What slows the growth of bacteria?
The major groups are disinfectants, antiseptics, and antibiotics. Antibacterials are divided into two broad groups according to their biological effect on microorganisms: bactericidal agents kill bacteria, and bacteriostatic agents slow down or stall bacterial growth.
What prevents the growth of germs?
Bacteria enjoy foods that are neutral to slightly acidic. Bacteria like temperatures between 40 and 140 degrees Fahrenheit, and this is known as the Temperature Danger Zone (TDZ). They grow even more rapidly when kept at temperatures from 70 F and 125 F, so you must limit the time foods stay at these temperatures.
What prevents the growth of bacteria in food?
This range of temperatures is called the Danger Zone. Room temperature is usually within the Danger Zone. Bacterial growth slows down or stops in food that is kept at temperatures colder than 5°C or hotter than 63°C.
How can we prevent the spread of microorganisms?
Kitchen
- ensure food-preparation surfaces are clean before use.
- use separate chopping boards for uncooked food – such as raw meat – and food that does not need cooking, like salad leaves.
- wash and dry your hands after handling foods such as raw meat.
- clean surfaces immediately after use.
What are the phases of growth?
There are three phases of growth – meristematic, elongation and maturation.
Why is it important to prevent the spread of germs?
This helps prevent infections because: People frequently touch their eyes, nose, and mouth without even realizing it. Germs can get into the body through the eyes, nose and mouth and make us sick. Germs from unwashed hands can get into foods and drinks while people prepare or consume them.
What is the ideal conditions for bacterial growth?
Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.
