Bacteria like Staph and Bacillus cereus
can make you sick quickly, within 1 to 7 hours. These bacteria produce fast-acting toxins in foods (such as meat or dairy for Staph, and starchy foods like rice for B. cereus). Keeping such foods refrigerated at 40 °F or colder helps slow or stop the growth of these bacteria.
