“…Contamination was likely present in UW because of the vulnerability of these resources and the fact that these samples were chosen by local public health officials because of frequent pathogen recovery (coliform) or high turbidity levels. This frequency in the detection of major parasites has already been reported (Slifko et al 2000). Giardia and Cryptosporidium are more ubiquitous in nature because of their excretion by a wide range of hosts, while Toxoplasma oocysts are only excreted by felids.…”

“…This is especially the case with the protozoan parasites, such as Giardia duodenalis, Cryptosporidium sp., and Toxoplasma gondii, and the helminth Toxocara sp. (Slifko et al, 2000). Waterborne transmission plays a major role in the transmission of these parasites to the population, at large.…”

“…Waterborne transmission plays a major role in the transmission of these parasites to the population, at large. Several outbreaks of giardiasis, cryptosporidiosis, toxoplasmosis, and toxocarosis, to one degree or another, are attributed to water and food transmission via (oo)cysts or ova of these parasites (Yilmaz and Hopkins, 1972;Benenson et al, 1982;Mac Kenzie et al, 1994;Bowie et al, 1997;Cotte et al, 1999;Slifko et al, 2000). In such cases, human infection can occur either by direct consumption or by the use of contaminated water in food processing or preparation.…”

Beaches worldwide provide recreational opportunities to hundreds of millions of people and serve as important components of coastal economies. Beach water is often monitored for microbiological quality to detect the presence of indicators of human sewage contamination so as to prevent public health outbreaks associated with water contact. However, growing evidence suggests that beach sand can harbor microbes harmful to human health, often in concentrations greater than the beach water. Currently, there are no standards for monitoring, sampling, analyzing, or managing beach sand quality. In addition to indicator microbes, growing evidence has identified pathogenic bacteria, viruses, and fungi in a variety of beach sands worldwide. The public health threat associated with these populations through direct and indirect contact is unknown because so little research has been conducted relating to health outcomes associated with sand quality. In this manuscript, we present the consensus findings of a workshop of experts convened in Lisbon, Portugal to discuss the current state of knowledge on beach sand microbiological quality and to develop suggestions for standardizing the evaluation of sand at coastal beaches. The expert group at the "Microareias 2012" workshop recommends that 1) beach sand should be screened for a variety of pathogens harmful to human health, and sand monitoring should then be initiated alongside regular water monitoring; 2) sampling and analysis protocols should be standardized to allow proper comparisons among beach locations; and 3) further studies are needed to estimate human health risk with exposure to contaminated beach sand. Much of the manuscript is focused on research specific to Portugal, but similar results have been found elsewhere, and the findings have worldwide implications.

“…Studies by Slifko et al (2000acited in Orlandi et al, 2002Slifko et al, 2000b) demonstrated that more than 99% of Cryptosporidium parvum oocysts were inactivated following >60 sec HHP treatment. The use of HHP on fish for inactivation of helminths is currently investigated.…”

Traditional fish products (TFPs) are usually produced by applying old preserving methods such as salting, fermenting, drying and smoking. These products also greatly varies amongst the countries as well as within the same country by using many different applications such as differences in additives, percentage of salt or vinegar and maturing temperatures. Moreover, modifications in these techniques are also known due to food safety issues and changes in customer preference of new generation. Although such processing/preserving methods have been known as old techniques for many years, they have still wide acceptance around the world because of their specific taste and aroma.Due to their specific characteristics for varying many types, they have both advantages and disadvantages relating to seafood health risks that makes them difficult to identify, establish effective preventive and/or monitoring procedures. In this paper, the most common seafood health hazards were evaluated under five main traditional fish processing methods. The preventive measures were discussed along with effective monitoring in Hazard Analysis Critical Control Points (HACCP) system application for specific products by reviewing current literature and regulations under this subject. Seafood safety hazards were evaluated under two sections as 'raw material receiving and storage stage before processing including other ingredients and packaging materials', and 'processing and storage stage'.Although it is easy to prevent certain health hazards at the receiving stage, some of them have to be monitored from harvesting along with processing until consumption. The most common seafood health hazards, which threathens TFPs, were mainly found as histamine, parasites, Listeria monocytogenes and Clostridium botulinum, and they were discussed under each process type. In the scope of this study, preventive measures and further studies related to major health hazards are suggested under each specific TFPs.
