Summary: The use of antimicrobial drugs leads to a relative increase in resistant bacteria, even though antimicrobial resistance is an old and naturally occurring phenomenon in bacteria. In intensive livestock production systems, resistant bacteria can spread easily between animals and this can be made worse if biosecurity is inadequate. Food is likely to be quantitatively the most important source of transmission from livestock to humans, although there is no direct link between rise of antimicrobial resistance in humans in relation to food consumption. In order to build successful solutions to the problem of antimicrobial resistance, is essential to understand what drives the spread of AMR in animal production.
The effect of extensive and organic farming systems and antimicrobial use on the rise and spread of AMR are discussed. However it is still not clear how sustainable agriculture systems can help fight AMR.
It is now accepted that increased antimicrobial resistance (AMR) in bacteria affecting humans and animals in recent decades is primarily influenced by an increase in usage of antimicrobials for a variety of purposes, including therapeutic and non-therapeutic uses in animal production. Antimicrobial resistance is an ancient and naturally occurring phenomenon in bacteria. But the use of antimicrobial drugs – in health care, agriculture or industrial settings – exerts a selection pressure which can favour the survival of resistant strains (or genes) over susceptible ones, leading to a relative increase in resistant bacteria within microbial communities.
In intensive livestock production systems, resistant bacteria can spread easily between animals and this can be exacerbated if biosecurity is inadequate.
In aquaculture, AMR can develop in aquatic and fish gut bacteria as a result of antimicrobial therapy or contamination of the aquatic environment with human or animal waste. The extent and persistence of antimicrobial residues in aquatic systems is unknown and current evidence is conflicting.
Food is likely to be quantitatively the most important potential transmission pathway from livestock to humans, although direct evidence linking AMR emergence in humans to food consumption is lacking.
An improved understanding of the epidemiology of AMR emergence and spread in animal production will provide an essential foundation for successful mitigation strategies.
The relationships between different types of farming systems and both AMU and the emergence and spread of AMR are discussed in this paper, including extensive and organic systems, but there is still a notable lack of knowledge on the role that sustainable agriculture systems can play in combatting AMR.
Most importantly, future research needs to involve an interdisciplinary (e.g. One Health) approach, integrating agricultural, medical, environmental and social sciences, and especially recognizing the importance of human behaviour. A set of specific recommendations to fill current knowledge gaps is presented in the final section of this technical paper.

Step-by-step plan for water sampling

1. Take a bottle that is as clean as possible and rinse it several times with the water to be analysed. A number of labs also have receptacles available.
2. Wash your hands thoroughly.
3. For a sample directly from a reservoir you take a mixed sample of different subsamples. You should preferably scoop these subsamples about 30 cm below the water surface. After good mixing, the receptacle can be filled.
4. Follow the following procedure for a sample from a tap:
– To know the quality of the starting water (the source), choose a tap as close to the source as possible.
– To check the quality at the drinking points, take a sample from a tap that is as far from the source as possible.
5. Clean the tap well, preferably also with an alcohol tissue.
6. If you want to know the quality of the starting water (the source), let the tap run for some minutes. To detect problems with biofilm formation in the pipes or to check if a disinfectant works effectively, let it run only for a short time.
7. Fill the receptacle for bacteriology first, then the receptacle for chemical parameters.
8. It is important that the samples reach the lab as soon as possible. If this is not possible, make sure that the samples are kept cool (refrigerated) for storage and transportation.

Step-by-step plan for the acidification of drinking water

 

In pigs and poultry, acidification of the drinking water can be a very effective tool to prevent or lower the need for antibiotics. Acidification can have multiple beneficial effects, such as improved palatability and thus water intake, improved digestion, prebiotic effect and reduction of pathogens (e.g., Salmonella). Each type of acid or acid mixture has its own specific properties. Moreover, disinfection products or other compounds present in the water can interfere or react with acids. In some cases, organic acids can cause slime formation due to growth of yeasts and fungi. Always consult your vet/advisor to discuss which acid (mixture) suits your drinking water system and water quality best. Once a suitable acid (mixture) is chosen, the correct dosage is the key to success.

How to determine the correct dosage:

1. Fill a bucket with 10l of the water to be tested.
2. Put on safety glasses and acid resistant gloves.
3. Take a disposable syringe of 10 or 20 ml and fill it with the acid (mixture) to be tested.
4. Add 5 ml of the acid (mixture) to the water and measure the pH with a pH strip or pH meter (both for sale at the pharmacy). Repeat this step until you reach the desired pH (typically around pH 4; discuss this with your vet/advisor)
5. Write down how much acid (mixture) you added to the water (= ‘x’ ml)
6. Calculate the dosage:
x millilitre of acid added to 10 litres of water =>
DOSAGE = x/10 litre of acid per 1000 litre of water
7. Repeat this procedure every time the water source or type of acid (mixture) is changed

Microbial toxin elimination by selective binding

Every day, farmers all across the world work hard to give their animals the best possible care. However, there are many challenges among them how to find balanced and cost effective feed and how to keep livestock healthy. Moreover, due to climate change, raw materials are even more exposed to increased temperatures and higher humidity, what results in microbial contamination and subsequent toxin production, for example mycotoxins what poses a serious threat to animal health and performance.

Today’s solutions are innovative concepts dealing with climate change and increasing feed efficiency and customer convenience. The negative aspects of climate change can be easily targeted by providing the animals cost effective multi-level nutritional concepts able to prevent these issues by selective toxin absorption (avoiding nutrient malnutrition), create a healthy gut and gastrointestinal barrier, supplemented by ingredients promoting immune boosting and liver function. This is all combined in concepts such as VitaFix, an alternative for antibiotics and combining advanced adsorbing agents together with organic acids and natural antioxidants. Farmers across the globe are very satisfied with such multi-level solutions as witnessed in the video.

Aim for zero antibiotics by 3 step approach

Every year 700000 people die because of antimicrobial cross resistance. By 2050 the number will be multiplied by ten. Every 45 seconds someone dies because of antimicrobial cross resistance. By 2050 every 3 second someone will die.

It is clear that we have to aim for minimal – preferentially zero – use of antibiotics. Farmers can aim for use of zero antibiotics via a simple 3-step approach.

The first step deals with using a benchmark tool. Different examples are available such as undependent ones like Biocheck or commercial ones as shown in current video. Based on the outcomes of the benchmark tool, your veterinarian or coach at the farmer site can advise you on possible strategies to reduce antibiotics and subsequent antibiotic resistance. Finally, next to management and veterinarian solutions, your adviser can advise plenty of feed solutions together with nutritionists for alternative intervention at the different levels of the animal in order to secure animal health and performance.

Farmers across the globe are very satisfied with such simple 3-step approach as witnessed in the video.

100 Antimicrobials in agriculture and the environment: reducing unnecessary use and waste (Research report; Neil, 2015)

 

 

Significant Impact Group(s): AMU reduction strategies \ Legislation and incentives; Government
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep;
Summary: This report presents focus areas to globally reduce the use of antibiotics in agriculture and the environment:
1. Agree on targets to reduce antibiotic use in food production, to an acceptable level per kilogram of livestock and fish, together with limitations of use of antibiotics that are important for humans.
2. Agree on minimum limits for antibiotic environmental waste, which should be taken into consideration by pharmaceutical companies, healthcare buyers and regulatory agencies everywhere.
3. Improved surveillance at an international level to monitor antimicrobial use and waste, and evaluate progress towards global targets.
Interventions in agriculture that could change antibiotic use include improvements in infection control, better animal husbandry practices, greater use of vaccines and the adoption of diagnostic devices to improve veterinary prescribing practices.
This report also discusses the roles of taxation, subsidies, and regulation in reducing the risks associated with agricultural use of antibiotics and environmental contamination.
This paper proposes three broad interventions to take bold global action to substantially reduce the use of antibiotics in agriculture and the quantities being dispersed into the environment:
1. A global target to reduce antibiotic use in food production to an agreed level per kilogram of livestock and fish, along with restrictions on the use of antibiotics important for humans.
a. We need to reduce global levels of antibiotic use in agriculture, to an agreed limit for each country, but it should be for individual countries to decide how best to achieve this goal – a global target would make this possible. We believe an ambitious but achievable target for reducing antibiotic use in agriculture is needed, to reduce use over the next 10 years. There are countries that have advanced farming systems with very low levels of antibiotic use, particularly in Scandinavia. Denmark has combined low use with being one of the largest exporters of pork in the world. Reducing levels of use to that of Denmark for example, an average of less than 50 milligram (mg) of antibiotics used a year per kilogram (kg) of livestock in the country, may be a good starting point for such a target. We think this would be feasible without harming the health of animals or the long-term productivity of farmers. This is based on our understanding of academic literature and case studies. The exact level of a target would, however, need to be discussed and tested by experts. Low and middle-income countries may need more time to achieve such a target, while many of these countries may already be below the threshold.
b. As well as reducing the quantity of use, the types of antibiotics used are also important. Currently many antibiotics that are important for humans are used in animals. We believe that countries need to come together and agree to restrict, or even ban, the use of antibiotics in animals that are important for humans.
2. The rapid development of minimum standards to reduce antimicrobial manufacturing waste released into the environment. This needs to be viewed as a straightforward issue of industrial pollution, and it is the responsibility of all actors in the supply chain to ensure that industrial waste is treated properly as a matter of good manufacturing practice. The risk of drug resistance must urgently become a key environmental consideration for all pharmaceutical companies, healthcare buyers and regulatory agencies everywhere. Failing to do this does most harm to the health of populations living near the manufacturing sites who are exposed to polluted water, and are in a way are paying the price of cheap antibiotics for the rest of the world. But in the long-term, we know that resistance spreads and these strains will in time likely become a global problem.
3. Improved surveillance to monitor these problems, and progress against global targets. There remain too many knowledge gaps regarding patterns of antimicrobial use in agriculture and release during manufacturing, and what this means for resistance and, ultimately, human health. This needs to change if meaningful progress is to be made.
As with the human health aspects of AMR, these are complex issues that require concerted, coordinated action at an international level. Drug-resistant infections know no borders and do not respect barriers between industry, regulators and buyers, or between animals, humans and their wider environment. There are encouraging signs of some governments adopting a broad ‘one health’ approach to tackling the issue of resistance, but it is an approach that needs to be replicated by others. We believe that success can only be achieved by considering a full range of interventions:
• In agriculture, these should take into account the key drivers of the real or perceived need for antibiotics, whether for use as therapy, prophylaxis (prevention), or growth promotion. Interventions will no doubt include improvements in infection control, better animal husbandry practices

86 Methicillin-Resistant Staphylococcus aureus Strains in Swiss Pigs and Their Relation to Isolates from Farmers and Veterinarians (Research paper; Kittl, 2020)

 

 

Significant Impact Group(s): Pathogen management
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep;
Age: Different for different species;
Outcome Parameter(s): MRSA prevalence in livestock at the slaughterhouse; MRSA prevalence in meat at retail outlets; Prevalence in veterinarians and farmers
Summary: Methicillin-resistant Staphylococcus aureus (MRSA) can lead to serious disease in humans, and since this bacteria is often found in livestock can have potentially large impact on public health. Farmers and veterinarians are especially at risk due to their close contact with animals. Our work demonstrates a dramatic increase in MRSA prevalence in Swiss pigs, from 2% in 2009 to 44% in 2017. Sequencing of the bacterial genes allowed us to show a close association between farmer and pig strains as well as veterinarian and horse strains, indicating that pigs and horses are a likely to be a source of human colonization. In this study it was also shown pig spa t011 strains are probably less likely to colonize humans than are pig spa t034 strains. This research may provide a basis for a more accurate risk assessment and preventive measures.

85 A ‘meta-analysis’ of effects of post-hatch food and water deprivation on development, performance and welfare of chickens (Research paper; De Jong, 2017)

 

 

Significant Impact Group(s): Feed / gut health \ Feeding management – Feeding management ; Water
Species targeted: Poultry;
Age: Young;
Outcome Parameter(s): body weight; cumulative food intake; FCR; mortality; relative yolk sac weight
Summary: This study reports results collected in other studies showing that post-hatch food deprivation or food and water deprivation (PHFWD) for approximately 24 hours can lead to significantly lower body weights compared to early fed chickens up to six weeks of age. Body weights and food intake were reduced more the longer the food and water deprivation lasted. PHFWD also has negative effects on the development of liver and pancreas, and delay the development of duodenum, jejunum and ileum. These effects were observed mainly in the first week of age. As a conclusion, findings also suggest a chicken welfare is lowered for PHFWD, however, additional studies are recommended on the effect of PHFWD containing a wider range of variables, including behaviour and disease resistance, in the short-term as well as long-term.
