what is the best way to cook hamburgers that you want to reheat the next day? As long as ground meat is heated to above 71C/160F as measured with a food thermometer in the slow cooker it will be safe. Browning the meat before putting it in the slow cooker enhances the flavour and colour. We use a rice cooker almost every other day. How long is it safe to eat the rice that remains in the cooker on the warm setting of the steamer. The safety depends on the temperature of the rice when your cooker is on the warm setting. To be safe, the rice should be warmer than  60C/140F to prevent harmful bacteria from growing such as Bacillu cereus known to contaminate rice and produce spores resistant to heat. Test the temperature with a food thermometer. If you cannot maintain that high temperature, the rice should be refrigerated within two hours from its cooking.  To be sure all the rice is at a safe temperature, it should be stirred often. I have found in my freezer at minus 18, some chicken breasts that have been there for 2 years.  They still look good and do not seem to have any freezer burns.  Can we eat them or would we be sick? The recommended maximum time for storage of chicken pieces in the freezer is six months. If stored longer there will be gradual loss of quality and there may be food safety issues. Is it ok for
