1. UNIT II LESSON 1: FOOD AND SAFETY HYGIENE

2. INTRODUCTION TO HEALTHY EATING Healthy eating involves choosing a variety of foods that provide the nutrients you need to maintain your health, feel good, and have energy. These nutrients include protein, carbohydrates, fat, water, vitamins, and minerals.

3. COMMON FOODBORNE ILLNESSES AND THEIR PREVENTION.

4. “FOODBORNE ILLNESSES” an umbrella term that describes any illness caused by consuming foods or beverages contaminated with harmful pathogens such as bacteria, viruses, and fungi — or their toxins. can occur if you eat foods that contain live bacteria or other pathogens. These pathogens can later grow in your gut and cause symptoms such as abdominal cramping, diarrhea, and vomiting.

5. CAUSES OF FOODBORNE ILLNESSES Bacteria : These may be present in raw and undercooked meat, fish, and poultry; unpasteurized dairy products; contaminated fruits and vegetables; and contaminated drinking water.

6. Viruses : Viruses are transmitted to the body through food contaminated by viral particles.

7. Parasites : Contaminated water and soil can transmit harmful parasites to fresh produce, seafood, meat, poultry, and other foods.

8. Prions : These infectious proteins are associated with “ mad cow disease ” and can come from eating parts of cattle, such as the brain tissue.

9. Naturally occurring chemicals : Naturally occurring toxins in mushrooms, staple foods such as corn and cereal, and mold on grains can cause long-term health complications.

10. Environmental pollutants: By products of plastic production and waste management, as well as heavy metals such as lead and mercury found in water and soil, can contaminate foods and lead to foodborne illnesses.

11. Campylobacteriosis Type: Bacteria Food Sources: raw or undercooked poultry, seafood, and meat • contaminated drinking water Symptoms: • bloody diarrhea • fever • stomach cramps Duration: 1 week Some examples of foodborne illnesses?

12. Giardiasis Type: Parasite Food Sources: food and drinking water contaminated with feces Symptoms: • dehydration • flatulence (gas) • nausea • vomiting • diarrhea Duration: 2–6 weeks Some examples of foodborne illnesses?

13. Norovirus Type: Virus Food Sources: foods harvested with feces-contaminated water (fruits, vegetables, oysters) Symptoms: • diarrhea • nausea • vomiting • stomach cramps Duration: 2 weeks Some examples of foodborne illnesses?

14. Escherichia coli Type: Bacteria Food Sources: contaminated drinking water, vegetables, ground meat products, raw milk. Symptoms • stomach cramps • diarrhea • vomiting • fever Duration: 5-7 days Some examples of foodborne illnesses?

15. Toxoplasmosis Type: Parasite Food Sources: undercooked or contaminated pork, lamb, venison, and shellfish Symptoms • muscle pain and aches • blurred visions • eye pain • miscarriage Duration: Weeks to month Some examples of foodborne illnesses?

16. Listeriosis Type: Bacteria Food Sources: soft cheeses, fruits, vegetables, deli meat, hot dogs Symptoms • diarrhea • vomiting • fever • muscle aches • fatigue • headache • loss of balance Duration: Days to weeks. Some examples of foodborne illnesses?

17. Botulism Type: Bacteria Toxin Food Sources: • improperly canned, preserved and fermented foods, honey Symptoms • muscle weakness • difficulty swallowing • difficulty breathing • impaired vision Duration: Several weeks. Some examples of foodborne illnesses?

18. Anisakiasis Type: Parasite Food Sources: raw or undercooked fish and squid Symptoms • abdominal pain and bloating • nausea • vomiting • anaphylaxis Duration: 3 weeks Some examples of foodborne illnesses?
