Problem: Write an article based on this summary: Take out a blank, clean sheet of paper. Rub discolored areas on the eraser against your paper. Persist erasing until your eraser is clean all over. Use an eraser case or cover for storage. Repeat this process regularly as build-up occurs.

Answer: Any piece of normal paper should do for the purposes of cleaning your eraser. You should avoid paper with a glossy finish, as this kind will be less fibrous. Less fibrous paper could result in your eraser gunk smearing over more of your eraser making more work for you. Paper that is coarse and heavy will allow you to scrub it harder with your eraser without fear of tearing the paper. Coarse paper will also cause your eraser to come apart from the eraser in flecks or eraser shavings. This is ideal, as these shavings will part the gunk from the rest of your paper. You should avoid writing on paper that already has writing on it, including words that have been printed onto paper with a computer printer. The ink from the printer, from pens, or graphite from pencils could cause more gunk to build up while you're trying to remove it. Printer paper, while somewhat smoother than an ideal sheet of eraser purifying paper, should work well enough for purging gunk from your eraser. This paper also has the added benefit of being bright white in color. This will make it easier to tell when your gunk is gone and the eraser erases clean. Inspect your eraser carefully and note the areas that are discolored. These are the areas you will want to target. When the dark spots on your eraser have been removed, your eraser should erase as good as new. Rub your eraser firmly against the clean paper you have chosen and be sure you avoid crossing over the darkened marks that rub off on your paper. Feel the eraser gunk with your fingers. Sometimes the graphite gunk will be soft, like putty. In this case, you might be able to cut through some of the gunk with your fingers or nails. Be careful not to spread the gunk around or push it deeper into the eraser with your fingers. Doing so will make your eraser cleaning more difficult. As you scrub your eraser on the clean page, eraser shavings should come free of the eraser, and with these so too should come the graphite gunk. Brush away shavings regularly to prevent them and the gunk they contain from re-smudging your eraser. A drafting table or an angled desk will allow the force of gravity to help pull many of the shavings free of your paper. You might also hold your paper flat against a wall to get the maximum gravity assistance. You might also need to switch paper, depending on the size of your eraser and the amount of gunk built up on it. When it becomes difficult to rub your eraser on the page without crossing one of the darkened smears, you should get a new piece of paper. A case will protect your eraser from the drying effects of the air or the decay that can be caused by too much moisture. But you don't need a special case to prolong the life of your eraser! Even a normal pencil case can keep dust and other residue from negatively impacting your eraser's efficiency. You can find specialty eraser cases at your local art supply store or through an online retailer. You should especially consider a specialty case if you are an artist and use expensive, high quality erasers for your art. You might store your erasers in a tupperware container, or some other kind of clean, plastic container. This will limit its exposure to harmful elements, like air, dust, and moisture. Keep your erasers separate from your pencils, crayons, and pens. These items can carry dust and grime, or in some cases can create dust and grime, that can hurt your erasers performance. Keep a separate container for your erasers to prevent this. If you are an artist and use your eraser frequently, you may need to purge your eraser of blemishes fairly regularly. But even occasional pencil/eraser users may have to repeat this process several times over the life of the eraser. By purging your eraser of graphite gunk, you will save yourself money and maintain the immaculate quality of your work. If you have a low quality eraser or a soft lead pencil that accumulates gunk quickly, you may want to carry a folded up sheet of clean paper in your eraser case to use on the fly.

Problem: Write an article based on this summary: Shop Maintain the cold chain. Always wash your hands before and after preparing foods. Keep your kitchen clean. Use separate chopping boards for preparing raw meat/poultry and vegetables. Defrost carefully. Cook foods thoroughly. Keep hot foods hot and cold foods cold. Reheat leftovers thoroughly before serving.

Answer:
with care. Food safety begins at the grocery store, so make sure to shop wisely: Check the use-by dates on all products and use your judgement to decide if foods have been stored at the correct temperatures. Pack meat and poultry products into separate bags and do not let the raw flesh touch any other food products as you shop or bring them home. Keep cold and frozen foods as cold as possible, especially when transferring from the store to your home. This prevents the growth of pesky bacteria that could cause food poisoning. Here are ways to keep your food safe: Wrap the goods in newspaper or buy a small cooler bag to transport your cold and frozen foods home. When using coolers, always separate meat from other cold items. You should label your coolers so you always put the right items in the right cooler. Clean the coolers after each use with disinfecting cloths. When possible, leave grabbing cold products to the end of your shopping. Store all foods properly and quickly when you get back home. Wash your hands thoroughly with hot water and antibacterial soap before and after preparing food, especially after handling raw meat. Dry your hands on a clean towel that's separate from the 1 you use to wipe down surfaces. Keep dish cloths and hand towels regularly cleaned to prevent bacteria from accumulating on the fabric. Always wash your hands after handling pets (especially reptiles, turtles and birds) and after using the bathroom or handling pet litter. It's very important to keep your kitchen counters and other food preparation areas clean, especially when preparing high-risk food items like meat, poultry and eggs. Use a mild disinfectant to clean your countertops and other surfaces. Wash your cutting board in warm, soapy water. It's best to also clean it using a bleach solution made of 1 teaspoon (5 mL) of bleach mixed into 34 ounces (1 L) of water. Disinfect your sink, especially if you've washed raw meat products in it. It's possible for germs to get on your clean dishes. Keep these boards separate to avoid any possibility of cross-contamination of bacteria from meat to other food products. If you cannot keep separate chopping boards, make sure to disinfect a multi-purpose chopping board thoroughly after each use (see bleach recipe in "Tips"). Plastic chopping boards are recommended over wooden chopping boards, as the wooden ones are harder to clean. Wooden chopping boards can also absorb and hold bacteria in their grain. You should never defrost food (especially meat and poultry) at room temperature just to speed up the process. Food should always be thawed in the refrigerator, as thawing at room temperature allows the surface of the food to warm up too quickly, promoting bacteria growth. Alternatively, you can defrost foods using the "defrost" or "50 percent power" setting on your microwave. You can also safely defrost food by holding them under cold running water. Once foods have been completely thawed, they should be used promptly -- they should never be refrozen without being cooked first. This is especially important for red meat, poultry and eggs, which are considered high-risk foods. Cooking these foods all the way through will destroy harmful germs. Consult a cookbook for the correct cooking times (taking the weight of the food and the temperature of your oven into account). Use a meat thermometer if you have any doubts about how long to cook something -- this can take a lot of the uncertainty out of cooking meats. Chicken and turkey are cooked when they reach a temperature of 165F, steaks are cooked at 145F and hamburgers are cooked at 160F. Bacteria multiply fastest between 40F and 140F, so it's important to keep foods either above or below these temperatures. You should make sure your fridge is set at a temperature of 4C/ 40F or less and that cooked food reaches a temperature of at least 165F Leftovers that have been reheated poorly can still contain active food pathogens. Moreover, if leftovers have gone bad, no amount of reheating will make them safe. Do not keep leftovers for too long. Any signs of discoloration, sliminess, growth of mold etc. are signals to discard or compost the leftovers. Never reheat leftovers more than once.
