Botulism suspect foods - correct answers o improperly prepared home-canned, low-acid foods
(for example, corn, green beans, peas, asparagus, beets, mushrooms, spaghetti sauce, salmon);
o improperly stored low acid fruit juices (for example, carrot juice);
o leftover baked potatoes stored in aluminium foil;
o honey, which has been linked to cases of infantile botulism and should not be fed to infants
under one year of age.
Campylobacter incubation period - correct answers 1-10 day but usually 2-5 days
Campylobacter transmission - correct answers - through shellfish, raw eggs, unpasteurized dairy
products, untreated water, raw or undercooked meat, raw fruits/veggies
- through contact with infected pets, livestock, animals at a petting zoo, infected person,
rivers/lakes, infected surfaces
Can you boil water or treat with chlorine/UV to make HAB water safe to drink/use? - correct
answers - No, boiling or treating the water will increase the amount of toxins in the water as the
toxins are released when the bacteria is damaged or killed.
- Alternate source of water must be used if testing indicates toxins in water from cyanobacteria.
Can you eat fish that come from a HAB? - correct answers No, toxic levels of bacteria can build
up in fish. Do not eat fish caught in waters experiencing algae blooms and not for two weeks
after it has disappeared.

o meat pies
,o thick soups

prolonged exposure)
, - lung cancer (when symptoms occur it is often late stages)
E. coli exclusion criteria - correct answers - food handlers, daycare, or health care workers
- they should not return to work until 2 negative stool samples taken 24 hours apart and 48
hours after completing antibiotics have been completed
E.coli prevention measures - correct answers - Hand hygiene (when food handling, or around
pets/livestock)
