Livestock Disease Reporting in Iowa: Rules Every Producer and Veterinarian Must Know

Iowa ranks among the top agricultural states in the nation, with millions of hogs, cattle, poultry, and sheep depending on a disease surveillance system that only works when every participant does their part. When a reportable disease goes undetected or unreported, it can spread across herds, counties, and state lines before anyone has a chance to respond.

Whether you are a livestock producer, a licensed veterinarian, or someone who simply works around animals, understanding your legal obligations under Iowa’s livestock disease reporting framework is not optional — it is the law. This guide breaks down exactly which diseases must be reported, who is responsible for reporting them, how to do it, and what consequences follow if you fail to act.

Reportable Livestock Diseases in Iowa

Iowa’s livestock disease reporting system is built around a defined list of infectious and contagious conditions that pose a serious threat to animal health, agricultural productivity, and in some cases, public health. The list of reportable animal diseases in Iowa is found in Chapter 64: Infectious and Contagious Diseases of the Iowa Administrative Code, administered by the Iowa Department of Agriculture and Land Stewardship (IDALS).

Within the United States and throughout the world, there are diseases that can make food animals sick, causing production losses or even death. Some of these diseases are naturally found in the U.S. and are called endemic diseases, while others are not normally found in the U.S. and are called foreign animal diseases.

Iowa’s reportable disease list covers both categories and spans multiple species. Key diseases that producers and veterinarians must be aware of include:

• Foot-and-mouth disease
• Classical swine fever (hog cholera)
• African swine fever
• Highly Pathogenic Avian Influenza (HPAI)
• Newcastle disease
• Bovine tuberculosis
• Brucellosis
• Vesicular stomatitis
• Scrapie
• Chronic wasting disease (CWD) in cervids
• Anthrax
• Pseudorabies
• Johne’s disease
• Trichomoniasis (in cattle)

The complete list of what the USDA’s Animal and Plant Health Inspection Service (APHIS) considers foreign to the U.S. can be found on the APHIS Notifiable Diseases and Conditions webpage. Iowa’s state list incorporates these federal designations and adds additional diseases of concern to Iowa’s specific livestock industries.

Iowa is a leading pork-producing state, so diseases like African swine fever and classical swine fever receive particular attention. Both IDALS and USDA classify avian influenza as a reportable animal disease, and given Iowa’s massive poultry industry, HPAI is treated with special urgency. You can also learn more about bovine diseases that may trigger reporting obligations and about Newcastle disease, another condition on Iowa’s reportable list.

Who Is Required to Report a Livestock Disease in Iowa

One of the most important aspects of Iowa’s livestock disease reporting framework is how broadly the obligation to report is defined. This is not a duty that falls solely on veterinarians.

Anyone — veterinarians, producers, animal owners, and others — who is suspicious of a reportable animal disease is required to report it to a Federal or State Animal Health Official. This means that if you manage a herd, work on a farm, or have any reason to suspect a reportable condition in an animal, the legal duty to report applies to you personally.

The diagnosis or suspected diagnosis of any listed disease in animals must be reported promptly to the Iowa Department of Agriculture and Land Stewardship by the veterinarian making the diagnosis or suspected diagnosis. Veterinarians carry a specific professional obligation on top of the general duty that applies to everyone else.

Additional parties with reporting responsibilities include:

• Livestock producers and farm operators who observe clinical signs in their animals
• Accredited veterinarians who diagnose or suspect a reportable condition during an examination
• Livestock market operators and inspectors who observe sick animals at sale facilities
• Laboratory directors at diagnostic labs who identify a reportable pathogen in a submitted sample
• Township trustees and local health boards, who under Iowa Administrative Code 64.3 must immediately notify the chief of the division of animal industry when they receive notice of a suspected contagious disease in animals

Anyone within Iowa who knows of a bird with avian influenza, who was exposed to AI, or who is displaying clinical signs of AI is legally required to promptly report it to the State Veterinarian. This same standard of immediate, obligation-based reporting applies across all species and all listed diseases.

Producers dealing with zoonotic diseases — those that can spread from animals to humans — carry an especially significant public health responsibility when reporting. Iowa’s reporting system is also coordinated with federal oversight: during a foreign animal disease response, IDALS collaborates with other partners including but not limited to the Iowa Department of Natural Resources (DNR) and the United States Department of Agriculture (USDA).

Signs and Symptoms That Trigger a Report in Iowa

Because Iowa law requires reporting based on suspicion rather than confirmed diagnosis, knowing which clinical signs should raise a red flag is essential for every producer and caretaker. A sick animal displaying any of the following signs raises the suspicion of a reportable animal disease and should be reported immediately.

Watch for these warning signs across your livestock:

• Sudden, unexplained death — especially multiple animals in a short time period
• Blisters, ulcers, or erosions on the mouth, tongue, feet, or teats
• Severe lameness or reluctance to bear weight
• Excessive salivation or drooling
• Difficulty breathing, labored respiration, or nasal discharge
• Sudden and severe drop in milk production
• Neurological signs such as tremors, circling, or loss of coordination
• Rapid spread of illness through a herd or flock
• Unusual skin lesions, vesicles, or pustules
• High fever accompanied by other systemic signs

For poultry specifically, chickens and turkeys with Low Pathogenic Avian Influenza (LPAI) may show mild signs such as sneezing, coughing, and discharge from their eyes or beak, while those with Highly Pathogenic Avian Influenza (HPAI) may have difficulty breathing or die suddenly.

An animal is also considered “exposed” — and that exposure must be reported — under specific circumstances. An animal must be considered as “exposed” when it has stood in a stable with, or been in contact with, any animal known to be affected with a contagious, infectious, or transmissible disease, or if placed in a stable, yard, or other enclosure where such diseased animals have been kept unless such enclosure has been thoroughly cleaned and disinfected.

Iowa dairy farmers are specifically recommended to report any unusual symptoms in cattle to IDALS at 515-281-5305. This guidance applies broadly — when in doubt about whether a symptom qualifies, make the call. Animal health officials would rather investigate a false alarm than miss a genuine outbreak.

How to Report a Livestock Disease in Iowa

Iowa provides multiple pathways for submitting a livestock disease report, and the process is designed to be accessible around the clock given the urgent nature of potential outbreaks.

Anyone — veterinarians, producers, animal owners, and others — who is suspicious of a reportable animal disease is required to report it to a Federal Animal Health Official at 866-536-7593 or a State Animal Health Official at 515-281-5305.

Here is a step-by-step overview of the reporting process:

1. Isolate the affected animals immediately. Separate sick or suspected animals from the rest of your herd or flock to reduce the risk of spread while you prepare to report.
2. Document what you are seeing. Note the number of animals affected, species, age, clinical signs, onset date, and any recent movements or new animals introduced to the premises.
3. Call the appropriate hotline. Contact the Iowa State Animal Health Official at 515-281-5305 or the federal USDA APHIS hotline at 866-536-7593. Both lines connect you with animal health officials who can guide next steps.
4. Submit a written report when directed. It is the duty of any person who becomes aware of any infectious or contagious disease to report the same in writing to the State Veterinarian, Bureau of Animal Industry, Wallace State Office Building, Des Moines, Iowa 50319, who shall then take such action as deemed necessary for the suppression and prevention of such disease.
5. Cooperate with the investigation. Be prepared to provide access to your premises and records. During a foreign animal disease outbreak, IDALS will conduct epidemiological investigations examining any movement that could have potentially carried disease onto or off a livestock or poultry facility during a minimum of the previous 30 days.

The Iowa State Veterinary Diagnostic Laboratory (ISU VDL) at Iowa State University is a key partner in the confirmation process. After you make your initial report, officials may direct you to submit samples to the ISU VDL for laboratory testing. You can also reach the USDA APHIS Veterinary Services Iowa Area Office at 515-284-4140 for additional guidance.

For producers dealing with avian influenza specifically, anyone who suspects that birds under their care have AI should immediately contact a Federal or State Animal Health Official. Iowa also has a separate permit process for poultry movement from AI-affected states that is coordinated through the Iowa Poultry Association.

Producers in neighboring states can review how reporting works across the region by reading about livestock disease reporting in Illinois and livestock disease reporting in Michigan, which share many parallels with Iowa’s framework.

Reporting Deadlines and Timeframes in Iowa

Iowa’s livestock disease reporting rules emphasize speed above all else. The language used throughout Chapter 64 and across IDALS guidance consistently uses the word “promptly” and in many cases “immediately” — terms that reflect the urgency required when a contagious disease is suspected.

Failure to immediately report to State or Federal officials all diagnosed or suspected cases of foreign animal diseases such as classical swine fever, foot-and-mouth disease, vesicular stomatitis, rinderpest, African swine fever, avian influenza, and Newcastle disease of poultry is treated as a serious regulatory violation.

For brucellosis testing and quarantine situations, specific timelines also apply. Quarantine remains in effect until a complete test is conducted, with animals under strict quarantine to be tested no sooner than 30 days nor later than 60 days from the date of quarantine. These structured timelines ensure that disease status can be confirmed before movement restrictions are lifted.

What Happens After You Report in Iowa

Making a report sets a structured response in motion. Iowa’s animal disease response system is built around rapid investigation, containment, and — when necessary — eradication. Understanding what to expect after you report helps you cooperate effectively and protect your operation.

If a foreign animal disease was detected in the U.S., IDALS would respond quickly to protect Iowa’s farmers, stop disease spread, and eliminate the disease if it was in Iowa. The response is coordinated at both the state and federal levels.

Here is what typically follows an initial report:

1. Initial assessment call. An animal health official will speak with you to gather preliminary information and assess the urgency of the situation.
2. On-site investigation. A state or federal veterinarian will visit your premises to examine the affected animals and collect samples for laboratory testing.
3. Standstill or movement restrictions. The concept of a standstill order is to halt the movements and transportation for a period of time of all animals in Iowa susceptible to the disease causing the outbreak. This may apply to your premises or a broader geographic area depending on the disease.
4. Quarantine establishment. The chief of the division of animal industry shall take such action as necessary for the prevention and suppression of such disease, including establishment, enforcement, and maintenance of quarantines.
5. Control and monitoring zones. Once exposed farms are identified, disease control areas are established around these farms, allowing animal health officials to further expand their investigation to farms housing animals susceptible to the disease located near the exposed farms.
6. Epidemiological tracing. Officials will trace animal movements in and out of your facility going back at least 30 days to identify other potentially exposed premises.

IDALS FAD response plans are living documents, regularly updated as new information is learned through scientific discoveries, lessons shared from outbreak responses, and feedback from stakeholders. Iowa also coordinates with the Iowa DNR, which contains information and guidance for disposing of animal carcasses that have died from disease or disasters.

Throughout the response, IDALS works with the Center for Food Security and Public Health at Iowa State University, which provides technical expertise and disease-specific resources. You can also review how other states handle post-report response by reading about livestock disease reporting in Florida and livestock disease reporting in California.

Penalties for Failing to Report in Iowa

Iowa takes non-compliance with livestock disease reporting requirements seriously. Failing to report a suspected or confirmed reportable disease — whether through negligence or intentional concealment — exposes you to regulatory, civil, and professional consequences.

Failure on the part of owners to comply with the letter or spirit of these methods and rules shall be considered sufficient cause for immediate cancellation of the cooperative agreement with them by state and federal officials. This can affect your ability to participate in federal programs, receive indemnity payments, and operate under cooperative agreements that many Iowa producers depend on.

For licensed and accredited veterinarians, the consequences extend to professional standing. Failure to immediately report to State or Federal officials all diagnosed or suspected cases of foreign animal diseases such as classical swine fever, foot-and-mouth disease, vesicular stomatitis, rinderpest, African swine fever, avian influenza, and Newcastle disease of poultry is listed as a specific compliance failure that can trigger formal action against a veterinarian’s accreditation status.

Beyond regulatory penalties, the financial consequences of unreported disease spread can be severe for the individual producer and the broader industry:

• Loss of indemnity eligibility — producers who fail to report in a timely manner may forfeit compensation for depopulated animals
• Expanded quarantine zones — delayed reporting allows disease to spread, leading to larger and more costly control areas
• Market access restrictions — Iowa’s trading partners, both domestic and international, can restrict purchases from the state during an active outbreak
• Civil liability — if unreported disease spreads to neighboring operations, affected parties may pursue civil remedies
• Loss of livestock dealer permits — the department may revoke or refuse to issue or renew a livestock dealer permit, pig dealer license, or livestock dealer agent permit for violations of state animal health regulations

Producers in Iowa can also reference how neighboring states structure their enforcement frameworks. See livestock disease reporting in Colorado for a comparison of penalty structures in another major agricultural state.

Iowa’s livestock disease reporting system ultimately depends on a culture of transparency and shared responsibility. Every producer, veterinarian, and farm worker who understands their role — and acts on it — helps protect the health of Iowa’s $40+ billion agricultural economy and the livelihoods that depend on it. When you see something that concerns you, the right call is always to make the call.
