Antimicrobial Stewardship

The Stewardship section of AUS creates materials and presents information to help California livestock producers and veterinarians understand and implement the judicious use of antimicrobials. To accomplish this, the team publishes resources such as Best Management Practices on relevant topics and provides continuing education sessions for veterinarians. We are guided by a set of values outlined in our document, Principles of Antimicrobial Stewardship .

Program notes are provided to update the reader on the progress the AUS program has made on the guidelines* that will inform measures to mitigate antimicrobial resistance. Notes are current as of publication.

Commitment to Partnership

Program Note: Guidelines on VCPR Practice Models have been developed for interactions with youth agriculture groups and additional models are forthcoming.
VCPR Example – Agent Authorization: This document is not required for youth agriculture participation, or to establish or maintain a VCPR. The intent of the document is to inspire creative solutions within the context of the definition of a VCPR in California. A VCPR is validated by the communications and actions between the veterinarian and the client.
Nominate Veterinary Shortage Areas Help guide CDFA’s efforts to nominate veterinary shortage areas for USDA’s Veterinary Medicine Loan Repayment Program (VMLRP). The program helps qualified veterinarians offset a significant portion of the debt incurred in pursuit of their veterinary medicine degrees in return for their service in certain high-priority veterinary shortage situations.

Animal Health and Disease Prevention

Program Note: Best management practices and syndrome-specific antimicrobial stewardship guidelines will be developed for each livestock production type after information is gathered from California livestock owners in order to recommend effective, practical, and scientifically-based practices.
The Vaccine Handling Guidelines provide direction for producers and veterinarians of all livestock species to assist with creating an effective vaccination program. This document includes five eye-catching infographics describing the following key components: planning; storage; transportation; administration; and follow-up, monitoring & records, with the goal of maximizing disease prevention through focused and effective vaccination plans. The Resources for Veterinarians document includes additional research-based information and resources for expanding your knowledgebase and enhancing your practice.

These cow calf guidelines provide direction for producers and veterinarians to assist with the detection, prevention and management of the top three diseases that can lead to antibiotic use in cow calf operations: pinkeye, scours, and bovine respiratory disease.

The documents titled Strategies for Management are infographic documents designed for producers. The documents titled Practical Guide for Veterinarians are to be used by veterinarians in addition to the infographic guidelines.

Antimicrobial Stewardship During COVID-19 Pandemic: COVID-19 has brought numerous challenges to the animal production industry. Some of these challenges are affecting the typical chain of food distribution. This printer-friendly infographic lists considerations for the continuation of antimicrobial stewardship in livestock during the COVID-19 pandemic.
The Antimicrobial Stewardship Planning Checklist is designed to help veterinarians engage in conversation with their livestock producers regarding broad, non-species specific health related topics. These topics are general considerations that veterinarians and producers may find useful when developing and implementing on-farm animal health plans. Use of these resources is voluntary and is helpful to facilitate and maintain a veterinarian-client-patient relationship (VCPR).

Antimicrobial Stewardship Planning Checklist One-Page: The one-page checklist format is useful as a quick guide.

Judicious Use of Antimicrobials

** Laws regarding drug use in livestock are established in order to ensure meat, poultry, dairy and eggs are safe for our families to eat and protect animal and human health. Please go to the Federal & State Policy page for more details on current laws.
Guidelines for Judicious Use of Antimicrobials in Livestock: These guidelines are intended to aid livestock owners and their employees responsible for animal care in responsible antibiotic use under the guidance of a veterinarian in compliance with state and federal laws.
Guidelines for Veterinarians: Judicious Use of Antimicrobials in Livestock: These guidelines are intended to serve as an adjunct to professional judgement. They are based on current scientific principles and state and federal laws regarding medically important antimicrobial drug use in livestock.
Responsible Antibiotic Use: This printer-friendly infographic of AUS’ Guidelines for Judicious Use of Antimicrobials in Livestock (see full text in documents above) is intended to help veterinarians, livestock owners, and their employees understand their roles and the necessary actions taken to preserve the effectiveness of antibiotics, also referred to as antibiotic stewardship.

Printing Tip: For best printing results, adjust your Printer Properties to:
Orientation: Landscape and Scale: Shrink to Fit.
CAHFS Antibiogram Development Process: These slides outline the steps involved in creating Minimum Inhibitory Concentration (MIC) data and how the MIC data is used to develop antibiograms based on the process currently utilized by the California Animal Health and Food Safety Laboratory (CAHFS).
California Livestock Antibiograms: A User Guide: This document serves as a guide for veterinarians on how to interpret and apply antibiograms in clinical practice. Antibiograms are a clinical tool that can help optimize veterinary approaches to antimicrobial therapy, specific to a particular bacteria and drug combination. Please note: All CAHFS antibiograms are for advisement only and are intended to be used by veterinarians.
Antimicrobial Selection: Considerations for Veterinarians: This guide provides an overview of concepts to consider when using antimicrobial susceptibility test data to guide clinical decisions.

Opportunities for dairy antimicrobial stewardship continuing education:

In consideration of the ongoing concerns surrounding COVID-19, we are updating the “Partnering for Antimicrobial Stewardship: A Conference for Farmers and Veterinarians in the West” from a live in-person conference to a multi-day, 4-session interactive webinar series; every Wednesday, starting July 8, 2020 at 6-8PM (Pacific Time). We take these actions to ensure attendees may engage with dairy antimicrobial stewardship without concern for their personal health and safety.
