FAT TOM is an mnemonic device used in the food industry to describe what conditions foodborne bacteria need to grow:Food - sufficient nutrients needed to promote pathogen growth such as food high in protein and carbsAcidity - pathogens require a pH between 4.6 and 7.5 to growTime - food should be removed from the TDZ (below) within two hoursTemperature - pathogens grow most between 5°C to 57°C, a range known commonly as the "temperature danger zone", or TDZOxygen - almost all pathogens are aerobic, or require oxygen to grow; however, some are anaerobicMoisture - bacteria grow best in foods with a water activity (aw) levels between 1.0 and 0.86
we have some germs but if we get sick the germs go through the mouth and pathogens grow because the sick person care about you than there germs go to your germs yuck!
The six conditions in which pathogens need to grow are as follows: FAT TOM Food: to grow pathogens need an energy source. Carbohydrates, such as baked potatoes, and proteins, such as beef are some examples. Acidity: Pathogens grow best in food that contains little or no acid. An example of food with a lot of acid is lemons. Food items with little acid include chicken and cooked corn. Temperature: Pathogens grow well in food that as a temperature between 41 degrees Fahrenheit and 135 degrees Fahrenheit. This range is known as the temperature danger zone. Time: Pathogens need time to grow. When food is in the temperature danger zone, pathogens grow. After four hours, they will grow to levels high enough to make someone sick. Oxygen: Some pathogens need oxygen to grow. Others grow when oxygen isn't there. For example, some pathogens that grow without oxygen would grow quickly in cooked rice. Moisture: Pathogens need moisture in food to grow. For example, tomatoes and melons have a large amount of water in them, which means they can easily support the growth of pathogens.
Thousands of types of bacteria are naturally present in our environment. Microorganisms that cause disease are called pathogens. When certain pathogens enter the food supply, they can cause foodborne illness. Not all bacteria cause disease in humans. For example, some bacteria are used beneficially in making cheese and yogurt.
yes it is true that some bacterias are not pathogens
Some are, some aren't. Parasites are pathogens and can be quite large in some cases.
Not always. Pathogens such as viruses must attack human cells to replicate. Other pathogens like bacteria can actually attack and distroy tissue or just cling onto the surface. (For example: Clostridium Difficile is a bacteria that can grow out of control in a person's colon; they cling to the walls and prevent the absorption of fluids, this results in diarrhea.) Some bacteria produce toxins that attack tissues.Yes some pathogens attack human tissue.Yes
There are probably some molds that won't grow in the refrigerator, but anyone who has cleaned out a neglected fridge can tell tall tales about moldy food they have found there.
Yes, pathogens are agents capable of causing infections or some types of diseases. Pathogens are normally on our skin and any objects without causing problems. Not all pathogens succeed in their goal to find a host, but many pathogens do.
Trichina and Brucella are two examples of zoonotic foodborne microorganisms. Note that it's not too surprising to find a nematod in the mix as they're premier parasites. Note also that I'm bending the rules on calling Trichina a microorganism -- I believe the larvae are, but the adult is visible with the naked eye. Bacteria, viruses, parasites and protozoa can also be foodborne. Some of the more famous bacteria are Salmonella and Listeria. Norovirus is a well-know foodborne virus. Giardia is a parasite that is found in water and can affect campers.
The "best" temperature actually depends on the type of bacteria and even the strain. The bacteria of Public Health significance tend to grow between 135°F and 40°F. But some Listeria will actually grow at 32°F.
