Fighting antimicrobial resistance in Africa: how to better take into account the needs of small African farms

Antimicrobial resistance in Africa is becoming a great cause of concern. The issue, however, is not a simple one, since although the continent has the lowest use of antimicrobials in livestock production, pathogens of animal origin have been associated with high antimicrobial resistance. An article published in Emerging Infectious Diseases identifies the culprits behind this paradox, namely, a lack of knowledge and a misuse of antimicrobials in many African farms. To address this major public health problem, a research team led by Christian Ducrot and François Roger—researchers at INRAE and CIRAD respectively—advocate for policies aimed at improving access to veterinary drugs and developing innovative social and technical interventions for the use of antimicrobials, adapted to small African farms and designed directly with the farmers.

The paradox of antimicrobial resistance in African livestock

According to official international data, Africa has the lowest antimicrobial use in animals in the world, adjusted by animal biomass. Still, a closer look shows a high prevalence of antimicrobial resistance in foodborne pathogens isolated from animals and animal products in Africa.

A study conducted by researchers from INRAE, CIRAD, ILRI, IRD and the University of Copenhagen sheds some light on the situation. By analysing literature based on qualitative interviews with the farmers, the authors were able to identify a lack of knowledge of the phenomenon of antimicrobial resistance and a tendency to use antimicrobials in their livestock production in an uninformed and even imprudent fashion, without any concern for the risks involved.

Given the increase in the development of livestock farming—to meet growing demand for protein—these practices constitute a serious public health problem.

A call for policies tailored to African farms

The team of researchers advocates for policies that take into account the specific challenges of livestock production in Africa: both for commercial producers and small family farms.  

These policies must respond to the dual challenge of simultaneously improving access to veterinary drugs while strengthening regulation of their use on livestock.

On one hand, antimicrobial use in large commercial farms must be regulated. On the other, family farms are struggling to access professional veterinary advice and health treatments. This hampers their capacity to change their practices, adopt innovations, cope with more demanding regulations and higher production standards.

Possible solutions for small farms 

Researchers propose to develop strong public policies—that promote access to veterinary services for family farms—and to introduce better regulations for farming practices—that provide access to training and advice from professional veterinarians or paravets.

Stakeholder involvement in participatory approaches—in a one health framework—is essential to ensure the effectiveness of any action plan or regulation, and to protect small family farms.

Researchers also emphasize that an effective application of these policies will depend on a key factor: minimising any adverse health and socioeconomic impact on the farmers’ standards of living, especially in the most vulnerable regions.

Antimicrobial resistance, a global public health issue

Although the routes of transmission of antimicrobial resistance from animals to humans and vice versa have not yet been sufficiently studied in Africa, the situation is of great concern for public health. The likelihood of resistance being transmitted to farmers and consumers through meat and other products of animal origin is high.

In Africa, as anywhere else, the zoonotic contribution to human antimicrobial resistance only adds to the already growing resistance associated with antimicrobials commonly prescribed to humans. Antimicrobial resistance is an issue that affects the whole planet, but it is still too often underestimated.

In fact, the World Health Organization has declared antimicrobial resistance to be one of the top ten global public health threats.

Bacterial viruses: our faithful allies against antibiotic resistance

PRESS RELEASE -Viruses may sometimes be our enemies, but they can also be our allies. When our medicines are no longer effective, viruses can be valuable partners in defeating pathogenic bacteria. But more importantly, viruses do not lead to new antibiotic resistance in bacteria. Such was the conclusion of an INRAE study, published on 25 October 2021 in the journal ISME Communications.

A novel antibiotic resistance mechanism

PRESS RELEASE - Bacteria make use of a number of natural resistance strategies to overcome antibiotics. And it seems that this bacterial toolbox may be much more varied than previously thought. Scientists at the Institut Pasteur, in collaboration with Inserm, INRA, the CNRS and the Weizmann Institute of Science in Israel, have recently revealed an entirely unknown resistance mechanism in Listeria monocytogenes bacteria. When these bacteria come into contact with antibiotics that target ribosomes and block protein synthesis, they are capable of splitting their ribosomes in two to recycle them and to restart protein production. This mechanism depends on the expression of the gene hflXr. The findings were published on 13 December 2018 in the journal PNAS.

Gwenaël Vourc’h: the One Health approach, now more than ever

Research Director at the Epidemiology of Animal and Zoonotic Diseases (EPIA) Joint Research Unit, for the past two decades Gwenaël Vourc’h has focused on ecology, biodiversity and emerging infectious diseases - topics of particular interest now with the Covid-19 pandemic, which has shed light on the urgent need to consider human health as inextricably linked to the health of our ecosystems.
