Infants and toddlers are highly vulnerable to exposure to lead due to its higher absorption in small children than in adults. This study describes the optimisation and validation of a very sensitive method for the determination of low levels of lead in foods mostly consumed by infants and toddlers. This method, based on inductively coupled plasma-mass spectrometry with a programmable temperature cyclonic spray chamber, attained a limit of quantification (LOQ) of 0.6 or 0.9 µg Pb kg−1 for a liquid or a solid sample, that was improved by a factor 5.6–8.3 compared to the previous method (LOQ: 5 µg kg−1). The analytical method was then applied to 291 food samples from the first French total diet study on infants and toddlers. Lead was detected in most samples at relatively low concentrations (range 0.0–16 µg kg−1). The highest lead concentrations were mainly found in processed food products (e.g. products containing chocolate). © 2017 Elsevier Ltd

Drivers and risk factors for Influenza A virus transmission across species barriers are poorly understood, despite the ever present threat to human and animal health potentially on a pandemic scale. Here we review the published evidence for epidemiological risk factors associated with influenza viruses transmitting between animal species and from animals to humans. A total of 39 papers were found with evidence of epidemiological risk factors for influenza virus transmission from animals to humans; 18 of which had some statistical measure associated with the transmission of a virus. Circumstantial or observational evidence of risk factors for transmission between animal species was found in 21 papers, including proximity to infected animals, ingestion of infected material and potential association with a species known to carry influenza virus. Only three publications were found which presented a statistical measure of an epidemiological risk factor for the transmission of influenza between animal species. This review has identified a significant gap in knowledge regarding epidemiological risk factors for the transmission of influenza viruses between animal species. © 2017 EcoHealth Alliance

This paper reports the analysis of the impact of Kenya's Cash Transfer for Orphans and Vulnerable Children Programme on the household decisions on productive activities using data from a randomised experimental design. Results show that the programme had a positive and significant impact on food consumption coming from home production, accumulation of productive assets, especially on the ownership of small livestock, and on formation of nonfarm enterprise, especially for females. The programme has provided more flexibility to families in terms of labour allocation decisions, particularly for those who are geographically isolated. The programme was also found to reduce child labour, an important objective of the programme. However, we find very little impact of the programme on direct indicators of crop production. © 2014 © 2014 Taylor & Francis.

One of the most crucial problems with increasing biofuel production is that it competes for natural and agricultural resources with food and food related use, because its main feedstock is agricultural product. Increasing biofuel production therefore is going to have an impact on world agricultural commodity prices and food security. The purpose of this study is to conduct an economic analysis of increasing biofuel production on food security. The own price elasticities of supply equations in the long-term are the key to deciding agricultural commodity price adjustments as a result of an increase in biofuel production. Biofuel production may have a negative impact on food security, but on the other hand they can create opportunities for agricultural development. It is critical to understand that own price elasticity of feedstock supply is a key factor in deciding how biofuel development can contribute agricultural development. Policy makers should recognize the importance of the price elasticity of feedstock supply when they promote biofuel programs and select feedstock to contribute to agricultural development. © 2015 Published by Elsevier Ltd.

In the current situation of endemicity of highly pathogenic avian influenza (HPAI) in Egypt, improving the biosecurity of poultry production has become essential to the progressive reduction the incidence of the disease. A significant proportion of the Egyptian commercial poultry system consists of small-scale poultry producers operating with low to minimal biosecurity measures. An investigation was conducted into the level of adoption of standard biosecurity measures of the small-scale commercial chicken growers, including both farm- and home-based commercial production, input suppliers and other actors along the meat chicken value chain in Fayoum, Egypt. The study which used direct observations and group discussions of nearly 160 participants and structured interviews with 463 respondents, assessed biosecurity implementation to improve management practices and ultimately to control and prevent highly pathogenic avian influenza (HPAI). The survey found that overall, biosecurity measures are rarely implemented in small-scale commercial poultry production units. Compliance with recommended biosecurity practices did not greatly vary from home-based to farm-based commercial production. Furthermore, serious risk practices were identified, such as unsafe disposal of poultry carcasses and potential disease spread posed by poor biosecurity measures implemented during vaccination. HPAI control measures have been ineffective due to limited cooperation between public and private sector, aggravated by the unpopular measures taken in the event of outbreaks and no compensation paid for incurred losses. Outreach and biosecurity awareness raising initiatives should be specifically developed for small-scale producers with the objective of improving general poultry management and thus preventing HPAI and other poultry diseases. © 2012 Elsevier B.V.

Reliable estimation of flood magnitudes corresponding to required return periods, vital for structural design purposes, is impacted by lack of hydrological data in the study area of Lake Victoria Basin in Kenya. Use of regional information, derived from data at gauged sites and regionalized for use at any location within a homogenous region, would improve the reliability of the design flood estimation. Therefore, the regional index flood method has been applied. Based on data from 14 gauged sites, a delineation of the basin into two homogenous regions was achieved using elevation variation (90-m DEM), spatial annual rainfall pattern and Principal Component Analysis of seasonal rainfall patterns (from 94 rainfall stations). At site annual maximum series were modelled using the Log normal (LN) (3P), Log Logistic Distribution (LLG), Generalized Extreme Value (GEV) and Log Pearson Type 3 (LP3) distributions. The parameters of the distributions were estimated using the method of probability weighted moments. Goodness of fit tests were applied and the GEV was identified as the most appropriate model for each site. Based on the GEV model, flood quantiles were estimated and regional frequency curves derived from the averaged at site growth curves. Using the least squares regression method, relationships were developed between the index flood, which is defined as the Mean Annual Flood (MAF) and catchment characteristics. The relationships indicated area, mean annual rainfall and altitude were the three significant variables that greatly influence the index flood. Thereafter, estimates of flood magnitudes in ungauged catchments within a homogenous region were estimated from the derived equations for index flood and quantiles from the regional curves. These estimates will improve flood risk estimation and to support water management and engineering decisions and actions. © 2014 Elsevier Ltd.

South Asia and sub-Saharan Africa are the two regions of the world with the highest concentration of undernutrition. The majority of the nutritionally vulnerable populations in both regions is dependent in some way upon agriculture as a primary source of livelihood. The agriculture sector and wider agri-food system is considered to be central to sustained progress in reducing undernutrition – and yet not enough is known about how to unleash this potential. Recent scoping assessments have also revealed a paucity of information on wider political, institutional and policy-related challenges relating to the agriculture-nutrition nexus globally. Contextualized research into policy processes and the political economy of agriculture and nutrition is needed to better characterize “enabling environments” for agriculture to benefit nutrition, and how these environments can be shaped and sustained. This study aims to contribute to filling this gap, by drawing upon evidence from a set of case studies in South Asia (India, Bangladesh and Pakistan) and eastern Africa (Ethiopia, Uganda and Kenya). In synthesizing results across countries, while recognizing important nuance and detail, we conclude by highlighting four key issues to be addressed. First, improving knowledge and perception of undernutrition and its links to agriculture, on the part of agricultural policymakers and programme managers. Second, generating system-wide incentives for decisions and actions to become more pro-nutrition. Third, developing transparent systems of accountability for nutrition-relevant action throughout the agriculture sector, through linking timely and actionable data and evidence with incentives. And fourth, cultivating and strengthening leadership and capacities at different levels, underpinned by adequate financing. © 2015, The Author(s).

A survey of national animal influenza surveillance programmes was conducted to assess the current capacity to detect influenza viruses with zoonotic potential in animals (i.e. those influenza viruses that can be naturally transmitted between animals and humans) at regional and global levels. Information on 587 animal influenza surveillance system components was collected for 99 countries from Chief Veterinary Officers (CVOs) (n = 94) and published literature. Less than 1% (n = 4) of these components were specifically aimed at detecting influenza viruses with pandemic potential in animals (i.e. those influenza viruses that are capable of causing epidemic spread in human populations over large geographical regions or worldwide), which would have zoonotic potential as a prerequisite. Those countries that sought to detect influenza viruses with pandemic potential searched for such viruses exclusively in domestic pigs. This work shows the global need for increasing surveillance that targets potentially zoonotic influenza viruses in relevant animal species. © 2014 Food and Agriculture Organization of the United Nations.

In December 2011, the European Food Safety Authority awarded a Grant for the implementation of the FLURISK project. The main objective of FLURISK was the development of an epidemiological and virological evidence-based influenza risk assessment framework (IRAF) to assess influenza A virus strains circulating in the animal population according to their potential to cross the species barrier and cause infections in humans. With the purpose of gathering virological data to include in the IRAF, a literature review was conducted and key findings are presented here. Several adaptive traits have been identified in influenza viruses infecting domestic animals and a significance of these adaptations for the emergence of zoonotic influenza, such as shift in receptor preference and mutations in the replication proteins, has been hypothesized. Nonetheless, and despite several decades of research, a comprehensive understanding of the conditions that facilitate interspecies transmission is still lacking. This has been hampered by the intrinsic difficulties of the subject and the complexity of correlating environmental, viral and host factors. Finding the most suitable and feasible way of investigating these factors in laboratory settings represents another challenge. The majority of the studies identified through this review focus on only a subset of species, subtypes and genes, such as influenza in avian species and avian influenza viruses adapting to humans, especially in the context of highly pathogenic avian influenza H5N1. Further research applying a holistic approach and investigating the broader influenza genetic spectrum is urgently needed in the field of genetic adaptation of influenza A viruses.
