L. monocytogenes
B. cereus
C. perfringens
Which bacteria does NOT cause foodborne illness by infection?
L. monocytogenes
Salmonella sp
E. coli (STECs)
C. perfringens
(Check all that apply). A toxico-infection requires?
a toxin-producing pathogen
live toxin-producing cells, usually in large numbers
dead pathogen cells
spores
This pathogen is considered the target for heat lethality, since it is the most heat resistant.
E. coli (STECs)
C. botulinum
Salmonella
C. perfringens
Staphylococcus aureus
This pathogen is considered the target for spore outgrowth during chilling, since it grows the fastest under these conditions.
E. coli (STECs)
C. botulinum
Salmonella
C. perfringens
Staphylococcus aureus
This pathogen is considered the target for growth under refrigeration.
L. monocytogenes
C. botulinum mesophiles
Salmonella
C. perfringens
Staphylococcus aureus
This pathogen is considered a target for growth under refrigeration in ROP, especially when the food item is fish or seafood.
L. monocytogenes
psychrotrophic C. botulinum
Salmonella
C. perfringens
Staphylococcus aureus
This pathogen is considered the target for growth under low water activity since it grows at the lowest Aw of all of the pathogens (Aw > 0.85).
L. monocytogenes
psychrotrophic C. botulinum
Salmonella
C. perfringens
Staphylococcus aureus
This pathogen is considered the target for growth under low pH since it grows at the lowest pH of all of the pathogens (pH ≥ 4.2).
L. monocytogenes
psychrotrophic C. botulinum
Salmonella
C. perfringens
Staphylococcus aureus
