“…Since tropomyosin is heat-stable, both raw and cooked crab are possible sources for aerosolised tropomyosin (Jeebhay et al 2001;Lopata and Jeebhay 2013). Antibody reactivity of crustacean tropomyosin can also increase after heating, a possible result of protein denaturation and exposure of new epitopes, aggregation and chemical modifications Abramovitch et al 2013). A study involving snow crab processing found more aerosolised allergen when workers were handling cooked crab than raw which is in line with the results of the present study.…”

Red king crab and snow crab have both become important species for the Norwegian seafood industry. Since the first commercial harvest of red king crab in 2002 and of snow crab in 2012, the Norwegian seafood industry has developed new technology and knowledge for handling these species. This includes new fishing gear, conditions for live storage and processing, handling of byproducts, and entrance into new markets. The total Norwegian quota for red king crab increased from 220 metric tons in 2002 to 2350 metric tons in 2017, with a free-red king crab harvesting zone to the west of the quota-regulated area to prevent further expansion of the crab. At present, there is no established quota for snow crab. In 2016, a volume of about 5300 metric tons of snow crab was landed in Norway. In 2016, the export of red king crab and snow crab in Norway amounted to 529 million and 338 million Norwegian Kroner, respectively. Based on regular surveys of crab populations in the Barents Sea, it is assumed that the volumes red king crab and snow crab will remain steady and increase, respectively. Thus, these industries will continue to be important to the Norwegian seafood industry.

Allergies are the most common disorders of the immune system, estimated to affect about 20% of the general population. In the local setting, there is a dearth of information on the sensitization profiles of allergic individuals from Pampanga, Philippines to different allergen sources, thus, evaluation of the total and allergen-specific IgE levels of 100 sera samples from allergic asthma, rhinitis and dermatitis" individuals and 100 sera from non-allergic subjects to fifteen aqueous protein extracts were performed. The aqueous protein extracts prepared from three house dust mite species, three species of cockroaches, two species of fungi, pollens from two species of plants, peanut and four seafoods were quantitated using the BioRad Protein Assay. Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE) showed multiple bands ranging from 10-250 kDa. Enzyme-linked immunosorbent assay (ELISA) revealed significantly higher mean total serum IgE levels among the allergic groups than non-allergic subjects (p<0.0001). Unpaired t-test results indicated that except for the fungal, tree pollen and crab allergens, there is an extremely significant difference between the mean allergen-specific IgE of allergic subjects compared to the non-allergic subjects for each of the other eleven aqueous allergen extracts, taken separately. Of the allergic subjects, 72.00% exhibited multiple sensitizations to the fifteen aqueous allergen extracts. This study provides the allergenicity profile of "Kapampangan" allergic individuals which could pave the way for the design of highly specific and accurate diagnostic protocols for allergies among the local patients and may serve as an important basis for immunotherapy.
