“…Several studies demonstrated that warming might stimulate the production of microcystins, a group of cyclic heptapeptides causing acute and chronic effects derived from their endocellular activity and protein phosphatase inhibition. In a recent study, microcystin-RR and microcystin-LR were detected for the first time in mussel M. galloprovincialis, harvested from farms in the Thermaikos Gulf (Kalaitzidou et al, 2021).…”

Global warming affects the aquatic ecosystems, accelerating pathogenic microorganisms' and toxic microalgae's growth and spread in marine habitats, and in bivalve molluscs. New parasite invasions are directly linked to oceanic warming. Consumption of pathogen-infected molluscs impacts human health at different rates, depending, inter alia, on the bacteria taxa. It is therefore necessary to monitor microbiological and chemical contamination of food. Many global cases of poisoning from bivalve consumption can be traced back to Mediterranean regions. This article aims to examine the marine bivalve's infestation rate within the scope of climate change, as well as to evaluate the risk posed by climate change to bivalve welfare and public health. Biological and climatic data literature review was performed from international scientific sources, Greek authorities and State organizations. Focusing on Greek aquaculture and bivalve fisheries, high-risk index pathogenic parasites and microalgae were observed during summer months, particularly in Thermaikos Gulf. Considering the climate models that predict further temperature increases, it seems that marine organisms will be subjected in the long term to higher temperatures. Due to the positive linkage between temperature and microbial load, the marine areas most affected by this phenomenon are characterized as 'high risk' for consumer health.

“…The genera of Synechocystis sp. isolated from the Thermaikos gulf in the current study produced microcystins during the experimental exposure of Mediterranean mussels Mytilus galloprovincialis at levels up to 6.85 ± 0.220 µg/kg after 72 h of exposure at a density of 100,000 cells/mL [31]. More than 150 genera of cyanobacteria have been described so far.…”

“…Cyanobacteria classified morphologically as Synechocystis sp. were chosen for sequencing since they are prone to producing microcystins [31]. Alignment of the sequenced fragments resulted in the read of 976 base pairs, which were further phylogenetically analyzed in comparison with closely related species obtained from GenBank.…”

Taking into consideration the essential contribution of Mytilus galloprovincialis farming, it is of rising importance to add knowledge regarding bacterial species occurrence in water samples from aquaculture zones from the point of view of both the organism and public health. In the present study, we investigated the bacterial community existing in water samples from six Mytilus galloprovincialis aquaculture areas in the Thermaikos gulf, northern Greece, that may provoke toxicity in aquatic organisms and humans and may indicate environmental pollution in mussel production as well as algal blooms. Bacterial species were identified molecularly by sequencing of a partial 16s rRNA segment and were analyzed phylogenetically for the confirmation of the bacterial taxonomy. The results obtained revealed the presence of four bacterial genera (Halomonas sp., Planococcus sp., Sulfitobacter sp., and Synechocystis sp.). Members of the Halomonas and Sulfitobacter genera have been isolated from highly polluted sites, Planococcus bacteria have been identified in samples derived directly from plastic debris, and Synechocystis bacteria are in line with microcystin detection. In this context, the monitoring of the bacteria community in mussel aquaculture water samples from the Thermaikos gulf, the largest mussel cultivation area in Greece, represents an indicator of water pollution, microplastics presence, algal blooms, and toxin presence.
