Avian flu confirmed in Tennessee Tyson breeder flock

By Alec Gerry | March 7, 2017

U.S. Department of Agriculture (USDA) officials and Tyson Foods Inc. confirmed avian influenza in a breeder flock in Lincoln County, Tennessee.

On March 5, state and national veterinary authorities announced the appearance of H7 highly pathogenic avian influenza (HPAI) of wild bird lineage on the Tyson contract farm. The USDA’s Animal and Plant Health and Information Service (USDA APHIS) said the flock of 73,500 were culled to prevent spreading the disease.

A March 6 notification published by the World Organisation for Animal Health (OIE) said the incident began on March 1, was reported March 3 and confirmed on March 4. The report said 700 of the broiler breeder flock died of the disease. Depopulation is complete and and a comprehensive epidemiological investigation in the area, along with enhanced surveillance and testing, are underway. State health officials quarantined the site and implemented movement controls.

APHIS said the flock is located in the Mississippi flyway, a migratory bird pattern that crosses Alabama, Arkansas, Indiana, Iowa, Kentucky, Louisiana, Michigan, Minnesota, Mississippi, Missouri, North Dakota, Tennessee, South Dakota and Wisconsin, as well as parts of neighboring states. Avian influenza, absent in U.S. commercial poultry since 2016, was confirmed in a wild bird in Montana in January.

In a press release, Tyson, the U.S.’s largest broiler producer, said it’s responding aggressively to prevent the spread of the disease.

“All flocks located within a six-mile radius of the farm will be tested and will not be transported unless they test negative for the virus,” the company said in a statement. “Based on the limited scope known to us at this time, we don’t expect disruptions to our chicken business and plan to meet our customers’ needs.”

Proposition 2 again being challenged by other states

By Alec Gerry | February 22, 2017

Watt AgNet

The State of Missouri is appealing to the the U.S. Supreme Court to hear a challenge to California’s Proposition 2 law, which took effect in 2015.

Missouri Attorney General Josh Hawley, in a press release, stated that he has asked the high court to hear arguments in the state’s challenge to the California law, which requires that eggs produced and sold in the state are laid by hens that have adequate room to stand up, sit down, turn around and extend their limbs without touching another bird or the sides of the cage. Hawley said the law imposes onerous new regulations on Missouri poultry farmers and would drive up the cost of eggs for Missouri consumers.

“These regulations are unconstitutional,” Hawley said. “They will cost Missouri farmers tens of millions of dollars. They will cost Missouri families. And they will cost our state jobs.”

Alabama, Iowa, Kentucky, Nebraska and Oklahoma are joining Hawley’s appeal.

Missouri Farm Bureau President Blake Hurst stated that his organization is supportive of Hawley’s case.

“This is a vital issue for Missouri farmers,” Hurst said. “If other states can tell Missouri how to farm, we will be in a world of hurt. I applaud the attorney general for standing up for Missouri’s farm families all the way to the United States Supreme Court.

Cattle Fever Tick Quarantine Areas

By Alec Gerry | February 21, 2017

Cattle Fever Ticks, known scientifically as Rhipicephalus (formerly Boophilus) annulatus and R. microplus, are a significant threat to the United States cattle industry. These ticks are capable of carrying the protozoa, or microscopic parasits, Babesia bovis or B. bigemina, commonly known as cattle fever. The Babesia organism attacks and destroys red blood cells, causing acute anemia, high fever, and enlargement of the spleen and liver, ultimately resulting in death for up to 90 percent of susceptible naive cattle.

For more information or questions about the Fever Tick Program, please contact your local TAHC Region Office.

Cattle Fever Tick Quarantine Areas

Their are three types of Fever Tick Quarantine Areas; The Permanent Fever Tick Quarantine “Buffer” Zone, a Control Purpose Quarantine Area, and a Temporary Preventative Quarantine Area. To learn more about the types of Fever Tick Quarantine Zones and Areas, please visit our Fever Tick Frequently Asked Questions Brochure.

Mosquito Repellents: DEET and PMD Sprays Most Effective, While Wearable Devices Disappoint, Study Finds

By Alec Gerry | February 17, 2017

entomology today

A search for “mosquito repellent” on Amazon.com delivers more than 28,000 product results. For a regular consumer, it can be difficult to find the ones that truly work among a sea of products that make bold claims.

Researchers at the Molecular Vector Physiology Laboratory at New Mexico State University are working to make the search for the best mosquito repellents a little easier. And their latest study offers some clear guidance: Spray-on repellents containing DEET or PMD (oil of lemon eucalyptus) are the way to go. Several “wearable” devices such as bracelets and sonic repellers, as well as a candle, were all found to be quite ineffective compared to the sprays. Their study is published online this week in the Journal of Insect Science.

“These findings are extremely important for consumers because they need to be aware that there are mosquito repellent products available that are ineffective,” says Stacy Rodriguez, laboratory manager at the Molecular Vector Physiology Laboratory at NMSU. “While the labels of many products make strong claims, some products simply don’t work.”

Averting Risks to the Food Chain – Ag Abroad

By Alec Gerry | February 2, 2017

Morning Ag Clips

Food availability and food hygiene are compromised every day by diseases and pests that plague plants and animals as well as various types of contaminants. This happens on farms, in factories, at home, in fresh or sea water, in the open air and in the midst of dense forests.

Whether in the form of pathogen, insect or contaminant, threats are now traveling faster and further, making effective and timely responses more difficult and putting people’s food supplies, their health and livelihoods, and often their lives at greater risk.

Every year 1 person in 10 falls ill from eating contaminated food, and it is estimated that around 420 000 people die as a result. Over 70 percent of new diseases of humans have animal origin, with the potential of becoming major public health threats. A third of global crop production is lost annually due to insects and plant diseases that can spread to multiple countries and through continents.

A number of trends are contributing to this, including certain types of intensive farming, deforestation, overgrazing and climate change. In addition, conflicts, civil unrest and globalized trade are all also increasing the likelihood of threats emerging, passing to other countries and becoming devastating in these newly infected countries. Food can be contaminated in the processing and marketing phases – processes that often take place in different countries making it more difficult to identify the point of contamination.

To address the rising number of transboundary animal and plant pests and diseases, FAO has published “Averting risks to the food chain“, a set of proven emergency prevention methods and tools.  They show how prevention, early warning, preparedness, good food chain crisis management and good practices can improve food security and safety, save lives and livelihoods.

The Potential Role of Direct and Indirect Contacts on Infection Spread in Dairy Farm Networks

By Alec Gerry | January 30, 2017


Researchers have shown that looking at movements of operators and vehicles between farms in the same way we look at contacts in social networks can help explain the spread of dangerous infectious diseases of livestock, such as foot-and-mouth disease and avian influenza. This research, published in PLOS Computational Biology, can contribute to the development of more accurate tools for predicting the spread of livestock diseases and may help implement more effective biosecurity measures in farms.

The study, produced by Dr Gianluigi Rossi from the Istituto Zooprofilattico Sperimentale della Lombardia e dell’Emilia Romagna and colleagues, have shown that the network of contacts originated from on-farm visits by veterinarians in dairy farms of Northern Italy displays hidden features that cannot be detected by simply looking at the frequency of visits and unveils patterns of infection otherwise unexplained. The authors discovered that veterinarians’ movements produce an unexpectedly large number of potentially infectious contacts between farms that can quickly spread dangerous livestock diseases.

Death of Dr. Dick Axtell – Veterinary Entomologist at NC State

By Alec Gerry | January 26, 2017

It is with great sorrow that I notify you of the death of Dr. Dick Axtell.
The obituary has not yet been published, but the funeral is scheduled for Saturday (January 28th) afternoon in Raleigh. Dick was the 1993 recipient of the Lifetime Achievement Award in Veterinary Entomology at the Livestock Insect Workers Conference in Santa Fe, NM, and a longtime leader of the LIWC and veterinary entomology in general. Most of our veterinary entomologists can trace their roots back to Dick Axtell, and his impact on the discipline cannot be overestimated.  Dr. Axtell was a longtime and very active member of SOVE.
Our condolences go out to all of his family and friends.
Nancy Hinkle
