Freshwater Paralytic Shellfish Poisoning Toxins and other Cyanobacterial Neurotoxins in New York Lakes by Zacharias J. Smith A dissertation submitted in partial fulfillment of the requirements for the Doctor of Philosophy Degree State University of New York College of Environmental Science and Forestry Syracuse, New York December 2019 Department of Chemistry Approved by: Gregory Boyer, Major Professor Roxanne Razavi, Chair, Examining Committee Avik Chatterjee, Department Chair S. Scott Shannon, Dean, The Graduate School i © Copyright Zacharias J. Smith All rights reserved ii Acknowledgments I gratefully acknowledge the support of Dr. Gregory Boyer throughout the completion of my degree, where without his technical and academic support this achievement would not have been possible. I would also like to acknowledge my steering committee members, Dr. Dave Kieber and Dr. John Hassett for their guidance throughout the process. I would like to extend further thanks to Dr. Kimberly Schulz for her assistance with statistical analyses and for her time attending as an additional steering committee member and as an examiner. Thank you as well to Dr. Gord Paterson for his guidance and for acting as a member of my examination committee. I would like to thank my lab mates for their help and friendship over the years. Exceptional thanks goes out to Bofan Wei for his help sampling at Butterfield Lake and for helping bring that project to completion. Additionally, I would like thank Bofan for his friendship and loyalty over the years, especially through challenging times. I would further like to thank Kristen Slodysko, a stranger from Seattle who somehow knew a friend-of-a-friend and who ended up on the other side of the United State in the same laboratory but who also became an amazing friend! I want to thank Kristen for all of the times we got coffee together and had a good time hanging out. Additionally, Kristen was responsible for bringing out my interest and knowledge of statistics, which turned out to be critical. Although our discussions about statistics were complex and sometimes frustrating, great thanks goes out to her for taking the time to help me get started in this area. I would like to thank Adam Marshall for his time with me early on in the process of earning my doctorate. Not only was and is Adam a great friend, but he helped me push through the several highly stressful first-years of my doctorate. His friendship is greatly treasured. Finally, I would like to thank my parents, Jonathan Smith and Sara Jessie Tarr. Without their loving support and compassion, I would never have made it to graduate school, let alone complete a doctorate. I could not have asked for any more from them. They have offered me support, love, guidance, care, tenderness, appreciation, and a constant source of companionship and conversation. They have made me a better person, a better scientist, and I could never dream of having more. iii Table of Contents List of Tables ........................................................................................................................................................... xv List of Figures ........................................................................................................................................................ xvii List of Supplementary Information ..................................................................................................................... xx Abstract ............................................................................................................................................................... xxviii List of Abbreviations and Symbols .................................................................................................................. xxvi Introduction ................................................................................................................................................................ 1 The Nature of the Problem .................................................................................................................................... 1 1.1 Harmful Cyanobacteria and Neurotoxins ................................................................................................. 1 1.2 Hypothesis and Objectives .......................................................................................................................... 4 1.3.

  • Allergic and Toxic Reactions to Seafood
    Allergic and toxic reactions to seafood ASCIA EDUCATION RESOURCES (AER) PATIENT INFORMATION Seafood allergy occurs most commonly where seafood is an important part of the diet, such as Asia and Scandinavia. It is more common in adults than children. Seafood allergy usually remains a life long problem. Some conditions caused by toxins or parasites in seafood can resemble allergic reactions to seafood. Seafood allergy is not rare While estimates vary from country to country, approximately 1% of the population is estimated to suffer from seafood allergy, which is more common in teenage and adult life than very early childhood. An estimated 20% will grow out of their allergy with time. Symptoms of seafood allergy are usually obvious Many allergic reactions to seafood are mild and cause hives (urticaria), swelling (angioedema) and/or gut reactions (vomiting, diarrhoea). The most dangerous symptoms are breathing difficulties or collapse [a drop in blood pressure (shock)], either of which can be life threatening. This is known as anaphylaxis, which is the most severe type of allergic reaction. Occasionally, breathing difficulties may occur from inhaling fumes when seafood is being cooked, and in seafood processing factories. Children with a history of asthma may be more likely to have severe allergic reactions to seafood. There are many varieties of seafood The major groups of seafood that can trigger allergic reactions are: • VERTEBRATES Fish including salmon, cod, mackerel, sardines, herring, anchovies, tuna, trout, haddock, John Dory, eels, rays. • INVERTEBTRATES (SHELLFISH) Crustaceans including prawns/shrimps, lobster, crab, crayfish, yabbies. Molluscs including oysters, mussels, clams, octopus, squid, calamari, abalone, sea slugs.

  • (Slide 1) Lesson 3: Seafood-Borne Illnesses and Risks from Eating
    Introductory Slide (slide 1) Lesson 3: Seafood-borne Illnesses and Risks from Eating Seafood (slide 2) Lesson 3 Goals (slide 3) The goal of lesson 3 is to gain a better understanding of the potential health risks of eating seafood. Lesson 3 covers a broad range of topics. Health risks associated specifically with seafood consumption include bacterial illness associated with eating raw seafood, particularly raw molluscan shellfish, natural marine toxins, and mercury contamination. Risks associated with seafood as well as other foods include microorganisms, allergens, and environmental contaminants (e.g., PCBs). A section on carotenoid pigments (“color added”) explains the use of these essential nutrients in fish feed for particular species. Dyes are not used by the seafood industry and color is not added to fish—a common misperception among the public. The lesson concludes with a discussion on seafood safety inspection, country of origin labeling (COOL) requirements, and a summary. • Lesson 3 Objectives (slide 4) The objectives of lesson 3 are to increase your knowledge of the potential health risks of seafood consumption, to provide context about the potential risks, and to inform you about seafood safety inspection programs and country of origin labeling for seafood required by U.S. law. Before we begin, I would like you to take a few minutes to complete the pretest. Instructor: Pass out lesson 3 pretest. Foodborne Illnesses (slide 5) Although many people are complacent about foodborne illnesses (old risk, known to science, natural, usually not fatal, and perceived as controllable), the risk is serious. The Centers for Disease Control and Prevention (CDC) estimates 48 million people suffer from foodborne illnesses annually, resulting in about 128,000 hospitalizations and 3,000 deaths.

  • Small Scale Clam Farming in Washington
    S m a l l - S c a l e CLAM Farming For PleaSure and ProFit in WaShington According to one Native American tale, the first humans arrived in the Pacific Northwest by stepping out of a clam shell. Since those ancient times, clams have had central roles in shaping the cultures and economies of the Pacific Northwest. For many shoreline property owners or leaseholders in Washington, clam farming is an enjoyable and sometimes profitable way to remain connected with the rich aquacultural legacy of the state. It is also a good way for them to become more aware of coastal processes such as sedimentation and erosion and to be vigilant for Spartina cordgrass, European green crab and other unintentionally introduced marine organisms. Two clam species — native littleneck clams and Manila clams — are routinely farmed in Washington. This publication introduces shoreline property owners and leaseholders to these two species and describes methods for growing clams for consumption. 1 2 IntroducIng two PoPular clams Three clam species — native littleneck clams (Protothaca staminea), Manila clams (Venerupis japonica) and geoduck clams (Panope abrupta) — are routinely farmed in Washington. Successful cultivation of geoduck clams entails different farming strategies and, as such, is not described in this introductory document. Native littleneck clams have been an important food On Washington beaches, Manila clams thrive in source of Northwest coastal Indian tribes. These clams protected bays and inlets on relatively stable have relatively thick shells that can attain a length of beaches with mixtures of gravel, sand, three inches. They can grow to a harvestable size in mud and shell.

Population and Public Health Division Ministry of Health and Long-Term Care March 2017 AT A GLANCE A Quick Response Guide to Botulism Botulism – The treatment of botulism is guided by clinical diagnosis The initial diagnosis of botulism should be based on a history of recent exposure, consistent clinical symptoms and elimination of other illnesses in the differential. Treatment should not wait for laboratory confirmation. All treatment and management decisions should be made based on clinical diagnosis. Initial Presentation and evaluation of signs and symptoms There are several clinically distinct forms of botulism. All forms produce the same neurological signs and symptoms of symmetrical cranial nerve palsies followed by descending, symmetric flaccid paralysis of voluntary muscles, which may progress to respiratory compromise and death. Additional symptoms (e.g., gastrointestinal signs in foodborne cases) may also be seen in some forms.

Abstract: Diarrheal shellfish toxins (DSTs) are among the most widely distributed phytotoxins, and are associated with diarrheal shellfish poisoning (DSP) events in human beings all over the world. Therefore, it is urgent and necessary to identify an effective method for toxin removal in bivalves. In this paper, we found that curcumin (CUR), a phytopolylphenol pigment, can inhibit the accumulation of DSTs (okadaic acid-eq) in the digestive gland of Perna viridis after Prorocentrum lima exposure. qPCR results demonstrated that CUR inhibited the induction of DSTs on the aryl hydrocarbon receptor (AhR), hormone receptor 96 (HR96) and CYP3A4 mRNA, indicating that the CUR-induced reduction in DSTs may be correlated with the inhibition of transcriptional induction of AhR, HR96 and CYP3A4. The histological examination showed that P. lima cells caused severe damage to the digestive gland of P. viridis, and the addition of curcumin effectively alleviated the damage induced by P. lima. In conclusion, our findings provide a potential method for the effective removal of toxins from DST-contaminated shellfish.

  • List of Bivalve Molluscs from British Columbia, Canada
    List of Bivalve Molluscs from British Columbia, Canada Compiled by Robert G. Forsyth Research Associate, Invertebrate Zoology, Royal BC Museum, 675 Belleville Street, Victoria, BC V8W 9W2; [email protected] Rick M. Harbo Research Associate, Invertebrate Zoology, Royal BC Museum, 675 Belleville Street, Victoria BC V8W 9W2; [email protected] Last revised: 11 October 2013 INTRODUCTION Classification rankings are constantly under debate and review. The higher classification utilized here follows Bieler et al. (2010). Another useful resource is the online World Register of Marine Species (WoRMS; Gofas 2013) where the traditional ranking of Pteriomorphia, Palaeoheterodonta and Heterodonta as subclasses is used. This list includes 237 bivalve species from marine and freshwater habitats of British Columbia, Canada. Marine species (206) are mostly derived from Coan et al. (2000) and Carlton (2007). Freshwater species (31) are from Clarke (1981). Common names of marine bivalves are from Coan et al. (2000), who adopted most names from Turgeon et al. (1998); common names of freshwater species are from Turgeon et al. (1998). Changes to names or additions to the fauna since these two publications are marked with footnotes. Marine groups are in black type, freshwater taxa are in blue. Introduced (non-indigenous) species are marked with an asterisk (*). Marine intertidal species (n=84) are noted with a dagger (†). Quayle (1960) published a BC Provincial Museum handbook, The Intertidal Bivalves of British Columbia. Harbo (1997; 2011) provided illustrations and descriptions of many of the bivalves found in British Columbia, including an identification guide for bivalve siphons and “shows”. Lamb & Hanby (2005) also illustrated many species.
