Why Should Raw Meat Be Stored on the Bottom Shelf of the Fridge?

Raw meat should be stored on the bottom shelf of the refrigerator because any meat juice that leaks from its packaging drips downward; if the meat sits on a top shelf, that liquid can reach every shelf below it and the food sitting there, while on the bottom shelf there is nothing left underneath for it to drip onto. Why is cross-contamination especially risky with raw meat? Raw meat and poultry can carry far more bacteria than vegetables, fruit or ready-to-eat food that will not be cooked before eating. Those bacteria are neutralized by the high heat of cooking, but a drop of liquid that leaks from raw meat while it is still raw can land on a cooked dish or a vegetable meant to be eaten as is, and stay active on that food. Why is the bottom shelf the safest spot? The bottom shelf of a refrigerator is the best spot for raw meat both because there is no food sitting beneath the drip path and because it is usually the coldest part of the refrigerator. Even if a leak happens, that liquid will not touch any other food as long as it stays inside the tray or container. Is placing a container or tray underneath the meat enough on its own? Keeping raw meat in a sealed container or a tray with raised edges cuts the risk significantly, but it is not enough on its own; packaging can tear or a tray can overflow. That is why keeping it in a suitable container and placing it on the bottom shelf together means using two precautions at once. What should sit on the upper shelves? The upper shelves should be reserved for food that will be eaten as is: leftovers, dairy products, and washed fruit and vegetables that will not be cooked belong on the top and middle shelves. This layout removes the chance of a leak from raw meat reaching food that will be eaten without further cooking. Should different types of raw meat be kept apart? Red meat, poultry and fish should be kept on different shelves or at least in separate containers; poultry in particular carries a higher bacterial risk than other meats, so where possible it should sit on the bottom shelf in its own compartment. That separation also keeps bacteria from one type of meat from reaching another. Is packaging from the store protection enough on its own? Most meat packaging from the store is designed for short-term transport and is not always fully leak-proof; a small tear or hole at a corner is a fairly common flaw. That is why, instead of trusting the packaging alone, placing it inside an extra container before putting it in the refrigerator is a simple step that doubles the safety margin. Does the same rule apply in the freezer? In the freezer, the risk of leaking is much lower since the meat stays frozen solid, but the same rules apply from the moment it starts to thaw. That is why meat taken out of the freezer to thaw in the refrigerator should sit on the bottom shelf, inside a container, from the very start of the thawing process.
