Reducing health risks from antimicrobial resistance (AMR)

The development of resistant strains of disease-causing microorganisms is an important health issue of global concern. When microbes such as bacteria, fungi, parasites, and viruses become resistant to antimicrobial substances, the diseases they may cause become more difficult or impossible to treat. Resistance is developed by the indiscriminate use of antimicrobials and places human health at risk.

The discovery of antibiotics revolutionized medicine, creating a belief that a 'magic bullet' had finally been found to control bacterial diseases. Antibiotics, a class of antimicrobial agents, kill or inhibit the growth of bacteria, but they have no significant effect on other types of microorganisms such as viruses.

"Bacteria, the oldest life form on this planet have survived 4 billion years due to their remarkable ability to adapt to changes in their environment... any 'resistance' gene present in any member of any species in the microbiome has the potential to transfer to any other species" says Dr Peter Smith of Ireland.

National delegates representing China, Malaysia, the Philippines and Viet Nam; fish health experts from India, Ireland, the Netherlands, the Philippines, Viet Nam and the United States; and representatives of the Government of India, Nitte University, FAO, NACA and the OIE are participating at an international workshop to address antimicrobial use (AMU) and AMR in aquaculture, convened by FAO and Nitte University, in Mangalore, India, 10-12 April.

Dr J.K. Jena, Deputy Director General of the Indian Council of Agricultural Research, highlighted the importance of aquaculture and the need to address issues related to diseases and the irresponsible use of veterinary drugs. "Strengthening laboratory networks and increasing AMU/AMR awareness as well as research on safety, efficacy and withdrawal period, resistance mode and process of transfer of resistance for different antimicrobials are needed", he said.

In his Presidential Address, the Vice-Chancellor of Nitte University, Professor Ramananda Shetty, urged interdisciplinary studies to be undertaken as all sectors have a responsibility towards this burning problem. He emphasized the need for regulation of antibiotic sales, responsible implementation of treatment regimens by the doctors and diligent attention to medical advice by the patients.

The complexity of the issue calls for a "One Health" platform involving both human medicine and the agriculture sector in an interdisciplinary and integrated approach to tackle what is very much a common problem. This approach combined with concerted actions at the national level that span policy and regulatory spheres, preventive actions and engagement with producers and other food value chain stakeholders are needed to prevent and reduce AMR.

Detailed guidance was provided on developing the aquaculture component of the National Action Plans (NAP) on AMR covering the four focus areas of FAO's Action Plan on AMR: awareness, governance (NAP), evidence (usage and surveillance) and practice (prudent use). National delegates will further develop the action plans, disseminate the scientific information delivered during the workshop and create awareness of AMR issues among national stakeholders.

Protecting Pristine Paradise Palau: Technical deliberations tackle regulations on aquatic biosecurity and biofouling management

National Consultation on Biosecurity Regulations for Aquatic Animals in Support of the Biosecurity Act of 2014, 28 March 2017, Koror, Palau

Some thirty participants representing the government (Bureau of Justice: Office of the Attorney General and Division of Fish and Wildlife Protection) Bureau of Agriculture (BOA including the Division of Biosecurity), Bureau of Customs and Border Protection, Environmental Quality Protection Board, Ngatpang State; the private sector (BIOTA, Inc., Coral Reef Research Foundation, Palau Aquaculture Cooperative Association, Palau Conservation Society, Environment, Inc.); and the academe (Palau Community College) met on 28 March during a national consultation held at the Palasia Hotel. The participants deliberated on the draft regulations on aquatic biosecurity and biofouling management, actions that are intended to protect Palau's young and growing aquaculture sector, as well as its exquisite coral reefs and lagoons.

Aquaculture is an important source of biological invasions, either because the organisms being raised are aquatic invasive species or because of the presence of hitchhikers in imported shipments. Aquaculture organisms can also carry diseases which can impact the aquaculture industry and may spread to native species. In order to reduce pressures on wild marine fish and other marine organisms of economic importance, the national government has decided to increase aquaculture efforts in both marine and freshwater. While efforts have focused on breeding native fish and shellfish such as groupers, clams and mangrove crabs, there is also pressure to import exotic species, such as tilapia and whiteleg shrimp.

Shipping is also a major concern, as it is has caused the global spread of many marine organisms. All groups of marine organisms may be transported through ballast water, while encrusting organisms (e.g. macro-algae, bivalve mollusks, barnacles, bryozoans, sponges and tunicates), can be carried on ships' hulls. Both may result in the introduction and spread of hard-to-eradicate species that prey on or outcompete native species and foul ports, coasts and aquaculture facilities. These invasive species are a serious threat to the pristine marine waters of Palau. In particular, recreational yachts pose a very high risk for hull-fouling organisms, as they are slow moving and may lack the incentives to keep their hulls immaculate.

With the support of the United Nation's Food and Agriculture Organization (FAO) through TCP/PLW/3601/C1: Strengthening Biosecurity Capacity of Palau, the BOA and other partners in the marine and aquaculture sectors have been working with a team of experts on aquatic animal health, hull fouling, and database development to support the recently approved Biosecurity Act of 2014 that will protect Palau's aquaculture producers from diseases and other threats to their farms.

In opening the national consultation, the Honorable Umiich Sengebau, Minister of Natural Resources, Environment and Tourism, thanked FAO and the participants for supporting this important effort by the BOA to protect Palau's aquaculture industry and our pristine marine environment. "These protections should be adopted and implemented as quickly as possible, and I ask that all here today work together toward this end."

There was strong consensus from the participants of the national consultation to support the implementation of the Biosecurity Act of 2014, finalize the draft regulations and submit a position paper that will enable Palau's President and Cabinet to make informed decisions to support Pristine Paradise Palau through a culture of protection and conservation.

New publication online: Handbook for fisheries socio-economic sample survey - principles and practice

Click to enlargeSocio-economic data are a key component of the scientific advice required for the participatory management of fisheries, yet in many countries these data are limited, usually because of a lack of technical capacity for their collection. The aim of this handbook is to act as a practical guide for addressing the limited availability of socio-economic data as well as a general lack of capacity for socio-economic data collection. Specifically, it addresses survey design, data processing, and the analysis and dissemination of this data. The handbook has been written for those planning surveys and coordinating and supervising all the phases of the survey data collection process, from the sampling design to the final estimates, including the organization of the fieldwork.

The handbook consists of three sections. In the first it introduces the basic theory and background required for understanding the socio-economic survey methodologies. The second section moves from sampling design; fleet segmentation; questionnaire design; and training data collectors, to data quality checks and treatment for making estimations. The final section covers the steps required to move from data collection into the calculation of statistics. Indicators, and the methodology used for their calculation, are presented and this is followed by an in-depth and practical example of how the data can be presented and utilized for policy-level decisions.
