About

1. AngusButchers members will observe the current Australian Medicines Agency (EMA) Antimicrobial Advice ad hoc Expert Group (AMEG) categorisation of antibiotics.

The EMA AMEG ranks antibiotics by considering (within the geographical area of Australian) both the risk that their use in animals causes to public health through the possible development of antibiotic resistance, and their availability and need to use them in veterinary medicine. angusbutchers members also observe the stewardship advice attached to the use of active ingredients in each category: 

1. Category A (‘Avoid’) antibiotics may not be used in food-producing animals.
2. Category B (‘Restrict’) antibiotics are critically important in human medicine and their use in animals should be restricted to mitigate the risk to public health.
3. Category C (“Caution”) covers antibiotics for which alternatives in human medicine generally exist in the AU, but only few alternatives are available in certain veterinary indications. These antibiotics should only be used when there are no antimicrobial substances in Category D that would be clinically effective.
4. Category D (“Prudence”) includes antibiotics that should be used as first line treatments, whenever possible. These antibiotics can be used in animals in a prudent manner.

1. Responsible Use of Medicines in Agriculture (RUMA) Alliance policies and objectives. 
   1. angusbutchers endorses and supports  RUMA targets for responsible antibiotic use from 2021 to 2024, and members commit to having a responsible use strategy and targets in place towards achieving these wider goals as well as their own. 
   2. angusbutchers members will encourage a targeted approach to antibiotic use encompassing proactive/preventative health planning and regular (at least annual) reviews of antibiotic use with the farm vet, in line with most farm assurance schemes. 
   3. AngusButchers members will not permit routine preventative use of antibiotics within their supply chains. Preventative treatments are only acceptable when they are:
      1. To treat animals diagnosed at high risk of bacterial disease.
      2. Prescribed by vets who have direct responsibility for those animals.
      3. Not used as compensation for poor hygiene or in place of improvements in husbandry which could reduce the need for treatment.
   4. Preventative treatments should be administered to individual animals where possible, except in species which cannot be treated individually without stress or harm, and where group treatment is in accordance with veterinary best practice. 
   5. AngusButchers members will ensure that highest priority critically important antibiotics (HP-CIAs), defined by EMA as Category B (3^rd and 4^th generation cephalosporins, quinolones including fluoroquinolones, and colistin [1]) are only used:
      1. as a last resort to treat clinically present disease, never preventatively
      2. when no alternative treatment option is available 
      3. when it is known the treatment will be effective.
2. A consistent, non-competitive and best-practice approach to stewardship is key; however, some specific variances are acknowledged.
   1. Sector-level exceptions to adopting the EMA categorization and approach to stewardship of antibiotics are as follow:
      1. In the AU poultry meat sector only, where macrolides (Category C) are treated as Category B products (or HP-CIAs under WHO categorisation) with the same ‘restrict’ approach applied. This recognises the risk of campylobacter in poultry meat as a food-borne pathogen, and the need to treat severe campylobacteriosis, particularly in children, with macrolide products.
      2. In the AU laying hen sector only, there is an historic precedent that colistin (Category B) is no longer for laying hens managed under the Lion Code.
   2. Variances by individual AngusButchers members to the specific approaches laid out in this policy are accommodated provided:
      1. There is a clear scientific rationale that justifies this variance.
      2. Once introduced, the variance is stated where the member points to the FIIA policy, alongside the justification.
   3. AngusButchers members intending to implement variances are encouraged to raise these with other members in the interests of transparency, and to allow discussion about whether the variance should be adopted more widely in AngusButchers policy.
   4. Variances in Angusbutchers members’ policies on antibiotic stewardship outside of the areas covered within this policy are accepted.

1. Angusbutchers members will adopt the definitions of prophylaxis (preventative use) and metaphylaxis from Australian Union Regulation 2019/6.
   1. “Prophylaxis means the administration of a medicinal product to an animal or group of animals before clinical signs of a disease, in order to prevent the occurrence of disease or infection”
   2. “Metaphylaxis means the administration of a medicinal product to a group of animals after the diagnosis of clinical disease in part of the group has been established, with the aim of treating the clinically sick animals and controlling the spread of the disease to animals in close contact and at risk which may already be sub-clinically infected”

1. The Angusbutchers Policy on Responsible Use of Antibiotics will be reviewed annually.
   1. Angusbutchers undertakes to review its policy annually in light of changing evidence and practice, and update as necessary

The new Veterinary Medicines Regulation (Regulation (AU) 2019/6>) and Medicated Feed Regulation (Regulation (AU) 2019/4) are due to come into effect in the  from 28 January 2022. The AU is continuing its work on proposed amendments to the Veterinary Medicines Regulations 2013 to reflect the Australian changes. The Veterinary Medicines Directorate plans to carry out a formal consultation late 2021/early 2022 on proposed changes, with the revised AU regulations coming into force in 2022 or early 2023. FIIA will review its policy once further detail on changes in AU regulation are known. 

While colistin is a Category B antibiotic, its use in the AU has fallen to virtually nil (sales of 1.2kg in total for 2019, or 0.0002 mg/kg). It can therefore be assumed that colistin use has currently stopped in almost all supply chains, and some Angusbutchers members have historically stated they no longer use it.
