Explanation:

1. Foodborne illnesses are diseases caused by consuming contaminated food or beverages.
2. Bacteria are single - celled microorganisms. They can be found in raw meats, dairy products, and eggs.
3. Food can be contaminated through contact with dirty hands, unclean surfaces, and contaminated water. For example, handling raw meat and then touching ready - to - eat food without washing hands, using a cutting board for raw meat and then for vegetables without proper cleaning, and using contaminated water to wash produce.
4. Bacteria multiply through binary fission. They multiply well in the temperature danger zone of 40°F - 140°F (4°C - 60°C). Refrigeration and freezing slow down their multiplication. High heat (cooking to proper temperatures) can kill bacteria.
5. Salmonella is a bacterium that can cause diarrhea, fever, and abdominal cramps, often found in raw or undercooked poultry, eggs, and meat. E. coli can cause severe stomach cramps, diarrhea, and vomiting, and can be present in undercooked beef, raw vegetables, and contaminated water. Listeria can cause fever, muscle aches, and in severe cases, can be life - threatening, and is found in soft cheeses, cold cuts, and unpasteurized milk.
6. Foodborne viruses are viruses that are transmitted through food. They can be obtained from contaminated water or food. Examples include norovirus (from shellfish and contaminated water) and hepatitis A (from raw or undercooked shellfish and contaminated produce).
7. A parasite is an organism that lives on or in another organism (the host) and benefits at the host's expense.
8. Chemicals can contaminate food through agricultural practices (pesticides, fertilizers), industrial pollution (heavy metals in water or soil), and improper food processing (additives in excess).
9. The target groups for foodborne illness include young children, the elderly, pregnant women, and people with weakened immune systems.
10. Symptoms of foodborne illness include nausea, vomiting, diarrhea, abdominal pain, fever, and chills.
11. Dehydration is the excessive loss of body water. It is dangerous because it can lead to electrolyte imbalances, kidney failure, and in severe cases, death. Signs of dehydration include dry mouth, thirst, dark - colored urine, and fatigue.
12. It is important to see a doctor if you have a foodborne illness because they can diagnose the cause, provide appropriate treatment (such as rehydration therapy, antibiotics if bacterial), and prevent complications.
13. Foodborne illnesses are diagnosed through stool samples, blood tests, and sometimes imaging. Treatment depends on the cause (antibiotics for bacterial, supportive care for viral). Prevention includes proper food handling (washing hands, cooking food to proper temperatures, storing food correctly).

Answer:

1. Diseases caused by consuming contaminated food or beverages.
2. Single - celled microorganisms; raw meats, dairy products, eggs.
3. Contact with dirty hands, unclean surfaces, contaminated water; handling raw meat then touching ready - to - eat food without hand - washing, using a cutting board for raw meat then for vegetables without cleaning, using contaminated water to wash produce.
4. Through binary fission; 40°F - 140°F (4°C - 60°C); refrigeration and freezing; high heat (cooking to proper temperatures).
5. Salmonella: diarrhea, fever, abdominal cramps, in raw or undercooked poultry, eggs, meat. E. coli: severe stomach cramps, diarrhea, vomiting, in undercooked beef, raw vegetables, contaminated water. Listeria: fever, muscle aches, life - threatening in severe cases, in soft cheeses, cold cuts, unpasteurized milk.
6. Viruses transmitted through food; from contaminated water or food; norovirus (shellfish, contaminated water), hepatitis A (raw or undercooked shellfish, contaminated produce).
