Garlic Oil Precautions and Warning

Preparing garlic oil at home and being able to use it to pep up dishes is good, however, note that garlic oil can conduce to several health risks, if it is not prepared and stored properly. Food poisoning due to improper storage is a common hazard. To prevent food poisoning, always refrigerate home-made garlic oil and use it within the next week.
Always use clean, sterilized bottles to store the oil. Label the bottle with the date of preparation. This way you will have an idea of when to discard the oil. Moreover, never store garlic oil at room temperature.
Garlic oil stored at room temperature can result in growth of spores, that cause botulism, thereby spreading toxins in the blood that conduce to illnesses. When garlic is added to oil, the bacteria from the garlic begin to flourish in the oxygen-free oil environment. Thus, it is important to cook the garlic and only then store it.
Cooking the garlic sterilizes it and prevents the chances of bacterial growth. Moreover, never soak garlic into the oil without cooking it. Dunking raw garlic in olive oil may seem the most convenient and easiest method of garlic oil preparation, but it is absolutely dangerous.
As far as commercially prepared garlic oil is concerned, check the labels. Garlic oil in which salt or acids are added are safe and have been preserved well. Just follow the instructions on the label regarding storage.
Garlic oil adds flavor to salad dressings, marinades, vegetable dishes, stir fries, pasta dishes and garlic bread. Besides adding depth to dishes, garlic also benefits the body by its natural antibiotic and immune boosting properties. It is healthy and easy to prepare, however, be careful you make and store the oil properly to avoid food poisoning.
