“…The most surprising result of the present work is that after 193 days from X‐ray treatment no significant differences in the acini diameters were recorded between irradiated and control crayfish, and the histology confirmed a recovered spermatogenesis and lack of signs of cellular degeneration. After 1 month from irradiation at the same dose extensive gonadal damage was described 15 and our results demonstrate that less than 193 days are sufficient to repair the irradiation damage or, at least, that the surviving staminal spermatogonia were able to restart a functional spermatogenesis. The possibility of compensating and recovering a few surviving cells has been demonstrated within the pancrustaceans on larvae of Drosophila melanogaster irradiated with 35 Gy.…”

BACKGROUND The sterile male release technique (SMRT) is a useful method applied for controlling invasive and pest species. However, the use of X‐rays can lead to negative effects on the survival and health conditions of sterilized males. RESULTS This study was set up to evaluate the functional integrity of physiological, morphological and behavioural responses in males of the red swamp crayfish, Procambarus clarkii (Girard, 1852), exposed to a dose of 40 Gy of ionizing radiation. Concerning physiological responses, the results showed that the irradiation dose, tested at 5, 12, 28, 35, 65, 99, 132 and 193 days after treatment, has no effects on glycaemic and plasmatic total protein levels measured as biomarkers for general stress indexes. Nevertheless, the significant reduction of circulating haemocytes and the basal levels of phenoloxidase (PO) activities recorded in 40‐Gy irradiated crayfishes indicate that the exposure shrinks their capability to mount a rapid nonspecific response, and higher levels of plasmatic total PO activity indicate the ability to compensate and maintain an inducible response. Histological analyses performed at the end of the experiment showed no morphological damage in the testicular acini of irradiated males. Moreover, behavioural responses to two different water stimuli (vaporization and jet), measured at 15 and 45 days after the irradiation, were not modified in exposed crayfishes compared to the control group. CONCLUSIONS These results confirm the validity of SMRT on young males when the breeding season is less than 4 months but exposure to X‐ray should be repeated at mid‐breeding season when temperatures allow a longer breeding season. © 2021 Society of Chemical Industry

“…The dose needed for sterilization in arthropods can reach 300 Gy in the case of Lepidoptera 11 . Sterilization by radiation is already used in some commercial crustaceans, such as Penaeus japonicus , 12 Palaemonetes pugio , 13 and Macrobrachium rosenbergii , 14 with X‐ray doses ranging from 10 12 to 640 Gy 15 …”

“…Figure 3d shows the conformational and line alterations of seafood antigenic epitopes caused by γ-irradiation. Recently, Muanghorn et al (2018) found that γ-irradiation caused the loss of protein band density in immunoblot analysis (with polyclonal anti-TM produced in rabbit) of TM in giant freshwater prawn (Macrobrachium rosenbergii) with doses of 10 and 15 kGy at a dose rate of 0.5 kGy/h. Specifically, γ-irradiation changed epitopes structure in allergens, causing the unrecognition by IgG.…”

Tropomyosin (TM) is a major allergen in crustaceans, which often causes allergy and is fatal to some consumers. Currently, the most effective treatment is to avoid ingesting TM, although most adverse events occur in accidental ingestion. In this review, the molecular characterization, epitopes, cross‐reactivity, and pathogenesis of TM are introduced and elucidated. Modification of TM by traditional processing methods such as heat treatment and enzymatic hydrolysis, and innovative processing technologies including high‐pressure treatment, cold plasma (CP), ultrasound, pulsed electric field (PEF), pulsed ultraviolet, microwave and irradiation are discussed in detail. Particularly, enzymolysis, PEF, and CP technologies show great potential for modifying TM and more studies are needed to verify their effectiveness for the seafood industry. Possible mechanisms and the advantages/disadvantages of these technologies for the mitigation of TM allergenicity are also highlighted. Further work should be conducted to investigate the allergenicity caused by protein segments such as epitopes, examine the interaction sites between the allergen and the processing techniques and reveal the reduction mechanism of allergenicity.

“…13 However, non-thermal processing could improve nutrition properties and reduce food immunoreactivity. 14,15 In particular, food irradiation, as a mature and effective food processing technology, treats foods that are safe for humans and do not cause nutritional problems below 10 kGy. 16,17 The FAO and WHO declared that the maximum absorbed dose provided to food should not exceed 10 kGy, unless it is for a legitimate technical purpose.…”
