  • Evidence Brief: Foraged Mushroom Consumption in Ontario  Wild Mushrooms Are Found in Ontario’S Farmers’ Markets
    EVIDENCE BRIEF Foraged Mushroom Consumption in Ontario November 2019 Key Messages Wild mushrooms are widespread in Ontario, and are harvested by individual hobbyists and commercial enterprises for public consumption. Many species are poisonous. Health effects of such species can range from mild to severe, including death. However, serious poisonings are rare. There are no simple tests to determine if a mushroom is poisonous. Safe consumption of wild mushrooms and other wild foods requires they be correctly identified by knowledgeable harvesters. Over a thousand calls were made to the Ontario Poison Centre (OPC) over a recent 5-year period that were mushroom-related, with at least 90 cases resulting in hospital admission. There are no reported cases of poisoning linked to commercial foraging. However, currently there is no mechanism for licensing or accrediting wild mushroom foragers. Evidence Brief: Foraged Mushroom Consumption in Ontario Wild mushrooms are found in Ontario’s farmers’ markets. Certain farmers’ market food vendors are exempt from the Food Premises Regulation. However, assessments and inspections may be carried out to ensure compliance with the Health Protection and Promotion Act. Issue and Research Question Foraging of wild mushrooms occurs in diverse communities, including some within Ontario. 1-3 Foraged mushrooms may be sold in farmers’ markets, grocery stores, health food stores, restaurants, and online. There are reported cases of adverse health outcomes from consuming foraged mushrooms.1 Public health units in Ontario have requested advice from Public Health Ontario in response to concerns of potential adverse health effects from consumption of wild foraged mushrooms being sold in their regions.

Neonectria has been divided into informal groups on the basis of combined morphology of anamorph and teleomorph. Previously, Cylindrocarpon was divided into four groups defined by presence or absence of microconidia and chlamydospores. Molecular phylogenetic analyses have indicated that Neonectria sensu stricto and Cylindrocarpon sensu stricto are phylogenetically congeneric. In addition, morphological and molecular data accumulated over several years have indicated that Neonectria sensu lato and Cylindrocarpon sensu lato do not form a monophyletic group and that the respective informal groups may represent distinct genera. In the present work, a multilocus analysis (act, ITS, LSU, rpb1, tef1, tub) was applied to representatives of the informal groups to determine their level of phylogenetic support as a first step towards taxonomic revision of Neonectria sensu lato. Results show five distinct highly supported clades that correspond to some extent with the informal Neonectria and Cylindrocarpon groups that are here recognised as genera: (1) N.

  • GROCERY CARRY BAG SANITATION “A Microbiological Study Of
    GROCERY CARRY BAG SANITATION “A Microbiological Study of Reusable Bags and `First or single-use’ Plastic Bags” May 20th, 2009 The use of reusable food containers and carry devices for groceries is an important, to date overlooked piece in the study of the safety of the food supply in Canada. There has been little to no testing to investigate the risk reusables pose or do not pose to public health, yet increasingly reusables are being advanced as a viable substitute for first-use or single use packaging/ containers. The food service sector has been particularly concerned about the use of reusables. Research conducted last fall on a sample of reusables during the City of Toronto in-store packaging reduction program sparked even more concern by industry about potential public health risks. The Environment and Plastics Industry Council (EPIC) accordingly agreed to fund this independent piece of research in response to these public health concerns. The position of the plastics industry is clear. The industry strongly supports reduction and reuse, and recognizes use of reusables as good environmental practice, but it does not want to see these initiatives inadvertently compromise public health and safety. The industry believes that appropriate independent research and investigation must be pursued. Testing Laboratories Three independent testing laboratories were involved in this research study in order to provide broad and balanced testing and evaluation of the results. Two labs executed the testing – Guelph Chemical Laboratories (GCL) and Bodycote Testing Group of Montreal; and a third provided oversight and evaluative commentary of the results -- Toronto-based Sporometrics, the foremost experts in many aspects of fungal and environmental bacterial testing in Canada.

Mycosphere 1, 53–63. Baipadisphaeria spathulospora gen. et sp. nov., a freshwater ascomycete is characterized by black immersed ascomata, unbranched, septate paraphyses, unitunicate, clavate to ovoid asci, lacking an apical structure, and fusiform to almost cylindrical, straight or curved, hyaline to pale brown, unicellular, and smooth-walled ascospores. No anamorph was observed. The species is described from submerged decaying leaves of the peat swamp palm Licuala longicalycata. Phylogenetic analyses based on combined small and large subunit ribosomal DNA sequences showed that it belongs in Nectriaceae (Hypocreales, Hypocreomycetidae, Ascomycota). Baipadisphaeria spathulospora constitutes a sister taxon with weak support to Leuconectria clusiae in all analyses. Based
