In case you were wondering, the Food and Drug Administration (FDA) wants you to know that it ensures foods from animals are safe.

If you eat meat or drink milk, you want to know: Are there trace amounts of the veterinary drugs used in food-producing animals entering your diet? And if they are, are the amounts safe for human consumption?

Those questions—among others—are the concern of the Division of Residue Chemistry, which is part of FDA’s Center for Veterinary Medicine.

Sick food-producing animals such as pigs, cows, and chickens can be given antibiotics or other drugs to treat diseases. (Some farms also give animals antibiotics to help them grow faster, a practice FDA is working to eliminate by promoting the judicious use of antimicrobials in food-producing animals.) Producers must then wait for the drug to leave the animal’s system before they can slaughter it for consumption. It’s important to ensure that any remaining trace amounts of the drugs are safe to eat by the time the food reaches our plates.

“Our job is twofold,” says Division Director Philip Kijak, Ph.D. “We validate the methods drug companies use to test for drug trace amounts in foods from animals, and we help develop newer and better methods for testing.”

On the first point, the sponsor—usually, the animal pharmaceuticals company—of a drug to be used in a food animal must complete required testing that establishes the drug’s tolerance (a measure of safety), and develop a method to show whether the trace amount in the animal food product is within that tolerance.

“Then we are responsible for validating that method—making sure not only that it works and is accurate, but that it’s a practical method any standard chemical laboratory can use,” Kijak says.

Making Sure Milk Is Safe

For example, the Division examines the methods used to test milk for trace amounts of veterinary drugs used in dairy cows.

Under the Grade “A” Pasteurized Milk Ordinance standards issued by the FDA and the U.S. Public Health Service, all milk must be tested for beta-lactam antibiotics, the most common drugs used by dairy farms. FDA’s role is to evaluate and approve the data and methods submitted by companies that manufacture rapid-screening tests for these drugs. Rapid screening is important because milk is perishable, and results are needed on the spot.

“Think of these as off-the-shelf kits, like those consumers buy for pregnancy testing,” Kijak says. It’s up to the individual dairies and state regulators to choose the approved kits they want to use. Since 1994, when FDA began evaluating test-kits, the amount of milk containing beta-lactam drugs has dropped from 0.15 percent to 0.014 percent—more than a tenfold decrease, Kijak adds.

Developing Methods to Test Meat

In addition, FDA works with the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) and state regulators to monitor meat, poultry, eggs, and milk for trace amounts of unapproved or unsafe drugs. FSIS tests the foods for a variety of these medications and reports violations to FDA, which follows up with regulatory action when needed.

“To do this job, we had to focus on developing new methods to detect trace amounts of penicillin and other antibiotics,” Kijak says. “With the older method, we were able to tell if penicillin or penicillin and other drugs were present, but we were unable to measure the exact amount of the penicillin when the sample contained more than one drug.” Without this specific information, it was possible for products with unsafe amounts of penicillin to pass inspection. The newer method, which was developed in close cooperation with USDA, enables inspectors to determine if multiple drugs are present, and the amount of each.

Testing for Fungus in Animal Feeds

Recently, the division has become increasingly involved in developing methods to detect mycotoxins and other contaminants in animal feeds. Mycotoxins are toxic compounds made by fungi that grow on grains. Poor growing methods and improper storage conditions can promote the development of these compounds, which that can enter our diets in meat from animals that consumed the contaminated feed.

“While these fungi are almost always present in grain, it’s the amount of mycotoxins that can make the difference between safe and unsafe foods from animals,” Kijak explains. “The new methods enable us to take whatever steps are necessary to make sure the tested products are safe for consumers.”

Busy moms are often operating in a sleep deprivation mode.

So, on those occasions when they have trouble getting to sleep and staying asleep they chalk it up to stress, a sick child or working long hours. But it could be something more than that; it could be a sleep problem or a sleep disorder.

Most adults need at least eight hours of sleep every night to be well rested. Not everyone gets the sleep they need.

About 40 million people in the U.S. suffer from sleep problems every year. Not getting enough sleep for a long time can cause health problems.

Many of us suffer from insomnia which includes:

• Trouble falling asleep

• Having trouble getting back to sleep

• Waking up too early

Insomnia is called chronic when it lasts most nights for a few weeks or more. When this happens it may be time to see your doctor.

The Food and Drug Administration (FDA) offers the following tips for better sleep:

• Go to bed and get up at the same times each day.

• Avoid caffeine, nicotine, beer, wine, and liquor four to six hours before bedtime.

• Don’t exercise within two hours of bedtime.

• Don’t eat large meals within two hours of bedtime.

• Don’t nap later than 3 p.m.

• Sleep in a dark, quiet room that isn’t too hot or cold for you.

• If you can’t fall asleep within 20 minutes, get up and do something quiet.

• Wind down in the 30 minutes before bedtime by doing something relaxing.

 How long should it take to fall asleep? It is normal to take between 10 and 20 minutes to fall asleep. People who fall asleep in less than five minutes may have a serious sleep disorder.

 Feeling sleepy during the day

According to the FDA, feeling tired every now and then is normal. It is not normal for sleepiness to interfere with your daily life. Watch for signs like:

• Slowed thinking • Feeling cranky

• Trouble paying attention

• Heavy eyelids

Several sleep disorders can make you sleepy during the day. One of these is narcolepsy. People with narcolepsy feel very sleepy even after a full night’s sleep.

 Snoring

Snoring is noisy breathing during sleep. It is caused by vibrating in the throat. Some people can make changes that will stop snoring. These include:

• Losing weight

• Cutting down on smoking and alcohol

• Sleeping on your side instead of on your back

 The Centers for Disease Control (CDC) recommends that everyone 6 months of age and older get a seasonal flu vaccine.

The CDC states that children should be vaccinated every flu season for the best protection against flu. For children who will need two doses of flu vaccine, the first dose should be given as early in the season as possible. For other children, it is good practice to get them vaccinated soon after flu vaccine becomes available, ideally by October. However, getting vaccinated even later can be protective, as long as flu viruses are circulating.

While seasonal influenza outbreaks can happen as early as October, most of the time influenza activity peaks in January or later. Since it takes about two weeks after vaccination for antibodies to develop in the body that protect against influenza virus infection, it is best that people get vaccinated so they are protected before influenza begins spreading in their community.

The CDC warns that Influenza (“the flu”) is more dangerous than the common cold for children. Each year, many children get sick with seasonal influenza; some of those illnesses result in death.

• Children commonly need medical care because of influenza, especially before they turn 5 years old.
• Severe influenza complications are most common in children younger than 2 years old.
• Children with chronic health problems like asthma, diabetes and disorders of the brain or nervous system are at especially high risk of developing serious flu complications.
• Each year an average of 20,000 children under the age of 5 are hospitalized because of influenza complications.
• Flu seasons vary in severity, however some children die from flu each year. During the 2013-2014 influenza season, more than 100 flu-related pediatric deaths were reported..

The vaccination is especially important for certain people who are high risk or who are in close contact with high risk persons. This includes those at high risk for developing complications from the flu and adults who are close contacts of those children.

Starting in 2014-2015, CDC recommends use of the nasal spray vaccine (LAIV) for healthy* children 2 through 8 years of age, when it is immediately available and if the child has no contraindications or precautions to that vaccine. Recent studies suggest that the nasal spray flu vaccine may work better than the flu shot in younger children. However, if the nasal spray vaccine is not immediately available and the flu shot is, children 2 years through 8 years old should get the flu shot. Don’t delay vaccination to find the nasal spray flu vaccine. For more information about the new CDC recommendation, see Nasal Spray Flu Vaccine in Children 2 through 8 Years Old

The Dept of Health and Human Services ran an article on HHS.gov about backpacks.This is what they want you to know about children and adults using backpacks.

Backpacks are a better option than shoulder or messenger bags for carrying books and supplies because the weight of the pack is evenly distributed across your body. However, backpacks that are overloaded or not used properly can make for health problems.

How Can Backpacks Cause Problems?

People who carry heavy backpacks sometimes lean forward. Over time, this can cause the shoulders to become rounded and the upper back to become curved. Because of the heavy weight, there’s a chance of developing shoulder, neck, and back pain.

If you wear your backpack over just one shoulder, or carry your books in a messenger bag, you may end up leaning to one side to offset the extra weight. You might develop lower and upper back pain and strain your shoulders and neck.

Not using a backpack properly can lead to poor posture.

Carrying a heavy pack increases the risk of falling, particularly on stairs or other places where the backpack puts the wearer off balance.

People who carry large packs often aren’t aware of how much space the packs take up and can hit others with their packs when turning around or moving through tight spaces, such as the aisles of the school bus. Students also are injured when they trip over large packs or the packs fall on them.

How Do You Know If a Backpack Is a Problem?

You may need to put less in your pack or carry it differently if:

• you have to struggle to get your backpack on or off
• you have to lean forward to carry your pack
• you have back pain

If you adjust the weight or the way you carry your pack but still have back pain or numbness or weakness in your arms or legs, talk to your doctor.

Tips for Choosing and Using Backpacks

• Consider the construction. Before you grab that new bag off the rack, make sure it’s got two padded straps that go over your shoulders. The wider the straps, the better. A backpack with a metal frame like the ones hikers use may give you more support (although many lockers aren’t big enough to hold this kind of pack).
• Carry it well. Before you load your backpack, adjust the straps so the pack sits close to your back. If the pack bumps against your lower back or your butt when you walk, the straps are probably too long. Always pack your backpack with the heaviest items closest to your back. Don’t drop all your stuff in the main compartment (using the side pockets will distribute the weight more evenly).
• Try a pack with wheels. Lots of kids use these as an alternative to backpacks, but there are guidelines and considerations to keep in mind with this kind of pack, too. Many schools don’t allow rolling packs because people can trip over them in the halls.
• Limit your load. Doctors and physical therapists recommend that people carry no more than 10% to 15% of their body weight in their packs. This means that if you weigh 120 pounds, your backpack should weigh no more than 12 to 18 pounds. Choosing a lightweight backpack can get you off to a good start. Use your bathroom scale to weigh your backpack and get an idea of what the proper weight for you feels like.
• Pick it up properly. As with any heavy weight, you should bend at the knees when lifting a backpack to your shoulders.

 The September 2014 edition of the Centers for Disease Control (CDC) Vital Signs focuses on the amount of sodium in children’s diets.

Reducing Sodium in Children’s Diets

Nearly 9 in 10 US children eat more sodium than recommended, and about 1 in 6 children has raised blood pressure, which is a major risk factor for heart disease and stroke. Lowering sodium in children’s diets today can help prevent heart disease tomorrow. Small changes make a big impact on your child’s daily sodium intake. Learn more in the current CDC Vital Signs.

Sources of Sodium

Americans get most of their daily sodium—more than 75%—from processed and restaurant foods.² What is processed food?

Sodium is already in processed and restaurant foods when you purchase them, which makes it difficult to reduce daily sodium intake on your own. Although it is wise to limit your use of added table salt while cooking and at the table, only a small amount of the sodium we consume each day comes from the salt shaker.

Dietary Guidelines for Sodium and Potassium

The Dietary Guidelines for Americans, 2010[PDF-2.9M] recommend that everyone age 2 and up should consume less than 2,300 milligrams (mg) of sodium each day. Some groups of people should further limit sodium intake to 1,500 mg per day, including:

• Adults age 51 or older.
• All African Americans.
• Anyone who has high blood pressure, diabetes, or chronic kidney disease.

Those groups add up to about half of the U.S. population and the majority of adults.

The Dietary Guidelines for Americans also recommend meeting the potassium recommendation (4,700 mg per day). Higher potassium intake can help lower blood pressure. Foods that are high in potassium and low in sodium include bananas, potatoes, yogurt, and dry beans, among others. The U.S. Department of Agriculture’s Sodium and Potassium fact sheet[PDF-153K] has more information about the role of potassium in a healthy diet and a list of foods rich in potassium.

Nearly everyone benefits from lower sodium intake. Learn more about sodium in your diet in Where’s the Sodium?, a February 2012 report from CDC Vital Signs.
