OSHA, NIOSH issue new hazard alert for crystalline silica exposure

OSHA and the National Institute for Occupational Safety and Health (NIOSH) recently issued a joint hazard alert about protecting workers from significant crystalline silica exposure during manufacturing, finishing, and installing natural and manufactured stone countertops.

The hazard alert follows reports of 46 workers in Spain and 25 workers in Israel who developed silicosis—an incurable, progressively disabling and sometimes fatal lung disease—as a result of exposure to crystalline silica in their work manufacturing stone countertops. Ten of the workers in Israel required lung transplants as a result of their condition.

OSHA and NIOSH have identified exposure to silica as a health hazard to workers involved in stone countertop operations in the United States, both in fabrication shops and during in-home finishing/installation. The alert jointly issued by OSHA and NIOSH explains how this hazard can be mitigated with simple and effective dust controls.

Crystalline silica is found in granite, sandstone, quartzite, various other rocks and sand. Workers who inhale very small crystalline silica particles are at risk for silicosis. Symptoms of silicosis can include shortness of breath, cough and fatigue, and may or may not be obviously attributable to silica. Workers exposed to airborne crystalline silica also are at increased risk for lung cancer, chronic obstructive pulmonary disease and kidney disease.

The hazard alert details what can be done at stone countertop fabrication and installation worksites to protect workers from exposure to silica. This includes monitoring the air to determine silica exposure levels; using engineering controls and safe work practices to control dust exposure; and providing workers with respiratory protection when needed, training, and information about the hazards of silica.

OSHA’s current permissible exposure limit (PEL) for crystalline silica is 100 micrograms per cubic meter of air as an 8-hour time-weighted average (TWA). However, in August 2013, the agency proposed to reduce the exposure limit to an 8-hour TWA of 50 micrograms per cubic meter and create a comprehensive standard for silica exposure including medical surveillance, worker training, and recordkeeping measures. Public hearings on the proposal took place from March 18–April 4, 2014.

The following are some of the engineering and work practice controls to reduce silica exposure recommended in the hazard alert:
  • Use water spraying systems and remote-controlled tools at the impact site where a saw or grinder generates dust.
  • Use hand tools (e.g., drills, masonry saws, grinders) equipped with a shroud and a vacuum with a high efficiency particulate air (HEPA) filter when methods are not practical.
  • Use wet sweeping or HEPA-filtered vacuuming instead of dry sweeping or compressed air.
  • Pre-wash stone slabs prior to cutting.
  • Implement regular and thorough housekeeping procedures for water slurry and settled dust.

Heart-healthy diet: 8 steps to prevent heart disease

Changing your eating habits can be tough. Start with these eight strategies to kick-start your way toward a heart-healthy diet.
Although you might know that eating certain foods can increase your heart disease risk, it's often tough to change your eating habits. Whether you have years of unhealthy eating under your belt or you simply want to fine-tune your diet, here are eight heart-healthy diet tips. Once you know which foods to eat more of and which foods to limit, you'll be on your way toward a heart-healthy diet.

1. Control your portion size

How much you eat is just as important as what you eat. Overloading your plate, taking seconds and eating until you feel stuffed can lead to eating more calories, fat and cholesterol than you should. Portions served in restaurants are often more than anyone needs. Keep track of the number of servings you eat — and use proper serving sizes — to help control your portions. Eating more of low-calorie, nutrient-rich foods, such as fruits and vegetables, and less of high-calorie, high-sodium foods, such as refined, processed or fast foods, can shape up your diet as well as your heart and waistline.
A serving size is a specific amount of food, defined by common measurements such as cups, ounces or pieces. For example, one serving of pasta is 1/2 cup, or about the size of a hockey puck. A serving of meat, fish or chicken is 2 to 3 ounces, or about the size and thickness of a deck of cards. Judging serving size is a learned skill. You may need to use measuring cups and spoons or a scale until you're comfortable with your judgment.

2. Eat more vegetables and fruits

Vegetables and fruits are good sources of vitamins and minerals. Vegetables and fruits are also low in calories and rich in dietary fiber. Vegetables and fruits contain substances found in plants that may help prevent cardiovascular disease. Eating more fruits and vegetables may help you eat less high-fat foods, such as meat, cheese and snack foods.
Featuring vegetables and fruits in your diet can be easy. Keep vegetables washed and cut in your refrigerator for quick snacks. Keep fruit in a bowl in your kitchen so that you'll remember to eat it. Choose recipes that have vegetables or fruits as the main ingredient, such as vegetable stir-fry or fresh fruit mixed into salads.
Fruits and vegetables to chooseFruits and vegetables to avoid
  • Fresh or frozen vegetables and fruits
  • Low-sodium canned vegetables
  • Canned fruit packed in juice or water
  • Coconut
  • Vegetables with creamy sauces
  • Fried or breaded vegetables
  • Canned fruit packed in heavy syrup
  • Frozen fruit with sugar added

3. Select whole grains

Whole grains are good sources of fiber and other nutrients that play a role in regulating blood pressure and heart health. You can increase the amount of whole grains in a heart-healthy diet by making simple substitutions for refined grain products. Or be adventuresome and try a new whole grain, such as whole-grain couscous, quinoa or barley.
Another easy way to add whole grains to your diet is ground flaxseed. Flaxseeds are small brown seeds that are high in fiber and omega-3 fatty acids, which can lower your total blood cholesterol. You can grind the seeds in a coffee grinder or food processor and stir a teaspoon of them into yogurt, applesauce or hot cereal.
Grain products to chooseGrain products to limit or avoid
  • Whole-wheat flour
  • Whole-grain bread, preferably 100% whole-wheat bread or 100% whole-grain bread
  • High-fiber cereal with 5 g or more of fiber in a serving
  • Whole grains such as brown rice, barley and buckwheat (kasha)
  • Whole-grain pasta
  • Oatmeal (steel-cut or regular)
  • Ground flaxseed
  • White, refined flour
  • White bread
  • Muffins
  • Frozen waffles
  • Corn bread
  • Doughnuts
  • Biscuits
  • Quick breads
  • Granola bars
  • Cakes
  • Pies
  • Egg noodles
  • Buttered popcorn
  • High-fat snack crackers

4. Limit unhealthy fats and cholesterol

Limiting how much saturated and trans fats you eat is an important step to reduce your blood cholesterol and lower your risk of coronary artery disease. A high blood cholesterol level can lead to a buildup of plaques in your arteries, called atherosclerosis, which can increase your risk of heart attack and stroke.
The American Heart Association offers these guidelines for how much fat and cholesterol to include in a heart-healthy diet:
Type of fatRecommendation
Saturated fatLess than 7% of your total daily calories, or less than 14 g of saturated fat if you follow a 2,000-calorie-a-day diet
Trans fatLess than 1% of your total daily calories, or less than 2 g of trans fat if you follow a 2,000-calorie-a-day diet
CholesterolLess than 300 mg a day for healthy adults; less than 200 mg a day for adults with high levels of LDL ("bad") cholesterol or those who are taking cholesterol-lowering medication
The best way to reduce saturated and trans fats in your diet is to limit the amount of solid fats — butter, margarine and shortening — you add to food when cooking and serving. You can also reduce the amount of saturated fat in your diet by trimming fat off your meat or choosing lean meats with less than 10 percent fat.
You can also use low-fat substitutions when possible for a heart-healthy diet. For example, top your baked potato with salsa or low-fat yogurt rather than butter, or use low-sugar fruit spread on your toast instead of margarine.
You may also want to check the food labels of some cookies, crackers and chips. Many of these snacks — even those labeled "reduced fat" — may be made with oils containing trans fats. One clue that a food has some trans fat in it is the phrase "partially hydrogenated" in the ingredient list.
When you do use fats, choose monounsaturated fats, such as olive oil or canola oil. Polyunsaturated fats, found in nuts and seeds, also are good choices for a heart-healthy diet. When used in place of saturated fat, monounsaturated and polyunsaturated fats may help lower your total blood cholesterol. But moderation is essential. All types of fat are high in calories.

Fats to chooseFats to limit
  • Olive oil
  • Canola oil
  • Margarine that's free of trans fats
  • Cholesterol-lowering margarine, such as Benecol, Promise Activ or Smart Balance
  • Butter
  • Lard
  • Bacon fat
  • Gravy
  • Cream sauce
  • Nondairy creamers
  • Hydrogenated margarine and shortening
  • Cocoa butter, found in chocolate
  • Coconut, palm, cottonseed and palm-kernel oils

5. Choose low-fat protein sources

Lean meat, poultry and fish, low-fat dairy products, and egg whites or egg substitutes are some of your best sources of protein. But be careful to choose lower fat options, such as skim milk rather than whole milk and skinless chicken breasts rather than fried chicken patties.
Fish is another good alternative to high-fat meats. And certain types of fish are rich in omega-3 fatty acids, which can lower blood fats called triglycerides. You'll find the highest amounts of omega-3 fatty acids in cold-water fish, such as salmon, mackerel and herring. Other sources are flaxseed, walnuts, soybeans and canola oil.
Legumes — beans, peas and lentils — also are good sources of protein and contain less fat and no cholesterol, making them good substitutes for meat. Substituting plant protein for animal protein — for example, a soy or bean burger for a hamburger — will reduce your fat and cholesterol intake.
Proteins to chooseProteins to limit or avoid
  • Low-fat dairy products such as skim or low-fat (1%) milk, yogurt and cheese
  • Egg whites or egg substitutes
  • Fish, especially fatty, cold-water fish, such as salmon
  • Skinless poultry
  • Legumes
  • Soybeans and soy products, for example, soy burgers and tofu
  • Lean ground meats
  • Full-fat milk and other dairy products
  • Organ meats, such as liver
  • Egg yolks
  • Fatty and marbled meats
  • Spareribs
  • Cold cuts
  • Hot dogs and sausages
  • Bacon
  • Fried or breaded meats

6. Reduce the sodium in your food

Eating a lot of sodium can contribute to high blood pressure, a risk factor for cardiovascular disease. Reducing sodium is an important part of a heart-healthy diet. The Department of Agriculture recommends:
  • Healthy adults have no more than 2,300 milligrams (mg) of sodium a day (about a teaspoon)
  • People age 51 or older, African-Americans, and people who have been diagnosed with high blood pressure, diabetes or chronic kidney disease have no more than 1,500 mg of sodium a day
Although reducing the amount of salt you add to food at the table or while cooking is a good first step, much of the salt you eat comes from canned or processed foods, such as soups and frozen dinners. Eating fresh foods and making your own soups and stews can reduce the amount of salt you eat. If you like the convenience of canned soups and prepared meals, look for ones with reduced sodium. Be wary of foods that claim to be lower in sodium because they are seasoned with sea salt instead of regular table salt — sea salt has the same nutritional value as regular salt.
Another way to reduce the amount of salt you eat is to choose your condiments carefully. Many condiments are available in reduced-sodium versions, and salt substitutes can add flavor to your food with less sodium.
Low-salt items to chooseHigh-salt items to avoid
  • Herbs and spices
  • Salt substitutes
  • Reduced-salt canned soups or prepared meals
  • Reduced-salt versions of condiments, such as reduced-salt soy sauce and reduced-salt ketchup
  • Table salt
  • Canned soups and prepared foods, such as frozen dinners
  • Tomato juice
  • Soy sauce

7. Plan ahead: Create daily menus

You know what foods to feature in your heart-healthy diet and which ones to limit. Now it's time to put your plans into action.
Create daily menus using the six strategies listed above. When selecting foods for each meal and snack, emphasize vegetables, fruits and whole grains. Choose lean protein sources and limit high-fat and salty foods. Watch your portion sizes and add variety to your menu choices. For example, if you have grilled salmon one evening, try a black-bean burger the next night. This helps ensure that you'll get all of the nutrients your body needs. Variety also makes your meals and snacks more interesting.

8. Allow yourself an occasional treat

Allow yourself an indulgence every now and then. A candy bar or handful of potato chips won't derail your heart-healthy diet. But don't let it turn into an excuse for giving up on your healthy-eating plan. If overindulgence is the exception, rather than the rule, you'll balance things out over the long term. What's important is that you eat healthy foods most of the time.
Incorporate these eight tips into your life, and you'll continue to find that heart-healthy eating is both doable and enjoyable. With planning and a few simple substitutions, you can eat with your heart in mind.

Food Safety Tips for areas affected by severe weather

The U.S. Department of Agriculture’s (USDA) Food Safety and Inspection Service (FSIS) recommends that consumers take the following steps to reduce food waste and the risk of foodborne illness during severe weather events.
 
Steps to follow if the power goes out:
  • Keep appliance thermometers in both the refrigerator and the freezer to ensure temperatures remain food safe during a power outage. Safe temperatures are 40°F or lower in the refrigerator, 0°F or lower in the freezer.
  • Freeze water in one-quart plastic storage bags or small containers prior to a storm. These containers are small enough to fit around the food in the refrigerator and freezer to help keep food cold. Remember, water expands when it freezes so don’t overfill the containers.
  • Freeze refrigerated items, such as leftovers, milk and fresh meat and poultry that you may not need immediately—this helps keep them at a safe temperature longer.
  • Know where you can get dry ice or block ice.
  • Have coolers on hand to keep refrigerator food cold if the power will be out for more than four hours.
  • Group foods together in the freezer—this ‘igloo’ effect helps the food stay cold longer.
  • Avoid putting food outside in ice or snow, because it attracts wild animals or could thaw when the sun comes out.
  • Keep a few days’ worth of ready-to-eat foods that do not require cooking or cooling.
  • Keep the refrigerator and freezer doors closed as much as possible. A refrigerator will keep food cold for about 4 hours if the door is kept closed. A full freezer will hold its temperature for about 48 hours (24 hours if half-full).
  • Place meat and poultry to one side of the freezer or on a tray to prevent cross contamination of thawing juices.
  • Use dry or block ice to keep the refrigerator as cold as possible during an extended power outage. Fifty pounds of dry ice should keep a fully-stocked 18-cubic-feet freezer cold for two days.
 
Steps to follow after a weather emergency:
  • Check the temperature inside of your refrigerator and freezer. Discard any perishable food (such as meat, poultry, seafood, eggs or leftovers) that has been above 40°F for two hours or more.
  • Check each item separately. Throw out any food that has an unusual odor, color or texture or feels warm to the touch.
  • Check frozen food for ice crystals. The food in your freezer that partially or completely thawed may be safely refrozen if it still contains ice crystals or is 40°F or below.
  • Never taste a food to decide if it’s safe.
  • When in doubt, throw it out.

February is American Heart Month

During the month of February, Americans see the human heart as the symbol of love. February is American Heart Month, a time to show yourself the love. Learn about your risks for heart disease and stroke and stay "heart healthy" for yourself and your loved ones.
Cardiovascular disease (CVD)—including heart disease, stroke, and high blood pressure—is the number 1 killer of women and men in the United States. It is a leading cause of disability, preventing Americans from working and enjoying family activities.1 CVD costs the United States over $300 billion each year, including the cost of health care services, medications, and lost productivity.1

Understanding the Burden of CVD

CVD does not affect all groups of people in the same way. Although the number of preventable deaths has declined in people aged 65 to 74 years, it has remained unchanged in people under age 65. Men are more than twice as likely as women to die from preventable CVD.2
Having a close relative who has heart disease puts you at higher risk for CVD. Health disparities based on geography also exist. During 2007–2009, death rates due to heart disease were the highest in the South and lowest in the West.
Race and ethnicity also affect your risk. Nearly 44% of African American men and 48% of African American women have some form of CVD. And African Americans are more likely than any other racial or ethnic group to have high blood pressure and to develop the condition earlier in life. About 2 in 5 African American adults have high blood pressure, yet fewer than half of them have the condition under control.
Many CVD deaths could have been prevented through healthier habits, healthier living spaces, and better management of conditions like high blood pressure and diabetes.2

Take It One Step at a Time

You can control a number of risk factors for CVD, including:
  • Diet
  • Physical activity
  • Tobacco use
  • Obesity
  • High blood pressure
  • High blood cholesterol
  • Diabetes
As you begin your journey to better heart health that can last a lifetime, keep these things in mind:
  • Try not to become overwhelmed. Every step brings you closer to a healthier heart, and every healthy choice makes a difference!
  • Partner up. The journey is more fun—and often more successful—when you have company. Ask friends and family to join you.
  • Don't get discouraged. You may not be able to take all of the steps at one time. Get a good night's sleep—also important for a healthy heart—and do what you can tomorrow.
  • Reward yourself. Find fun things to do to decrease your stress. Round up some colleagues for a lunchtime walk, join a singing group, or have a healthy dinner with your family or friends.

Plan for Prevention

Try out these strategies for better heart health. You'll be surprised how many of them can become lifelong habits!
Work with your health care team. Get a checkup at least once each year, even if you feel healthy. A doctor, nurse, or other health care professional can check for conditions that put you at risk for CVD, such as high blood pressure and diabetes—conditions that can go unnoticed for too long.
Monitor your blood pressure. High blood pressure often has no symptoms, so be sure to have it checked on a regular basis. You can check your blood pressure at home, at a pharmacy, or at a doctor's office. Find more information at CDC's High Blood Pressure Web site.
Get your cholesterol checked. Your health care team should test your cholesterol levels at least once every 5 years. Talk with your health care professional about this simple blood test. You can find out more from CDC's High Cholesterol Web site.
Eat a healthy diet. Choosing healthful meal and snack options can help you avoid CVD and its complications. Limiting sodium in your diet can lower your blood pressure. Be sure to eat plenty of fresh fruits and vegetables—adults should have at least five servings each day. Eating foods low in saturated fat, trans fat, and cholesterol and high in fiber. For more information on eating a healthy diet, visit CDC's Nutrition page and ChooseMyPlate.gov.
Maintain a healthy weight. Being overweight or obese can increase your risk for CVD. To determine whether your weight is in a healthy range, health care professionals often calculate a number called body mass index (BMI). Doctors sometimes also use waist and hip measurements to measure a person's body fat. If you know your weight and height, you can calculate your BMI at CDC's Assessing Your Weight Web site.
Exercise regularly. Physical activity can help you maintain a healthy weight and lower cholesterol and blood pressure. The Surgeon General recommends that adults should engage in moderate-intensity activity for at least 150 minutes per week. Remember to incorporate exercise into your day in different ways: take the stairs instead of the elevator, or rake the yard instead of using the leaf blower. Exercising with friends and family can be a great way to stay healthy and have fun. For more information, visit CDC's page on physical activity.
Don't smoke. Cigarette smoking greatly increases your risk for CVD. If you don't smoke, don't start. If you do smoke, quit as soon as possible. Your health care team can suggest ways to help you quit. For more information about tobacco use and quitting, see CDC's Smoking & Tobacco Use Web site andSmokefree.gov.
Limit alcohol use. Avoid drinking too much alcohol, which can increase your blood pressure. Men should stick to no more than two drinks per day, and women to no more than one. For more information, visit CDC's Alcohol and Public Health Web site.
Manage your diabetes. If you have diabetes, monitor your blood sugar levels closely, and talk with your health care team about treatment options. VisitCDC's Diabetes Public Health Resource for more information.
Take your medicine. If you're taking medication to treat high blood pressure, high cholesterol, diabetes, or another condition, follow the instructions carefully. Always ask questions if you don't understand something. If you have side effects, talk with your health care team about your options.
