Global Regulations and Guidelines for Adverse Event Reporting in Animal Health: A Comparative Analysis Across FDA, EMA, and APVMA

Adverse event (AE) reporting in animal health is a critical component of veterinary pharmacovigilance, designed to safeguard animal welfare, public health, and the environment. With the growing use of veterinary medicinal products (VMPs) globally, regulatory bodies across regions have developed robust frameworks to monitor and manage adverse events related to these products. Among the most influential are the U.S. Food and Drug Administration (FDA), the European Medicines Agency (EMA), and the Australian Pesticides and Veterinary Medicines Authority (APVMA). This article presents a comparative analysis of AE reporting frameworks in these three regions, explores their similarities and differences, and discusses their broader impact on global animal health.

The Role of Adverse Event Reporting in Animal Health

Adverse event reporting in veterinary medicine helps identify product-related risks post-authorization that may not have been evident during clinical development. These can include adverse drug reactions, lack of expected efficacy, and environmental issues. Systematic and timely reporting enables regulators to update safety information, impose restrictions, or even withdraw products, ensuring responsible usage in animals and minimizing risks to humans and ecosystems.

United States – FDA (Center for Veterinary Medicine - CVM)

In the U.S., the Center for Veterinary Medicine (CVM), a division of the FDA, oversees the pharmacovigilance of veterinary products through its Pharmacovigilance Program. The FDA mandates that manufacturers, distributors, and veterinarians report:

• Serious adverse drug events

• Product defects and contamination

• Lack of efficacy and medication errors

• Adverse human reactions due to animal product exposure

Reports must be submitted through Form FDA 1932a or via the Adverse Event Reporting System (AERS). There is also emphasis on Veterinary Feed Directive (VFD) products, especially with antimicrobial stewardship efforts under frameworks like the FDA Guidance for Industry (GFI) #209 and #213.

The U.S. system is relatively transparent, with publicly accessible databases and increasing digital integration for stakeholders. The FDA also collaborates with the USDA for zoonotic disease surveillance, further connecting AE reporting to public health policies.

European Union – EMA (Veterinary Medicines Regulation)

The EMA's regulatory framework is guided by the Veterinary Medicinal Products Regulation (EU) 2019/6, which came into force in January 2022, modernizing the previous Directive 2001/82/EC. The regulation applies across all EU Member States and harmonizes pharmacovigilance for veterinary products.

Key aspects include:

• Mandatory reporting of all serious adverse events and lack of efficacy cases by Marketing Authorization Holders (MAHs), veterinarians, and animal owners

• Use of the Union Pharmacovigilance Database (EVVet) for standardized electronic submissions

• Implementation of signal detection and risk management plans (RMPs) for continual product monitoring

• Specific attention to antimicrobial resistance (AMR) and the One Health approach, ensuring environmental and food chain safety

The EMA’s model is more centralized compared to the U.S., with strong alignment across member states. It also facilitates periodic safety update reports (PSURs) and encourages proactive pharmacovigilance through data analytics and risk-based inspections.

Australia – APVMA (Adverse Experience Reporting Program - AERP)

The APVMA governs veterinary product safety in Australia through the Adverse Experience Reporting Program (AERP). The APVMA mandates that registrants report:

• Any suspected adverse effects, including death, illness, or injury in animals, humans, or the environment

• Lack of efficacy or product defects

• Residue violations in food-producing animals

Reports can be submitted via an online portal or by email, and APVMA assesses each case for causality and risk. Australia’s regulatory model emphasizes:

• Post-market surveillance with a focus on high-risk categories

• Periodic evaluation of registered products through chemical review programs

• Public sharing of product safety updates and labeling changes

The APVMA’s framework reflects Australia's unique environmental and agricultural context, including specific protocols for wildlife and aquaculture species, and strong biosecurity controls for imported veterinary medicines.

Comparative Overview

Impact on Global Animal Health

Despite regional differences, a growing trend toward harmonization and data interoperability is evident. International bodies such as the World Organisation for Animal Health (WOAH) and the VICH (International Cooperation on Harmonisation of Technical Requirements for Registration of Veterinary Medicinal Products) are facilitating convergence of guidelines, enabling more consistent global surveillance.

By improving cross-border data sharing, especially for transboundary diseases, these frameworks collectively strengthen early warning systems, reduce antimicrobial resistance risks, and ensure that veterinary medicines remain both effective and safe. Moreover, increased transparency and digitization are empowering veterinarians and farmers with real-time safety insights.

Challenges and Opportunities

While each region has made strides in refining its AE reporting systems, several challenges persist:

• Underreporting due to lack of awareness or perceived complexity

• Variability in data formats and causality assessments

• Limited real-time analytics in some regulatory systems

• Need for harmonized digital tools for global pharmacovigilance

Opportunities for improvement include AI-based signal detection, mobile-enabled AE reporting, and integration of veterinary EHR systems with national reporting databases. Global collaboration will be key to overcoming these limitations and achieving a more proactive and predictive approach to animal health safety.

Conclusion

Adverse event reporting in veterinary medicine is a cornerstone of animal health and welfare. By analyzing and comparing the regulatory frameworks of the FDA, EMA, and APVMA, we gain insights into how different regions are addressing the safety challenges of modern veterinary practice. While diverse in execution, these systems share a common goal—ensuring the responsible use of veterinary products through transparent, timely, and data-driven surveillance. As global animal health becomes increasingly interconnected, harmonized and digitized pharmacovigilance will be essential to protecting both animal and public health.
