Seafoods

In frozen prawns or shrimp the concentration of L-ascorbic acid is used according to GMP, but is limited to such a level so as not to affect the product negatively, or to disturb its compliance with legal requirements (Van Heerden, 2003).

Seed-Meal Concentrates and Isolates. Seed-meal protein products include flours, concentrates, and isolates, particularly soy protein products. These can be used as extenders for meat, seafood, poultry, eggs, or cheese (see Soybeans and other oilseeds). Detailed information on soybean and other seed-meal production processes is available (13,14,18).

Seafood Toxins. Vktually scores of fish and shellfish species have been reported to have toxic manifestations. Most of these toxicities have been shown to be microbiological ki origin. There are a few, however, that are natural components of seafoods. 

Iodine. Of the 10—20 mg of iodine in the adult body, 70—80 wt % is in the thyroid gland (see Thyroid and antithyroid preparations). The essentiahty of iodine, present in all tissues, depends solely on utilisation by the thyroid gland to produce thyroxine [51-48-9] and related compounds. Well-known consequences of faulty thyroid function are hypothyroidism, hyperthyroidism, and goiter. Dietary iodine is obtained from eating seafoods and kelp and from using iodized salt. 

Seafood. Sorbates are used to extend the shelf life of many seafood products, both fresh and processed (103,104). For smoked or dried fish, an instantaneous dip in 5 wt % potassium sorbate or a 10-minute dip in 1.0 wt % potassium sorbate prior to drying or smoking inhibits the development of yeast and mold (105,106). For fresh fish, sorbates can be incorporated at approximately 0.5 wt % into the ice, refrigerated seawater, or ice-water slush in... 

Like plants, marine and fresh water organisms vary significantly in their response to zinc. The range of concentration among species is relatively narrow, except for oysters, which tend to accumulate zinc to very high levels. The zinc content of most seafoods ranges from 3—30 ppm. Oysters contain from 100—2000 ppm. 

Antimony may enter the human body through the consumption of meats, vegetables, and seafood which all contain about 0.2—1.1 ppb antimony. Disposal of Antimony. Antimony and its compounds have been designated as priority pollutants by the EPA (35). As a result users, transporters, generators, and processors of antimony-containing material must comply with regulations of the Eederal Resource Conservative and Recovery Act (RCRA). 

Seafood. Citric acid is used in combination with other preservatives/antioxidants to lower the pH to retard microbial growth, which can lead to spoilage, formation of off-flavors, and colors on fish and other seafood products. 

The dissolved-air flotation process is most commonly used for sewage and potable water treatment. It is also gaining popularity for the treatment of slaughterhouse, poultry processing, seafood processing, soap, and food processing wastes (Zoubulis et. al., 1991).

Nutritional deficiency of vitamin B12—Eat a balanced diet diat includes seafood, eggs, meals, and dairy products. 

Pernicious anemia—Lifetime therapy is necessary. Eat a balanced diet tiiat includes seafood, eggs, meats, and dairy products. Avoid contact with infections, and report any signs of infection to the primary health care provider immediately because an increase in dosage may be necessary. 

Before a patient starts therapy with an antithyroid drug, die nurse obtains a history of the symptoms of hyperthyroidism. It is important to include vital signs, weight, and a notation regarding the outward symptoms of die hyperthyroidism (see Table 51-1) in the physical assessment. If die patient is prescribed an iodine solution, it is essential that die nurse take a careful allergy history, particularly to iodine or seafood (which contains iodine). 

The federal government has set standards and guidelines to protect people from the possible adverse health effects of endosulfan in drinking water and food. EPA recommends that the amount of endosulfan in lakes, rivers, and streams should not be more than 74 micrograms per liter (pg/L) or 74 parts per billion (74 ppb). This should prevent any harmful health effects from occurring in people who drink the water or eat fish or seafood that live in the water. FDA allows no more than 24 parts per million (24 ppm) of endosulfan on dried tea, and EPA allows no more than 0.1 to 2 ppm endosulfan on other raw agricultural products.
