Food-borne diseases, bacteria

Types of bacteria

Bacteria are around us, air, water, wax, our skin and body. They are classified in a variety of ways, but our purpose we can classify them as Basic.

Most of the harmful bacteria-bacteria belong to this category. They also help us and are harmful to us. These bacteria have a specific purpose, but they are not relevant to us in terms of food safety,

Bacteria-believe it or not some bacteria help us. Some bacteria are used to make cheese food the United States. And still others live in our bodies to fight harmful bacteria.

Bacteria unwanted bacteria is responsible for food spoilage. This type of bacteria that cause no ill, but they show themselves using smells, sticky or slimy and discoloration of bruises.

This makes it impossible to know whether food or by the Act of smelling or tasting or looking at it. The only way to protect yourself against this bacteria is by appropriate food handling and sanitation.

Growing bacteria

Bacteria multiply just by splitting in two. Ideally, they can double in number every 15-30 minutes. This means that an individual bacterium one multiply million less than 6 hours.

What you need bacteria multiply?

Food-food is a basic requirement for bacteria to grow.

Moisture-water required for bacteria to absorb food. Dry food will not support bacterial growth. Even foods with a high content of salt or sugar become bacteria can use moisture present.

Bacteria grow most temperature-temperature hot water between 40 to 140 ° f temperature range, this is what we call my risk of food.

-Most of the bacteria require oxygen to grow, but not all. There are some exceptions, one type of bacteria is botulism.

Time when introduced to a new environment, bacteria, they need time to adjust before they start to grow. This time is called the phase delay and last about an hour.

How is the bacteria that are passed?

Bacteria are one place to another by being performed. This may happen by other peoples hands, food, utensils, equipment, water, or harmful.

Preventing the growth of bacteria

Now that we know how bacteria spread sizes; We should be able to prevent food-borne illnesses by following three simple steps.

1. keep the bacteria do not span multiple by which may contain bacteria that is difficult. This includes the people, equipment, utensils and other perhaps.

2. stop the bacteria grow by taking the conditions that encourage growth. The most effective way is to keep food from danger. Keep foods below 40 ° F and 140 ° f

3. Finally kill the bacteria. Most bacteria are killed if they are subject to temperatures above 80 ° F for 30 seconds. This is how we make food safe by cooking. This heat is also how we sanitize dishes and equipment. Certain chemicals (such as bleach) also kill bacteria. By sanitizing agents is the best to sanitize counter tops big equipment.
