Food Safety and Food Biotechnology

The primary goal of food safety measures is to prevent foodborne illnesses, which are caused by the consumption of contaminated food.

Vitamin C deficiency is not a foodborne illness. It is a nutritional deficiency caused by a lack of vitamin C in the diet.

The 'danger zone' in food safety refers to the temperature range between 40°F and 140°F (4°C and 60°C), where bacteria can grow rapidly and multiply.

All of the options mentioned are critical control points (CCPs) in food safety. CCPs are points in the food production process where hazards can be prevented, eliminated, or reduced to acceptable levels.

Biotechnology plays a multifaceted role in food safety. It contributes to the development of genetically modified crops, food additives and preservatives, and diagnostic tools for foodborne pathogens, among other applications.

GM crops are primarily criticized for potential allergenicity and environmental impact. Concerns have been raised about the potential for GM crops to introduce new allergens or transfer genes to wild plants, leading to ecological disruptions.

Sodium benzoate, potassium sorbate, and calcium propionate are all commonly used food additives that inhibit the growth of bacteria and mold in food.

Food irradiation is a process that uses ionizing radiation to kill bacteria and other microorganisms in food. It is used to extend the shelf life of food and improve its safety.

Leaving cooked food out at room temperature for extended periods is not a recommended practice for preventing foodborne illnesses. Bacteria can grow rapidly in the 'danger zone' between 40°F and 140°F (4°C and 60°C).

The recommended internal temperature for cooking poultry to ensure safety is 165°F (74°C). This temperature kills harmful bacteria that may be present in the poultry.

Norovirus is a common foodborne illness caused by a virus. It is highly contagious and can cause symptoms such as vomiting, diarrhea, and stomach pain.

The primary role of food hygiene in food safety is to prevent contamination of food with harmful microorganisms, such as bacteria, viruses, and parasites.

Fermentation is not a common method of food preservation. It is a process that uses microorganisms to convert carbohydrates into alcohol or acids, which helps preserve food.

The purpose of food labeling in food safety is to provide consumers with information about the ingredients and nutritional value of food, including potential allergens and special dietary considerations.

Thawing frozen food at room temperature is not a recommended practice for safe food handling. It allows bacteria to grow and multiply rapidly.
