The increased attention to the use of farmed insects as a novel protein source has raised the question of the safety of insects as human food and as animal feed. This was the background for the European Union (EU) Commission to mandate the European Food Safety Authority (EFSA) to conduct a review of the current knowledge about biological, chemical and environmental risks associated with production and consumption of insects. National authorities in some EU member states (Belgium, the Netherlands and France) have conducted national assessments (ANSES, 2015; FASFC, 2014; NVWA, 2014). However, in the EU, existing regulations constitute legal barriers for marketing insects for human consumption and as protein in animal feed for food producing animals.

OBJECTIVE: To illustrate the use of needs-based planning in the identification of physician surpluses and deficits and of resource misallocations within a provincial medical system at a time when provincial governments and medical associations across the country are faced with funding constraints for physician services. DESIGN: For each of 4 regions in Manitoba, the authors analysed residents' rates of physician visits (whether within the resident's own or another region). Residents' need for physician contact was estimated by means of a statistical analysis of the data on contacts in relation to age, sex and health-related indicators, and the rates of visits needed and actually made were compared. PARTICIPANTS: All Manitoba residents. OUTCOME MEASURES: Numbers of generalist physicians (general practitioners, family physicians, general internists and general pediatricians) needed to serve each region, and the extent of physician surplus and deficit in each region. RESULTS: There appeared to be a surplus of physicians in most of urban Manitoba but deficits in northern Manitoba and some parts of the rural south. General internists and general pediatricians in Winnipeg provide a significant part of the ambulatory care that is provided by general practitioners in other parts of the province. The provincial government currently spends more per resident to provide physician services in areas of physician surplus than in areas of physician deficit, although the patterns are inconsistent. CONCLUSIONS: Needs-based planning is possible. If provinces are intent on controlling physician numbers and expenditures, it makes sense to manage the implications of doing so.

Open Access Journal; Published online: 25 Sept 2019 ; Scapsipedus icipe Hugel and Tanga (Orthoptera: Gryllidae) is a newly described edible cricket species. Although, there is substantial interest in mass production of S. icipe for human food and animal feed, no information exists on the impact of temperature on their bionomics. Temperature-dependent development, survival, reproductive and life table parameters of S. icipe was generated and integrated into advanced Insect Life Cycle Modeling software to describe relative S. icipe population increase and spatial spread based on nine constant temperature conditions. We examined model predictions and implications for S. icipe potential distribution in Africa under current and future climate. These regions where entomophagy is widely practiced have distinctly different climates. Our results showed that S. icipe eggs were unable to hatch at 10 and 40˚C, while emerged nymphs failed to complete development at 15˚C. The developmental time of S. icipe was observed to decrease with increased in temperature. The lowest developmental threshold temperatures estimated using linear regressions was 14.3, 12.67 and 19.12˚C and the thermal constants for development were 185.2, 1111.1- and 40.7-degree days (DD) for egg, nymph and pre-adult stages, respectively. The highest total fecundity (3416 individuals/female/generation), intrinsic rate of natural increase (0.075 days), net reproductive rate (1330.8 female/female/generation) and shortest doubling time (9.2 days) was recorded at 30˚C. The regions predicted to be suitable by the model suggest that S. icipe is tolerant to a wider range of climatic conditions. Our findings provide for the first-time important information on the impact of temperature on the biology, establishment and spread of S. icipe across the Africa continent. The prospect of edible S. icipe production to become a new sector in food and feed industry is discussed. ; Danish International Development Agency ; Netherlands Organisation for Scientific Research ; Federal Ministry for Economic Cooperation and Development, Germany ; International Development Research Centre ; Australian Centre for International Agricultural Research ; Department for International Development, United Kingdom ; Swedish International Development Cooperation Agency ; Swiss Agency for Development and Cooperation ; Government of Kenya ; Peer Review
