperature, what kind of bacteria exists in it?
