Microorganisms in food may cause harm by carrying disease-producing bacteria called pathogens. Pathogens harm humans in many different ways. The most common way that pathogens harm animals is by using toxins.
No, food that allows microorganisms to grow is not called parasites. Instead, such food is often referred to as "perishable" or "spoilable" food, which can support the growth of bacteria, molds, and yeasts. Parasites are organisms that live on or in a host and derive their nutrients at the host's expense, but they are not the same as the microorganisms that can grow in food.
False. Foods that allow microorganisms to grow are not called parasites; they are referred to as "perishable" or "potentially hazardous" foods. Parasites are organisms that live on or in a host and depend on it for nourishment, but they are not the same as the microorganisms that can grow in food.
No. A parasite is an organism that lives at the expense to and causes harm to another organism. Foods that allow microorganisms to grow are media (singular medium).No. If the foods might allow pathogenic microorganisms to grow, they are called potentially hazardous.
Sugar preserves food by lowering the water activity (aw). If the aw is 85 or less, spoilage and pathogenic microorganisms can't grow. Microorganisms all need proper food, water, temperature and acidity to grow and adding sugar to appropriate levels can prevent bacterial growth.
No, that statement is not accurate. Foods that allow microorganisms to grow are typically referred to as "perishable" or "high-risk" foods, not parasites. Parasites are living organisms that depend on a host for survival and can cause disease, while microorganisms include bacteria, yeast, and molds that can thrive in certain food environments. Proper food handling and storage practices can help prevent the growth of harmful microorganisms.

Microorganisms help break down and decompose food. These microorganisms are what cause food to spoil and grow mold on it.

Microorganisms will grow on almost anything organic. Microorganisms need 6 thing to live and reproduce. remember them with the acronym FATTOM Food, the right Acidity, Time, Temperature (40-135 degrees Fahrenheit), Oxygen, and Moisture

Spoilage and pathogenic microorganisms need moisture to grow. When you remove the moisture to below the level that they need, the food will last longer.
What Microorganisms Need to Grow (FAT TOM): FOOD - Proteins and Carbohydrates ACIDITY: Pathogenic bacteria grow best in foods that are slightly acidic (pH of 4.6-7.5) TEMPERATURE: Pathogenic bacteria grow best between 41°F and 135°F (the danger zone). This is why leaving food at room temperature for several hours is very dangerous. Note: Foods left outside the danger zone doesn't necessary kill microorganisms, for example, refrigeration temperature doesn't necessary kill microorganisms but just slow their growth. TIME: When organisms are given favorable temperatures, proper nutrients and water they can double in population as quickly as every 20 minutes. If foods are left in the danger zone for 4 hours or more microorganisms can grow enough to make someone ill. OXYGEN: Some microorganisms need oxygen to grow and some can grow in the absence of oxygen. MOISTURE: Most microorganisms require water to grow therefore they grow well in moist food. Potentially hazardous foods grow best with a .85 or higher water activity level.
