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.

Can microorganisms grow?
Yes, and to survive and reproduce they must grow.
How does sugar preserve food?
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.
What is the stage in which microorganisms grow and reproduce?
mitosis
Are Foods that allow microorganisms to grow are called parasites?
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.

What are the effects of micro-organisms on food?
Microorganisms help break down and decompose food. These microorganisms are what cause food to spoil and grow mold on it.
What illness food characteristics affects the ability of microorganisms to grow in food?
density
Food that allow microorganisms to grow are called parasites true or false?
True
Can microorganisms grow?
Yes, and to survive and reproduce they must grow.
What substance can microorganisms grow on?
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

How do microorganisms on food grow and spread so quickly?
Because they try to get away from your mom Because they try to get away from your mom
Why can a dried food be keep longer?
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 bactirea needs to grow?
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.
What Four factors which affect the growth of microorganisms?
Four factors which affect the growth of microorganisms are: temperature food source for microorganisms (ie. sugar, protein, fat) the amount of microorganisms introduced to the food source ph of the food source
Do microorganisms grow?
yes they do, they multiply then grow in 20 mins
Why is foodborne micro-organisms differ from food poisoning micro-organisms?
they reproduce more than food poisoning microorganisms. In food poisoning the microorganisms are spreadable but not in food borne microorganisms :) Hope his helps Janet
