A As microwave cooking times are much shorter than other cooking times, it is essential that recommended cooking times are not exceeded without first checking the food.

B Take care when heating small amounts of food as these can easily burn, dry out or catch fire if cooked too long. Always set short cooking times and check the food frequently.

C Take care when heating 'dry' foods, e.g. bread items, chocolate and pastries. These can easily burn or catch fire if cooked too long.

D Some processed meats, such as sausages, have non-porous casings. These must be pierced by a fork before cooking, to prevent bursting. Whole fruit and vegetables should be similarly treated.

E When heating soup, sauces and beverages in your microwave oven, heating beyond boiling point can occur withoL•t evidence of bubbling. Care should be taken not to overheat.

F When warming up food for a second time, it is essential that it is served 'piping hot', i.e. steam is being emitted from all parts and any sauce is bubbling. For foods that cannot be stirred, e.g. pizza, the centre should be cut with a knife to test it is well heated through.

G It is important for the safe operation of the oven that it is wiped out regularly. Use warm, soapy water, squeeze the cloth out well and use it to remove any grease or food from the interior. The oven should be unplugged during this process.
