Hepatitis A, Norovirus Gastroenteritis

What type of people are the highest risk for foodborne illnesses?

Infants+ preschool-age children, pregnant women, elderly people, people taking certain medications, people who are seriously ill

Info about Cryptosporidius

Infection, Parasite= Cryptosproridium parvum. Commonly associated food: untreated or improperly treated water, and contaminated produce. Most common symptoms: watery diarrhea, stomach cramps, nausea, and weight loss.

Info about Norovirus Gastroenteritis

Infection, Virus: Norovirus. Commonly associated food: ready-to-eat food, shellfish contaminated by sewage. Most common symptoms: vomiting, diarrhea, nausea, abdominal cramps

Information about Salmonellosis

Infection: bacteria= Salmonella spp. ; commonly associated foods: poultry and eggs, dairy products, beef, and spinach; most common symptoms: diarrhea, abdominal cramps, vomiting, fever

Info about Cyclosporiasis

Infection: bacteria=Cyclospora caytanensis. Commonly associated food= produced irrigated or washed with water containing the parasite. Most common symptoms: nausea (mild to severe), abdominal cramping, mild fever, diarrhea alternating with constipation

How to prevent Listeriosis

It is critical to: discard product that has passed its use-by or expiration date and avoid using unpasteurized dairy products. To reduce the bacteria in food: cook raw meat to required minimum internal temperatures. To prevent the transfer of the bacteria: Prevent cross-contamination between raw or undercooked and ready-to-eat food.

Preventing Cyclosporiasis

It is critical to: purchase produce from approved, reputable suppliers. To prevent the transfer of the parasite to food: exclude foodhandlers with diarrhea, and wash hands properly to minimize the risk of cross-contamination

Shellfish toxin illnesses

Paralytic Shellfish Poisoning (PSP), Neurotoxic Shellfish Poisoning (NSP), Amnesic Shellfish Poisoning (ASP).

How to prevent Hemorrhagic Colitis

To prevent the bacteria in food: cook food, particularly ground beef, to required minimum internal temperatures. To prevent the transfer of the bacteria to food: -prevent cross-contamination between raw meat and ready-to-eat food. -exclude employees from the establishment if: they have diarrhea, they have been diagnosed with hemorrhagic colitis

How to prevent Staphylococcal Gastreoenteritis

To prevent the transfer of the bacteria to food: wash hands after touching the body, cover cuts on hands and arms, restrict foodhandlers with infected cuts on hands and arms. To prevent the growth of the bacteria of the bacteria in food: Minimize the time food spends in the Temperature Danger Zone- cook, hold, and cool food properly

How to prevent Shigellosis

To prevent the transfer of the bacteria: exclude foodhandlers if they: have diarrhea, have been diagnosed with shigellosis; wash hands when necessary, control flies inside and outside the establishment

What type of microorganisms contaminate food and cause foodborne illness?

bacteria, viruses, parasites, fungi

What are spores

certain bacteria can change into spores to protect themselves (when nutrients are not available); can resist heat, allowing them to survive cooking temperatures, and can revert back to a form capable of growth when food is not stored at the proper temperature/food is not properly held or cooled properly

Info about Scombroid poisoning

what is a parasite?

illness-causing micro-organism

What is a foodborne-illness outbreak?

incident in which two or more people experience the same illness after eating the same food

prevention of cryptosporidius

it is critical to: Purchase produce from reputable, approved suppliers + use properly treated water. To prevent the transfer of the parasite to food: Exclude foodhandlers with diarrhea and wash hands properly to minimize the risk of cross-contamination

Symptoms of an allergic reaction

itching in/around the mouth/face/scalp, tightening in the throat, wheezing or shortness of breath, hives, swelling of the face, eyes, hands, or feet, Gastrointestinal symptoms, loss of consciousness and death
