“…Moreover, they stated that changes in CO 2 concentration, temperature, and water availability can have a positive, neutral, or negative impact on disease development. Similar conclusions were presented by Hernroth and Baden () regarding shellfish. They stated that a moderate increase in temperature may have a stimulating effect on antimicrobial activity and may counteract the negative effects of warming in the future.…”

The aim of the study was to examine similarities in notifications on main hazards within food reported in the Rapid Alert System for Food and Feed (RASFF) in 1979–2017. The main problems were mycotoxins in nuts, pathogenic microorganisms in poultry meat and fish, pesticide residues in fruits and vegetables, and heavy metals in fish. The increase in the number of notifications has been observed since 2002/2003. Products were notified mainly by Italy, Germany, and United Kingdom and originated from Asian and European Union countries. The notification basis was border control and official control, and the notification type was border rejections, information, and alerts. Notified products were not distributed and not placed on the market, distribution status could be also not specified, or distribution was possible, also to other countries. The risk decision on hazard was usually not made. Products were redispatched, withdrawn from the market, and destroyed, or import was not authorized. Remarks, which can be used to improve the RASFF database, were also presented. It was further pointed out that European law should significantly reduce the use of pesticides, drugs, and food additives, and European agriculture should be reoriented from an intensive farming to a more sustainable and ecological one.

“…Finally, an emerging summer pathogen of black rockfish caused skin ulcer disease (Zhang et al, 2019). Elevated temperatures may enhance the pathogenicity and adaptability of many marine microorganisms by increasing metabolism and decreasing generation time (Cohen et al, 2018;Hernroth & Baden, 2018). This may imply that, with continuing climate change, more emerging opportunistic pathogens will challenge the health of aquatic organisms (Larsen et al, 2018).…”

A serious disease was recorded in juvenile Pacific abalone in Fujian Province, China in 2018. Although this disease caused no obvious external lesions, affected abalone exhibited bleached pedal epithelial cells and a lack of attachment ability. Bacterial strains were collected and cultured from the mucus of moribund and healthy abalone. A novel method was developed for screening abalone pathogens, based on the important role of mucus in the innate immunity of marine organisms. Using bacterial isolation, sequence analysis, and experimental challenges in vitro and in vivo, we identified the bacterial strains pathogenic to abalone. We verified that abalone mortality rates were high when exposed to Pseudoalteromonas shioyasakiensis strain SDCH87 at high temperatures. This opportunistic pathogen had an outstanding growth ability in mucus, and disrupted first line mucosal immunity in the foot within three days. The unprecedented sea surface temperatures associated with the record-breaking 2018 heatwave in south China may have induced opportunistic pathogenic behavior in P. shioyasakiensis. To our knowledge, this is the first report to show that P. shioyasakiensis is a serious opportunistic pathogen of abalone, or possibly mollusks in general, in the context of a heatwave.

“…Further, heat stress in host organisms increases the amount of energy devoted to metabolic demands and respiration, leaving fewer resources for immunological function (Shields 2019). In the sea, ocean acidification and hypoxia further deplete host energy reserves and damage tissue, ultimately increasing susceptibility to infection (Hernroth and Baden 2018, Shields 2019, Schwaner et al 2020). These stressors often occur simultaneously, with consequences ultimately compounded (Burge et al 2014, Gobler andBaumann 2016).…”

The incidence of emerging infectious diseases (EIDs) has increased in wildlife populations in recent years and is expected to continue to increase with global change. Marine diseases in particular are relatively understudied compared to terrestrial disease, but they can disrupt ecosystem resilience, cause economic loss, or threaten human health. While there are many existing tools to combat the direct and indirect consequences of EIDs, these management strategies are often insufficient or ineffective in marine habitats compared to their terrestrial counterparts, often due to fundamental differences in marine and terrestrial systems. Here, we first illustrate how the marine environment and marine organism life history present challenges or opportunities for wildlife disease management. We then assess the application of common disease management strategies to marine versus terrestrial systems to identify those that may be most effective for marine disease outbreak prevention, response, and recovery. Finally, we recommend multiple actions that will enable more successful management of marine wildlife disease emergencies in the future. These include prioritizing marine disease research and understanding its links to climate change, preventatively increasing marine ecosystem health, forming better monitoring and response networks, developing marine veterinary medicine programs, and enacting policy that addresses marine and other wildlife disease. Overall, we encourage a more proactive rather than reactive approach to marine conservation in general and to marine wildlife disease in particular and emphasize that multi-disciplinary collaborations are key to managing marine wildlife health.
