2.) Explain several different ways in which foods can become contaminated and how this can be prevented. Describe the symptoms of food poisoning and other illnesses that can result from ingesting contaminated food. What treatments are available?

Hepatitis A - Hepatitis A is a liver infection caused by the hepatitis A virus that can be prevented by a vaccine (HAV). HAV is present in the stool and blood of infected individuals. It is transmitted when a person unknowingly ingests the virus by near physical contact with an infected person or by consuming tainted food or drink. Hepatitis A symptoms include fatigue, nausea, stomach pain, and jaundice, which can last up to two months.

Hepatitis B -  Hepatitis B is a liver infection caused by the hepatitis B virus that can be prevented by a vaccine (HBV). Hepatitis B is transmitted when blood, sperm, or other bodily fluids from a virus-infected human touch the bloodstream of an uninfected individual. Yellowing of the skin, stomach pain, and black urine are some of the symptoms. Liver disease, cancer, or scarring may occur in chronic cases.

Hepatitis C - A virus-borne infection that affects the liver and causes inflammation. Communication with infected blood, such as by exchanging needles or using unsterile tattoo devices, spreads the infection. The majority of patients have no signs or symptoms. Those who may have symptoms may experience exhaustion, nausea, lack of appetite, and skin and eye yellowing. Antiviral drugs are used to treat hepatitis C.

Food contamination, prevention, ect.

-Raw food ingredients have the potential to contaminate food, kitchen appliances, and surfaces. Through using the same knife, cutting board, or other utensil repeatedly without cleaning the surface or utensil between uses, microbes may be moved from one food to another.

-Wash your hands, Wash worktops, knives and utensils, Wash dishcloths, Use separate chopping boards, Keep raw meat separate, Store raw meat on the bottom shelf, Cook food thoroughly, Keep your fridge below 5C.

- Nausea, vomiting, and diarrhea are the most frequent signs of food poisoning. Food poisoning can be caused by bacteria, parasites, and viruses. Based on your signs, your doctor will be able to determine the sort of food poisoning you have. In severe cases, blood tests, stool tests, and tests on food that you have eaten may be conducted to determine what is responsible for the food poisoning.

- Many forms of food poisoning should be treated at home, and most cases can clear up in three to five days. It's important to keep yourself hydrated. Electrolyte-rich sports drinks can be beneficial in this regard. Fruit juice and coconut water can assist with exhaustion and carbohydrate replenishment. Imodium and Pepto-Bismol are two over-the-counter drugs that can help control diarrhea and nausea.
