This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.

Most are familiar with the phase, “Sleep tight, don’t let the bed bugs bite,” but few people know what a bed bug looks like or problems they can cause. From World War II until just recently, bed bugs were not at all common in the United States.  Bed bugs are now found in many homes, apartments, college dorm rooms, and even in public facilities such as theaters, hospitals, schools, and libraries.  Now that bed bugs are back, everyone needs to know how to recognize them, how they move from one location to the next, and where they hide so we can prevent large infestations.

This year’s World Rabies Day theme “Together Against Rabies” is appropriate given the number and diversity of organizations around the world focused on preventing the spread of rabies in people, pets, livestock and wildlife.

Since 2007, the Global Alliance for Rabies Control has sponsored World Rabies Day on September 28 to promote rabies awareness and reduce rabies transmission. For its part, the APHIS-Wildlife Services (WS) program has been working cooperatively with local, State, and Federal governments, international partners, universities and others since 1995 to prevent the spread of rabies in wildlife in North America.

Over the past four years, USDA has worked closely with schools, parents, community leaders, and nutrition experts to ensure that when children go off to school, they are greeted by a healthier school environment.  According to the CDC, childhood obesity has more than doubled in children and quadrupled in adolescents in the past 30 years, leading to an increase in obesity-related health outcomes in children, including cardiovascular disease, pre-diabetes, and bone and joint problems.  Improving school nutrition is vital to reducing childhood obesity, because many children consume half of their daily calories during the school day. Making the healthy choice the easy choice sets our nation’s children up for a lifetime of healthy choices, and supports a healthier next generation.  Recently, we’ve seen evidence that student acceptance of healthier meals is increasing across all grade levels.  Today, we are pleased to see the results of the latest poll by The Pew Charitable Trusts, the Robert Wood Johnson Foundation, and the American Heart Association, showing that most parents support the healthier meal and snack standards implemented through the Healthy, Hunger-free Kids Act of 2010.

Read more about the results of that study in this guest blog, from the American Heart Association.

A majority of parents favor strong national nutrition standards for food and drink sold at schools, according to a poll released Monday by The Pew Charitable Trusts, the Robert Wood Johnson Foundation and the American Heart Association.

In addition, the poll found that parents would also like to see salt limited in school foods and more fruits and vegetables served.

Food poisoning is a serious public health threat. CDC estimates that approximately 1 in 6 Americans (or 48 million people) could suffer from food poisoning illness this year, resulting in roughly 128,000 hospitalizations and 3,000 deaths. This September, to celebrate Food Safety Education Month, the U.S. Department of Agriculture (USDA) Food Safety Inspection Service (FSIS) will help get the word out about important safety tips and tools to combat foodborne illness by hosting a free two-part webinar series: “Food Safety 101”. The series will be hosted by FSIS’ Food Safety Education Staff, and will feature speakers from the USDA Meat and Poultry Hotline, FSIS’ Office of Public Health Science, Kansas State University, and the International Food Information Council.

The webinars will emphasize USDA’s four steps to food safety: Clean, Separate, Cook, and Chill and offer a unique opportunity to hear from FSIS’s educators, researchers and partners. “Back to Basics”, the first webinar in this series, will occur on September 10^th from noon to 1:30 pm EST and cover basic food safety tasks and the risks that can be avoided with proper food safety practices. “Everyday Application” will occur a week later on September 17^th from noon to 1:30 pm EST. Participants of the second webinar will be able to identify common kitchen food safety blunders, and alternatives to keep your family foodborne illness free.

Many people are squeezing in the last bit of summer by enjoying the outdoors through walks, hiking on trails, biking, camping, outdoor sports, and picnics in parks and forests.  Unfortunately, these activities – sometimes even in our own backyards – increase our risk of being exposed to ticks and the diseases they carry.

Ticks are a nuisance.  No one wants anything on their body that drinks their blood or – worse than that – also give you a disease.  Most people are familiar with Lyme disease, but not the many other equally serious diseases that ticks carry. The Centers for Disease Control and Prevention (CDC) now lists 14 diseases that ticks in the United States can transmit and cause human disease.  The CDC website also has regional distribution maps with pictures of the ticks that carry these diseases and where in the nation they are most like to be.

You may have heard about the FSIS announcement this week that the Wolverine Packing Company in Detroit, MI was recalling 1.8 million pounds of ground beef products that may be contaminated with E. coli O157:H7.  This recall is linked to 11 patients in four states.  I wanted to provide an update on what FSIS is doing based on the evidence available.

FSIS was notified of the first illness on May 8 and immediately began working with our partners at the Center for Disease Control and Prevention (CDC) to find the source of these illnesses.  Based on the initial findings in the investigations, FSIS and CDC were able to establish a direct link to ground beef products supplied by Wolverine Packing Company.

During the month of April we will take a closer look at USDA’s Groundbreaking Research for a Revitalized Rural America, highlighting ways USDA researchers are improving the lives of Americans in ways you might never imagine.  For example, researching mosquitoes that spread diseases that threaten human health worldwide.

Today is World Health Day, and this year’s theme is vector-borne diseases—those diseases spread by organisms like insects, ticks and snails.  Significant vector-borne diseases in the Americas include dengue fever, malaria, leishmaniasis, lymphatic filariasis and schistosomiasis.

One of the most egregious offenders is the mosquito, and the scientists of USDA’s Agricultural Research Service (ARS) are taking aim at this winged attacker with weapons ranging from traditional remedies to computer modeling and satellite images.

USDA believes in giving children a foundation for life-long health through access to healthy food and quality nutrition education.  So, that’s why we are encouraged by a couple of recent studies that indicate that the rates of obesity among young children are declining.  One study, published in the Journal of the American Medical Association, found that rates of obesity among young children ages 2-5 years have declined in the last decade, while another found that obesity is declining in low-income preschoolers in 19 states.  These results suggest that we are making progress in our efforts to improve the health of our next generation!  These findings were noted by Dr. Bill Dietz, former Director of CDC’s Division of Nutrition, Physical Activity, and Obesity during his presentation at the 3rd meeting of the 2015 Dietary Guidelines Advisory Committee on March 14, 2014.

Efforts to turn the tide of obesity, both within the Federal government and in communities across the country, are having an impact in the preschool population.  The USDA’s Food, Nutrition, and Consumer Services programs are an important part of these efforts.  Through the Healthy Hunger Free Kids Act, USDA is making critical changes to the foods available to children – even the picky eaters.

As National Nutrition Month hits its stride, USDA is excited to announce more evidence that the WIC program is building a healthier future for our nation’s youngest and most vulnerable.  A new USDA study finds that the program continues to serve a high percentage of those who qualify, providing them the nutritional access and resources necessary for a healthy lifestyle.

Officially known as the Special Supplemental Nutrition Program for Women, Infants and Children, WIC offers an important boost to the wellbeing of low-income families. The program provides prescribed, healthy, supplemental foods, as well as nutrition education (including breastfeeding promotion and support), and health care referrals to more than 8.5 million low-income pregnant, postpartum and breastfeeding women, and infants and young children.  The Centers for Disease Control and Prevention (CDC) has identified the WIC program as a key public health force in the nation’s fight against childhood obesity.

This week at USDA, we took several steps forward in the fight for a healthier future for our nation’s children.

On Tuesday, we rolled out new proposed guidelines that will make sure only healthy foods and beverages are allowed to be marketed to kids at school. The new guidelines will ensure that schools remain a safe place where kids can learn and where the school environment promotes healthy choices.
