NJDA Memo – First Theileria orientalis Ikeda Positive Cattle Case in New Jersey

I’ve included for you a memo from the New Jersey Department of Agriculture regarding Theileria orientalis subtype Ikeda found in NJ.

Theileria orientalis Ikeda is a tickborne protozoan infection in cattle (but can impact sheep and goats) that is most commonly spread through the bite of an ixodid tick. An emerging vector for this disease is the Asian longhorned tick (Haemaphysalis longicornis), a tick that was first identified in Hunterdon County in 2017 and has since been detected in 21 states and DC. This tick is active in New Jersey from March through October or early November (Ticks Don’t Take a Winter Vacation).

Well, what will happen if animals get bitten by an infected tick?

  • The T. orientalis Ikeda protozoa will infect the red and white blood cells, which results in anemia in affected animals.
    • Due to anemia, infected cattle may appear similar to those affected by anaplasmosis.
  •  Common clinical signs include weakness, inappetence, pyrexia (elevated body temperature), mucosal pallor (pale gums/mucus membranes), jaundice, and elevated respiratory and heart rates.

T. orientalis Ikeda infections have been reported to cause mortality in 1- 5% of infected cattle but can be as high as 50%. Pregnant heifers and calves are particularly susceptible to infection. While there are several types of T. orientalis found in the United States, to date, only T. orientalis genotype Ikeda has been shown to cause severe illness in animals.

How do you control it?

  • There is no approved treatment or vaccine for T. orientalis in cattle in the United States.
  • The best method of prevention is tick control. Recommended strategies include:
    • Veterinary-approved pesticide treatment (such as pour-on and ear tags)
    • Regular tick inspections
    • Clearing of bushes
    • Keeping pastures and grass mowed short.

A useful document can be found here: Managing the Asian Longhorned Tick: Checklist for Best Management Practices for Cattle Producers

The NJDA Animal Health Diagnostic Laboratory (AHDL) is currently working to coordinate diagnostic testing for T. orientalis. For further information on testing, veterinarians should contact the laboratory at (609) 406-6999 or via email at jerseyvetlab@ag.nj.gov. As an emerging disease in New Jersey, knowing detected cases of T. orientalis can help determine the impact of this disease on New Jersey cattle.

Survey on Corn Earworm Management Practices and Costs in Sweet Corn

If you are a fresh-market grower of sweet corn, the regional Corn Earworm IPM team would like your input! The CEW IPM team includes entomologists and extension specialists across multiple states and institutions, such as the Northeastern and Southeastern IPM Centers and universities in NJ, NY, DE, MD, NC, VA, and GA.

This short survey aims to gather information on your current CEW control practices and their associated costs. This information will be used to evaluate how alternative CEW control practices can affect grower costs, sales, and financial performance. Most importantly, your participation will help us help you; this information will guide future recommendations for more sustainable management practices you can implement on your farms.

Note that this survey is aimed at fresh-market growers; a separate survey will be sent out for those who grow sweet corn for processing.

To take the survey online, please use this link. If you prefer, here is a PDF version of the survey to print and fill out. For more information on the regional CEW team/project, visit CEWIPM.org for the latest updates. Your participation is greatly appreciated!

UPDATE: APHIS Establishes Box Tree Moth (Cydalima perspectalis) Quarantines in Delaware and Pennsylvania

FROM APHIS EMAIL:

Subject:           APHIS Establishes Box Tree Moth (Cydalima perspectalis) Quarantines in Delaware and Pennsylvania

To:                   State, Tribal, and Territory Agricultural Regulatory Officials

Effective immediately, the Animal and Plant Health Inspection Service (APHIS), in cooperation with the Delaware Department of Agriculture and the Pennsylvania Department of Agriculture (PDA), is adding the entire State of Delaware and Erie County, Pennsylvania to the box tree moth (BTM; Cydalima perspectalis) quarantined area.

APHIS is taking this action in response to the confirmed detections of BTM in a residence in Little Creek, Delaware, on July 11 and in Lakeside Cemetery in Erie, Erie County, Pennsylvania, on August 29. PDA has established an intrastate quarantine area for BTM that parallels the Federal quarantine. This Federal Order supersedes Federal Order DA-2024-17.

To prevent the spread of BTM, APHIS considers it necessary to regulate the interstate movement of regulated articles of boxwood from quarantined areas. Boxwood plants may only be moved interstate from a quarantined area from an establishment operating under a compliance agreement, and only if accompanied by a certificate issued by a state agricultural authority certifying that the requirements of this Federal Order and the compliance agreement have been met. These requirements will prevent producers and distributors of boxwood from moving infested plants interstate. State agricultural authorities may prescribe additional safeguards and protocols.

APHIS prohibits movement of all other regulated articles of boxwood, including plant parts, pieces, cuttings, clippings, debris, and any portion of the plant, alive or dead, except for decorative purposes.

The attached Federal Order (click here) and additional information about BTM are located on the APHIS box tree moth webpage. For additional information, you may contact:

Matthew Travis
National Policy Manager

Box Tree Moth poses a serious threat to boxwood production, maintenance, and export.

If you see, or think you see this pest, or its damages in New Jersey please contact:

  • Nursery Inspection Program Manager: Sarah Katzenbach –  sarah.katzenbach@ag.nj.gov  (609) 406-6939

Nationwide Survey on Vectors through Iowa State Center for Food Security and Public Health

The Iowa State University Center for Food Security and Public Health (CFSPH) would like to hear from you and your colleagues! They are requesting participation in a 5-minute survey on vectors (ticks, mosquitoes, mites, and other arthropods of veterinary health concern) where responses will help guide resource creation. This survey is part of a project funded by USDA’s National Animal Disease Preparedness and Response Program (NADPRP).

CFSPH invites responses from anyone over the age of 18 who lives or works with animals (including honey bees). This includes: U.S. veterinary personnel, animal health professionals, farmers/producers, pet owners, and beekeepers.

Access to this survey will close on December 15th, 2024, so there is still time to participate.

If interested, here is the link to access the survey: Survey on Vectors

Webinar: FSMA PSR, Pre-Harvest Water – Wednesday, January 8, 2025, 12 pm – 1 pm

During this one-hour lunchtime webinar, learn the ins and outs of the Food Safety Modernization Act: Produce Safety Rule (FSMA: PSR), Pre-Harvest Water changes. The final rule establishes requirements for systems-based pre-harvest agricultural water inspections and assessments for hazard identification and risk management decision-making on covered farms.

Covered farms – those that are subject to the requirements in the FSMA: PSR – that use pre-harvest agricultural water for covered produce are required to conduct agricultural water inspections and assessments at least once annually, or whenever a significant change occurs that increases the likelihood that a known or reasonably foreseeable hazard will be introduced into or onto produce or food contact surfaces. As part of their pre-harvest agricultural water assessments, farms must evaluate certain factors that could impact produce safety as a result of pre-harvest agricultural water use (e.g., agricultural water use practices, crop characteristics, environmental conditions, etc.).

The deadline to register is Monday, January 6, 2025. To sign up or for more information go to https://onfarmfoodsafety.rutgers.edu/trainings/.
