Humans aren't the only ones coming down sick ahead of the holiday season.  

"Just like people get the flu, birds get the flu. Some strains are a lot worse than others. In this case, it's really bad. It kills the birds," said David Anderson, an economist at AgriLife. 

Across the country, avian flu outbreaks are taking a toll on the turkey and chicken industry, leaving farmers scrambling as they try to protect their birds. 

"We started off the year as normal at our normal time with 600 birds. They had not even left the rooting barn yet; the bird flu came into the area," said Cathy Cabalo, the owner of Cabalo's Orchard and Gardens. "When we're looking at 600 turkeys, that are bread and butter to the season, we didn't dare let them outside."

As of November 1, 43 states had at least one confirmed infected flock according to the U.S. Department of Agriculture — with Iowa being one of the hardest hit states in recent weeks. Officials estimate that nearly 48 million birds in the U.S. have been affected so far. 

Out of the 585 flocks confirmed to have cases of Avian flu, 333 are backyard flocks – with the CDC advising folks raising their own birds to do so with caution. That means wearing protective equipment like goggles and masks especially when handling sick or dead birds.

The avian flu is not just an American problem, in the U.K, poultry farmers have been ordered to keep birds indoors as the country has recorded its largest spread on record more than 200 cases. In Japan, 40,000 chickens were ordered slaughtered following positive tests. 

As case numbers rise, businesses are struggling to keep up with holiday demand. 

"Between Avian influenza and high feed costs, right there you have the recipe for higher prices. We see right now at the store, whether wholesale or retail prices," said Anderson. 

Greg Schmidt is the manager of Tower Chicken Farm. 

"My supplier lost over 100,000 birds just in the month of August," said Schmidt. 

Add in inflation and shoppers are feeling the pinch in their wallet. According to Auburn University, turkey prices are 25% higher than they were this time last year — with turkey production estimated to decline 6.4% in 2022. The price of a 15 pound turkey is now nearly $21 compared to $15 last year. 

"Right now we're seeing a little bit of a shortage in the bigger sizes," said Scott Podd, co-owner of Ray's Butcher Shop. 

And if you are looking for a big bird for your Thanksgiving table, industry experts warn that the sooner you purchase or order your holiday bird, the better off you'll be adding that last minute shoppers might find themselves out of "cluck."

Alzheimer’s disease is a complicated condition, and experts are still trying to figure out why some people develop it while others don’t. Now, a new study suggests that what you eat can play a role in your risk of developing Alzheimer’s — and two diets in particular may help lower your chances of developing the devastating disease.The study, which was published in the journal Neurology, examined the brains of more than 580 people who donated their body to Rush University’s Memory and Aging Project, which has been collecting annual dietary information and doing annual check-ups on study participants since 2004. The study analyzed data on the dietary habits of participants from 2014 through 2020 or 2021, and compared that with the number of plaques and tangles that were in each person’s brain during an autopsy.Plaques and tangles, in case you’re not familiar with them, are key markers of Alzheimer’s disease. In a person who has Alzheimer’s disease, beta-amyloid proteins clump together to form plaques that collect between neurons and interfere with cell function, according to the National Institute on Aging (NIA). Tangles are an accumulation of a protein called tau that collect inside neurons and interfere with communication between neurons, the NIA says.The researchers discovered that people who had eating patterns that closely followed the MIND or Mediterranean diets had almost 40% lower chances of developing Alzheimer’s disease than others.The researchers specifically found that green leafy vegetables were the most beneficial, with brain tissue from people who ate the most leafy greens looking nearly 19 years younger in terms of plaque buildup than those who only had one or less servings of leafy greens a week.The study raises a lot of questions about diet’s role in Alzheimer’s disease, as well as why these eating plans in particular may be helpful in lowering your risk. Here’s the deal.How can diet impact a person’s Alzheimer’s risk?There are a lot of potential factors that can influence your risk of developing Alzheimer’s disease, including genetics and aging, the NIA says. As for diet, the National Institutes of Health (NIH) says that it’s possible that what you eat may influence your risk of developing Alzheimer’s disease. The NIH also points to the MIND and Mediterranean diets as being especially helpful in the prevention of Alzheimer’s disease.“We and others previously found that healthy diets are associated with reduced dementia risk and better cognitive function in an aging population,” says lead study author Puja Agarwal, Ph.D., an assistant professor of internal medicine at the Rush University Medical Center in Chicago. What the latest study shows is that diet may be directly related to the formation of plaques and tangles in the brain, Agarwal says.“The exact mechanism of how diet and plaques and tangles relate needs further investigation and we speculated that there might be other mechanisms through which diet may impact the risk for Alzheimer’s disease,” she says.And, at a basic level, you are what you eat, says Amit Sachdev, M.D., M.S., medical director in the Department of Neurology at Michigan State University. “Diet is a metric for overall wellness,” he says. “In general. healthy body means healthy brain.”Why might the MIND and Mediterranean diets lower your risk of developing Alzheimer’s?Again, this is still being explored. However, there are some theories.“One of the proposed mechanisms is that both the MIND and the Mediterranean are plant-based diets rich in various essential nutrients and bioactive compounds that are required to maintain brain health,” Agarwal says. “They also have antioxidant and anti-inflammatory properties which may help prevent amyloid burden and neuronal loss.”Dr. Sachdev agrees that the diets’ anti-inflammatory properties may play a role. “Some diets are better at controlling body-wide inflammation,” he says. “Unfortunately, the typical starch-heavy American diet is not a great choice.” However, he says, the Mediterranean and MIND diets “balance styles of food and portion size in a way that reduces overall burden of body inflammation.”Dr. Sachdev also notes that the Mediterranean diet in particular is linked to blood vessel health. “When we think of Mediterranean diet, we think of the health of blood vessels in the brain and reducing strokes. There is strong evidence for this,” he says. Research has also found that blood vessel issues are linked to an increased risk of Alzheimer’s.Mediterranean diet basicsThe Mediterranean diet is based on the lifestyles of people who live in the Mediterranean region, which includes Greece, Italy, and Spain, explains Jessica Cording, R.D., author of The Little Book of Game-Changers. It focuses on high intakes of vegetables, legumes, fruits, nuts, grains, fish, seafood, extra virgin olive oil, and some red wine. The diet also encourages followers to limit red meat, Cording says.“The Mediterranean diet is designed to be a lifestyle,” Cording says, noting that people on the diet are also encouraged to be active. Research has linked the Mediterranean diet with good heart health, optimal blood sugar levels, and a lowered risk of dementia.MIND diet basicsThe MIND diet (which stands for Mediterranean–DASH Intervention for Neurodegenerative Delay) is a form of the Mediterranean diet that focuses on plant-based foods linked to dementia prevention, according to the NIA. It specifically encourages people to eat from these food groups:Leafy green vegetables, at least six servings/weekOther vegetables, at least one serving/dayBerries, at least two servings/weekWhole grains, at least three servings/dayFish, one serving/weekPoultry, two servings/weekBeans, three servings/weekNuts, five servings/weekWine, one glass/dayOlive oil

U.S. poultry producers are increasing safety measures with flocks as the Centers for Disease Control and Prevention monitor a "highly pathogenic" strain of bird flu which has already been detected in a turkey flock in Indiana, the U.S. Department of Agriculture warned on Wednesday.

As Reuters reported, disease experts are warning the public that wild birds are likely the cause of the bird flu spread which is said to be a highly lethal form of avian flu spreading across the country.

On Feb. 9 the CDC released a statement that said while the health agency believes the risk to the public is low, the statement said, "Outbreaks in domestic poultry, in addition to infections in wild birds, may result in increased exposures in some groups of people, particularly poultry workers, for example."

The USDA said in a statement, "Avian influenza does not present an immediate public health concern. No human cases of these avian influenza viruses have been detected in the United States. As a reminder, the proper handling and cooking of poultry and eggs to an internal temperature of 165 ˚F kills bacteria and viruses."

On Monday Feb. 7, an Indiana farmer discovered around 100 dead turkeys on his farm and saw surviving turkeys appearing to be sick, according to the Indy Star, which reported that almost 30,000 turkeys had to be killed to contain the spread of the virus.
