Garlic, onion, allspice and oregano, for example, were found to be the best all-around bacteria killers (they kill everything), followed by thyme, cinnamon, tarragon and cumin (any of which kill up to 80 percent of bacteria).
Salmonella Approximately 1 million people are sickened by Salmonella in the U.S. each year and approximately 380 of them die from the infection. Children are at the highest risk for Salmonella infection. Children younger than 5 have higher rates of Salmonella infection than any other age group.
Boiling does kill any bacteria active at the time, including E. coli and salmonella.
Proper heating and reheating will kill foodborne bacteria. However, some foodborne bacteria produce poisons or toxins that are not destroyed by high cooking temperatures if the food is left out at room temperature for an extended period of time.
To start with, raw meat may be contaminated with spores of certain pathogenic bacteria (e.g. Clostridium perfringens) and spores are not readily destroyed by normal cooking temperature.
This vibration causes friction, which allows the object to heat up to a temperature that can kill germs. That's why microwaves are sometimes used to disinfect items such as a household sponge, as they are a hotbed for viruses and bacteria.
The World Health Organization (WHO) notes that bacteria are rapidly killed at temperatures above 149°F (65°C). This temperature is below that of boiling water or even a simmer.
Moist heat sterilization, i.e., sterilization by heat combined with moisture is one of the most effective methods of killing microorganisms. Moist heat kills microorganisms by coagulating their proteins and sterilizes the equipment's, etc. quite rapidly.
Despite this, a certain level of applied heat and contact time can kill the majority of foodborne illness-causing bacteria in food. In general, an average hot temperature of 165°F (74°C) in cooking can eliminate most of the harmful bacteria in food.
Bacteriophages are, therefore, the natural enemies of bacteria. In nature, both bacteria and bacteriophages are necessary to keep microscopic ecosystems working properly.
Bacteria enjoy foods that are neutral to slightly acidic. They will not grow in highly acidic foods like lemons and vinegars, but will grow well in vegetables, meat and some fruits. Temperature needs to be considered for bacterial growth.
Disinfectant: usually a chemical agent (but sometimes a physical agent) that destroys disease-causing pathogens or other harmful microorganisms but might not kill bacterial spores.
There are no antibiotics for most E. coli infections. If you have contracted traveler's diarrhea, your doctor may recommend that you do take anti-diarrhea medications for a short period or bismuth subsalicylate (Pepto-Bismol). In some instances, doctors treat the infection with antibiotics.
If you don't have safe bottled water, you should boil your water to make it safe to drink. Boiling is the surest method to kill disease-causing germs, including viruses, bacteria, and parasites.
Freezing does not kill germs and bacteria. Instead, it essentially puts them into hibernation. They are inactive while the food is frozen and will “wake up” as soon as the food thaws. And as the food thaws, so will the moisture, which means the bacteria will have the moisture it needs to survive.
Chicken. Chicken tends to be responsible for the most foodborne illnesses, but that is likely because it's the kind of meat we eat the most. Many cases of food contamination come from the mishandling of meats and cross-contamination in our own kitchens.
Dangerous bacterial growth occurs between 41 and 135 degrees F. This spectrum is known as the danger zone for foods. Potentially harmful bacteria grows most rapidly at these temperatures. Placing large batches of hot foods in the fridge can raise the temperature of the fridge into this danger zone.
Because deep fat frying involves using extremely hot oil to cook foods, it is a fast process and helps to kill any bacteria in the food — when done properly.
