Ciguatera Food Poisoning in Europe”
“RISK CHARACTERIZATION OF CIGUATERA FOOD POISONING IN EUROPE” 71st Advisory Forum Meeting 03-04 April 2019 Bucharest, Rumania FRAMEWORK PARTNERSHIP AGREEMENT GP/EFSA/AFSCO/2015/03 RISK CHARACTERIZATION OF CIGUATERA FOOD POISONING IN EUROPE [email protected] What is the Ciguatera? • Ciguatoxin is produced by micro algae, or dinoflagellates, called Gambierdiscus spp. The toxins climb up the food chain until the contaminated fish are caught and served to people. • These toxins cause Ciguatera food poisoning (CFP) which is a complex syndrome: gastrointestinal, neurological and cardiovascular effects. CFP is primarily associated with the consumption of large predator fish that have accumulated the toxins by feeding on smaller contaminated coral reef fish. • At present, CFP is the most common type of marine biotoxins food poisoning worldwide with an estimated number of 10.000 to 50.000 people suffering from the disease annually. FRAMEWORK PARTNERSHIP AGREEMENT GP/EFSA/AFSCO/2015/03 RISK CHARACTERIZATION OF CIGUATERA FOOD POISONING IN EUROPE [email protected] Worldwide distribution of ciguatera Caribbean Ciguatoxin Pacific Ciguatoxin Red dots: ciguatera cases of poisoning. Yellow dots: presence of Gambierdiscus spp. FRAMEWORK PARTNERSHIP AGREEMENT GP/EFSA/AFSCO/2015/03 RISK CHARACTERIZATION OF CIGUATERA FOOD POISONING IN EUROPE [email protected] Background Ciguatera 2004 Gambierdiscus spp., responsible for ciguatera in the waters of the Canary Islands and Madeira microalgae, was detected. 2008 autochthonous ciguatera outbreaks in Spain (Canary Islands) and in Portugal (Madeira). Between 2008 and 2018 18 outbreaks (115 cases) recorded in Canary Islands Fish genus Seriola was involved in many of the outbreaks. These new findings suggest the microorganism is becoming an increasing risk for European countries. -

They are viewed as a suitable alternative to industrial fisheries, particularly when considering their social and economic importance in developing countries. Here, we show that the booming small-scale fishery sector in Senegal, in the context of increasing foreign demand, has induced the collapse of one of the most emblematic West African marine fish species, a large grouper Epinephelus aeneus , historically called ‘false cod’ by European fishers. The overexploitation of this species appears to be on account of the increasing effort sustained by a growing international demand and important subsidies, which resulted in a relative stability of the average economic yield per fishing trip and an incentive for continuing targeting this species to almost extinction. -

Olakolu Nigerian Institute for Oceanography and Marine Research, No 3 Wilmot Point Road, Bar-beach Bus-stop, Victoria Island, Lagos, Nigeria. Mrs H.O. Omogoriola Nigerian Institute for Oceanography and Marine Research, No 3 Wilmot Point Road, Bar-beach Bus-stop, Victoria Island, Lagos, Nigeria. EDITOR: Mrs Ajetomobi School of Agricultural Sciences Lagos State Polytechnic Ikorodu, Lagos 2 BIO 313 COURSE GUIDE Introduction Animal Ecology (313) is a first semester course. It is a two credit unit elective course which all students offering Bachelor of Science (BSc) in Biology can take. Animal ecology is an important area of study for scientists. It is the study of animals and how they related to each other as well as their environment. It can also be defined as the scientific study of interactions that determine the distribution and abundance of organisms. Since this is a course in animal ecology, we will focus on animals, which we will define fairly generally as organisms that can move around during some stages of their life and that must feed on other organisms or their products. There are various forms of animal ecology. This includes: • Behavioral ecology, the study of the behavior of the animals with relation to their environment and others • Population ecology, the study of the effects on the population of these animals • Marine ecology is the scientific study of marine-life habitat, populations, and interactions among organisms and the surrounding environment including their abiotic (non-living physical and chemical factors that affect the ability of organisms to survive and reproduce) and biotic factors (living things or the materials that directly or indirectly affect an organism in its environment). -
Sex-Ratio, Maturation and Spawning of the Indian Ilisha, Ilisha Melastoma (Clupeiformes: Pristigasteridae) in Coastal Waters of Pakistan (Northern Arabian Sea)
Indian Journal of Geo-Marine Sciences Vol. 40(4), August 2011, pp. 516-521 Sex-ratio, maturation and spawning of the Indian ilisha, ilisha melastoma (clupeiformes: pristigasteridae) in coastal waters of Pakistan (northern Arabian Sea) Khalid Mahmood , Zarrien Ayub* & Ghazala Siddiqui Centre of Excellence in Marine Biology, University of Karachi, Karachi-75270, Pakistan *[E-mail address: [email protected]] Received 22 March 2010; revised 5 December 2010 Present study showed that the over-all sex-ratio deviated in favour of females in Ilisha melastoma. However, the sex- ratio was approximately 1:1 in certain months while in others it was in favor of females. Similarly the sex-ratio deviated from 1:1 ratio in different size-classes. Minimum size at which the specimens of I. melastoma get matured is 14.9 cm in total length (11.5 cm in SL). Four maturation stages of ovaries, namely, immature, ripening, ripe and spent/recovering were recognized in I. melastoma. Two peaks of spawning were observed in this species, the major peak was from February to May and the minor peak appeared in August to November. [Keywords: Maturation, spawning, Indian ilisha, Pakistan] Introduction during the period March 2004 to February 2005 and a Species of the genus Ilisha are distributed in the total of 725 specimens of I. melastoma were Indo-Pacific region, i.e., Japan, China, Hong Kong, examined. Total length (cm) and weight (g) of each Singapore, Java, Borneo, Sumatra, Burma, India, fish was recorded. Fish was dissected from the Pakistan, Persian Gulf and Africa. According to abdominal region and the sex and gonadal maturity of Whitehead1 genus Ilisha have a circumtropical fish was determined by visual examination of gonads distribution in estuaries and coastal waters, with one (Table 3). -

Dengue Fever in Senegal 6 - 7 Ongoing Events Ebola Virus Disease in the Democratic Republic of the Congo Humanitarian Crisis in Cameroon
Overview Contents This Weekly Bulletin focuses on selected acute public health emergencies occurring in the WHO African Region. The WHO Health Emergencies Programme is currently monitoring 58 events in the region. This week’s edition covers key new and ongoing events, including: 2 Overview Hepatitis E in Central African Republic 3 - 5 New events Monkeypox in Central African Republic Dengue fever in Senegal 6 - 7 Ongoing events Ebola virus disease in the Democratic Republic of the Congo Humanitarian crisis in Cameroon. 8 Summary of major issues challenges and For each of these events, a brief description, followed by public health proposed actions measures implemented and an interpretation of the situation is provided. 9 All events currently A table is provided at the end of the bulletin with information on all new and being monitored ongoing public health events currently being monitored in the region, as well as events that have recently been closed. Major issues and challenges include: The Ebola virus disease (EVD) outbreak in the Democratic Republic of the Congo has reached a critical juncture, marked by a precarious security situation, persistence of pockets of community resistance/ mistrust and expanding geographical spread of the disease. During the reporting week, there was an incident involving a response team performing burial activity in Butembo. This came barely days following a widespread community strike (“ville morte”) in Beni and several towns, and an earlier armed attack in Beni. These incidents severely disrupted most outbreak control interventions. Meanwhile, EVD cases have been confirmed in new areas with worse insecurity and in close proximity to the border with Uganda. -
(Etp) Species in West Africa
Issue Brief AN OVERVIEW OF THE ILLEGAL HARVEST OF AQUATIC ENDANGERED, THREATENED OR PROTECTED (ETP) SPECIES IN WEST AFRICA AQUATIC WILDMEAT: THE PLIGHT OF THREATENENED AQUATIC SPECIES Throughout West Africa, declining fisheries resources and rising human populations have accelerated the displacement WHAT IS AQUATIC BUSHMEAT? of many communities from their traditional food sources. This Aquatic wild meat, sometimes referred to in turn is driving new forms of aquatic meat consumption, as as aquatic bushmeat, is defined as the meat well as the rise of illegal local and international trade aimed at of aquatic species harvested and used by revenue generation. As a consequence, this aquatic harvest is humans as food resources, medicines and/ now seriously impacting large aquatic mammal, reptile and avian or cultural/ traditional items (e.g. religious biodiversity in the region. This aquatic harvest is ‘falling through items). Aquatic wildmeat includes marine the cracks’ between environment and fisheries Ministries, mammals such as manatees, cetaceans and agencies and international processes. hippopotamus, reptiles such as crocodiles and marine turtles, fish (sharks and rays), and In West Africa, as worldwide, aquatic species have been aquatic birds (herons, pelicans and storks harvested for decades by local populations. Some of the most amongst others). famous human uses are (1) the trade of the hawksbill marine turtle’ shell (bekko) through Japanese networks, (2) the consumption of manatee’s or marine turtle’s meat by coastal populations and (3) the harvest of sharks for their fins for the Asian market (Miliken & Tokunaga 1987; Groombridge & Luxmoore 1989; Diop & Dossa 2011). A WIDE VARIETY OF AQUATIC SPECIES ARE THREATENED Over time, aquatic bushmeat consumption, increasing human populations and poorly enforced measures punishing the use or trade of these aquatic species, could threaten the survival of many aquatic species. -
