S U M M A R YCryptosporidium is increasingly recognized as one of the major causes of moderate to severe diarrhoea in developing countries. With treatment options limited, control relies on knowledge of the biology and transmission of the members of the genus responsible for disease. Currently, 26 species are recognized as valid on the basis of morphological, biological and molecular data. Of the nearly 20 Cryptosporidium species and genotypes that have been reported in humans, Cryptosporidium hominis and Cryptosporidium parvum are responsible for the majority of infections. Livestock, particularly cattle, are one of the most important reservoirs of zoonotic infections. Domesticated and wild animals can each be infected with several Cryptosporidium species or genotypes that have only a narrow host range and therefore have no major public health significance. Recent advances in next-generation sequencing techniques will significantly improve our understanding of the taxonomy and transmission of Cryptosporidium species, and the investigation of outbreaks and monitoring of emerging and virulent subtypes. Important research gaps remain including a lack of subtyping tools for many Cryptosporidium species of public and veterinary health importance, and poor understanding of the genetic determinants of host specificity of Cryptosporidium species and impact of climate change on the transmission of Cryptosporidium.

“…Analysis indicates that subtypes from humans and wildlife are genetically similar and zoonotic transmission might play a potential role in human infections (Guo et al., 2015). The skunk and mink genotypes have also been reported in a few human cases of cryptosporidiosis (Robinson et al., 2008, Chalmers et al., 2009, Rengifo-Herrera et al., 2011, Elwin et al., 2012, Ng-Hublin et al., 2013, Ebner et al., 2015). …”

Cryptosporidium is an enteric parasite that is transmitted via the faecal–oral route, water and food. Humans, wildlife and domestic livestock all potentially contribute Cryptosporidium to surface waters. Human encroachment into natural ecosystems has led to an increase in interactions between humans, domestic animals and wildlife populations. Increasing numbers of zoonotic diseases and spill over/back of zoonotic pathogens is a consequence of this anthropogenic disturbance. Drinking water catchments and water reservoir areas have been at the front line of this conflict as they can be easily contaminated by zoonotic waterborne pathogens. Therefore, the epidemiology of zoonotic species of Cryptosporidium in free-ranging and captive wildlife is of increasing importance. This review focuses on zoonotic Cryptosporidium species reported in global wildlife populations to date, and highlights their significance for public health and the water industry.

“…Data linking presence in seawater to food-borne illness Very large numbers of cryptosporidial oocysts can occur in the faeces of infected animals (up to 10 9 /g) and inputs into marine environments can occur via freshwater (Fayer et al, 2004) from human sewage and bathers (both C. parvum and C. hominis; (Graczyk et al, 2007), from livestock, domestic and wild animals including rodents (C. parvum). Cryptosporidium has been detected in marine mammals (Hughes-Hanks et al, 2005;Rengifo-Herrera et al, 2010) although their infectiousness to humans is poorly understood, however C.hominis has been detected in a dougon in Australia (Morgan et al, 2000). Outbreaks associated with contaminated drinking water have been reported world-wide (Fayer et al, 2004;LeChevallier and Moser, 1995).…”

Document VersionPublisher's PDF, also known as Version of record SUMMARYFollowing a request from the European Commission, the Panel on Biological Hazards (BIOHAZ) and the Panel on Contaminants in the Food Chain (CONTAM) were asked deliver a scientific opinion on the minimum hygiene criteria to be applied to clean seawater and on the public health risks and hygiene criteria for bottled seawater intended for domestic use.European food legislation establishes the conditions for the use of clean seawater in land-based fishery establishments. Currently, the use of clean seawater is allowed for use in on-shore establishments, auctions and fish markets, for the handling and washing of fishery products, the production of ice for chilling fishery products and for rapid cooling of crustaceans and molluscs after their cooking. Nonetheless, there are no harmonised rules in the European legislation with regard to the sanitary criteria that clean seawater should respect.Based on incidents of food and waterborne infection, the properties and the distribution of the agents, microbiological hazards (including viruses, bacteria and parasites) have been associated with seawater. Poor quality sea water may consequently have a severe impact on public health through contamination which may occur during food processes. The hazards are associated either with bacteria, which are part of the natural marine biota (in particular Vibrio spp.), or pathogenic microbes derived from animal or human faecal contamination, which is most often of terrestrial origin. Nonetheless, there is currently not sufficient data on microbiological hazards to estimate the public health risks associated with the uses in on-land establishments for handling and washing fishery products, for the production of ice used for chilling, for rapid cooling of crustaceans and molluscs after cooking, and for bottled seawater. In the absence of data to propose risk-based criteria, hazard-based criteria are proposed instead. These should provide the same level of health protection as achieved by other food business operators through the use of potable water.It is underlined that coastal sources, used for abstraction of seawater in land-based establishments, cannot be guaranteed to be free from pathogens from the marine biota or from faecal contamination, and cannot be classified as a pristine source.Sanitary surveys provide information to optimize the site of abstraction in order to control sources of faecal pollution and chemical contamination. Additional safeguards will be needed to reduce contamination from endogenous marine flora (including pathogenic Vibrio spp. and C. botulinum). Since these hazards are associated with temperature and salinity (Vibrio spp.) as well as sediments (C. botulinum), abstracting seawater with high salinity (especially in waters of temperatures below 20 ºC), and free from particulate material will improve safety of seawater prior to treatment. The comprehensiveness of the sanitary survey, the stringency of microbiological criteria and the nee...
