,Hepatitis A - Incubation period
15-50 days
Usually 28-30 days
Hepatitis A - Symptoms
loss of appetite, fatigue, nausea, vomiting, abdominal pain, fever, malaise and yellow skin
(jaundice)
K
Hepatitis A - transmission
C
fecal-oral route
Infective: up to 2 weeks before onset to 1 week post-jaundice.
Humans are reservoir.
LO
Hepatitis A - suspect foods
Ice, shellfish contaminated with sewage.
YC
Hepatitis A - exclusion criteria
14 days if no jaundice. 7 days after jaundice onset.
Life-long immunity following recovery.
D
Last 2 - 6 months.
U
Norovirus - incubation period
24-48 hours
ST
Norovirus - symptoms
Sudden onset, watery diarrhea, vomiting, cramp, nausea, low fever.
Norovirus - transmission
Very contagious. Low infective dose. Fecal-oral. Person-Person. Humans only reservoir.
,Norovirus - most at risk
o Children
o Older Adults
o Those with weakened immune systems.
o These higher risk groups are more likely to experience dehydration as a result of severe
vomiting and diarrhea
K
Salmonellosis types
S. enteritis
C
S. typhimurium
LO
Salmonellosis incubation
6-72 hours
Usually 12-36 hours
YC
Salmonellosis symptoms
Sudden onset, cramp, diarrhea, nausea, headache, possible vomit.
D
Salmonellosis transmission
Bacterial. Usually contaminated food, raw bean sprouts. Human and animal reservoir. Pet
U
contact.
ST
Salmonellosis suspect foods
Raw egg, unpasteurized milk, unwashed fruit/veg. Raw meat.
Shigellosis IP
12-96 hours (usually 1-3 days)
, Shigellosis symptoms
Diarrhea, fever, cramp. Nausea.
Possible bloody diarrhea.
May cause HUS in kids.
Shigellosis transmission
Bacterial. Fecal-oral. Sexual contact
Humans only reservoir.
K
Possibly via mechanical vectors (flies, cockroaches)
Low infectious dose.
C
Shigellosis suspect foods
LO
Shigella is not naturally present on foods, but can contaminate food through cross
contamination during handling, or from exposure to polluted water
Food is most often contaminated with Shigella from water polluted by human sewage.
YC
IP - 1-90 days (usually 3-70 days)
Symptoms - Most cases asymptomatic. Fever, headache. <5% vomit & diarrhea.
Transmission: Environmental bacteria. Gets in raw product (between cooking & packaging) &
spreads via cross-contamination.
** Psychrotroph. Hardy.
D
Suspect Foods: Soft cheeses, deli meats, hot dogs, ready to eat meats, unpasteurized milk.
Concern for pregnant women
Listeriosis
U
L. monocytogenes
ST
IP - 0.5-6 hours
Symptoms - Nausea, vomiting, rarely fever and diarrhea
Transmission - Bacterial. Grows and produces heat stable enterotoxin in food.
Suspect foods - Cooked rice left at room temperature
Bacillus Cereus (emetic)
IP - 4-96 hours (usually 12-24)
Symptoms - Severe cramp, watery diarrhea, nausea, vomiting, headache, fever.
