Seafood local

The native people of the regions of Peru and Ecuador discovered that combining local seafood with citrus juices produced a cooked fish, called a seviche, that was firm and opaque. Why are lemon juices or lime juices used to marinate fish in the preparation of seviche ... 

Discharge water and emission from facilities that make americium smoke detectors or gauges or produce plutonium for nuclear weapons may contain americium. These operations are strictly regulated, but you can check local health advisories before consuming fish or other seafood from these waters. Nuclear reactors are not expected to discharge measurable amounts of americium. 

Even a single HAB episode can be extremely costly. In Maryland in 1997, reported eases of human disease associated with exposure to water containing Pfiesteria piscicida cost the seafood industry alone an estimated 46 million in lost revenue (Anderson et al., 2000). Lewis (1986) found that CFP in the South Paeifie depressed both the local and export fishing industries, affected tourism, and indirectly affected human health (because people avoided eating fresh fish). 

Local regulations controlling the harvest and sales of seafood may be more specific. For example, based on ciguatera testing in the 1980s, Dade County, Florida, has completely banned the sale of barracuda within the county (Lawrence et al., 1980). 

In recent years, strong evidence of an increase in the magnitude, duration, and geographical distribution of food-borne illnesses caused by seafood toxins has been presented. The effect can be seen in the form of impediments to the development, growth, and stability of the local and commercial seafood industries in various areas of the world—most noticeably throughout the tropics where an abundant, accessible seafood resource resides. 

Table 7.12 summarizes the level of POPs contamination in eight main locally consumed food groups in 2003. With the exception of DDT and HCB, POPs pesticides were not detected in most food groups. DDT was found in cereals, fruits, dairy products and seafoods, while HCB was detected in cereals only. PCBs was not detected in fruits, dairy products, meats or poultry, but found in seafood items at a mean concentration of 4.07 pg g-1 food. Measurable levels of dioxins/furans were found in cereals, dairy products, eggs, seafoods, meats and poultry, with mean dioxin/furan levels ranging from 0.001 (meats) to 0.285 (seafoods) pg TEQ g-1 food. Dioxins/furans were not analyzed in vegetable and fruit items sampled in 2003. 

The health risk to local residents associated specifically with exposure to POPs contamination in the local marine environment was assessed by (a) comparing the levels of POPs contamination in marine fish and shellfish sampled in the local waters with relevant Food Safety Standards/Action Levels and (b) evaluating the non-carcinogenic and carcinogenic risks of individual POPs intake via consumption of locally caught seafood and incidental ingestion of seawater during recreational activities. 

Results of assessment of carcinogenic risks associated with exposure of local residents to POPs contamination in the local marine environment are presented in Table 7.22. The calculated cancer risks of POPs all fell well within the 1 x 10 4-1 x 10-6 range, indicating there was no unacceptable cancer risk of toxicological concern associated specifically with a lifetime exposure of local residents to the current level of POPs contamination in the local marine environment via dietary intake of locally caught seafood (marine fish and shellfish) and incidental ingestion of seawater during recreational activities. 

Live red swamp crayfish fProcambarus clarkii) and pasteurized blue crab (Callinectes sapidus) meat samples were purchased from local seafood retailers.

Goiter is the human pathology of hyperplasia of the thyroid gland induced by the deficiency of dietary iodine. The disease is localized in those regions where soils are low in iodine or where seafood is not consumed. Fortification of fable salt with sodium iodide, where applied, has practically eradicated this disease. Unfortunately, many regions of the world do not practice this public health policy. 

The Japanese diet contains a lot of fish, and the local fishermen and their families would eat more fish than most. The fishermen were catching fish and seafood in the waters of Minamata Bay, waters which proved to be heavily contaminated with methyl mercury. In 1956 the first case of what became known as Minamata disease was reported and then other people started to present themselves to doctors and at hospitals with various symptoms such as muscular incoordination and difficulties in speech. Their pet cats, which were also eating the fish, suffered similar symptoms. 

MMHg poisoning is known as Minamata disease. Unfortunately, and between 1950 and 1975, major industrially related mass poisonings, severe debilitation, and many deaths occurred in Minamata and Niigata, Japan and in Iraq. The Japanese poisonings resulted from consumption of locally caught fish and seafood that had been... 

Several factors influence the level of fluorides in food. These include the locality in which the food is grown, the amount of fertilizer and pesticides applied, the type of processing the food receives, and whether fluoridated water is used in food preparation. Foods characteristically high in fluoride content are certain types of seafood (1.9-28.5mgkg ), especially those types in which the bones are consumed, bone products such as bone meal and gelatin, tea, and baby formula processed with fluoridated water.

Tamashiro et al. (1986) compared the death rates among residents of the Fukuro and Tsukinoma districts with those of age-matched residents of Minamata City. Residents of the two districts were assiuned to have a higher intake of local seafood and higher Hg exposure than residents... 

However, consumption data vary considerably between regions, depending on local conditions and eating habits. Whereas the consumption of seafood per capita in 2003 was 160 kg in the Maldives, 91 kg in Island, 75 kg in Japan, 59 kg in Portugal, and 51 kg in Norway, the intake was about 21 kg in the United States, 16 kg in Germany, 5 kg in China, and only 4 kg in Hungary (Laurenti, 2007). 

Fig. 22.6 The giant barnacle Austromegabalanus psittacus from Chile, (a) Small individuals are often found on the thick shells of adults, (b) Where benthic populations are available this species is sold in local seafood markets, (c) Only large and singly grown individuals find their way to the dinner plate. Giant barnacles readily grow on submerged structures but their culture remains as yet largely unexplored, mostly due to unpredictable larval settlement and costly larval culture.
