Climate change and seafood safety: human health implications

Worldwide, anthropogenic climate change
is now a reality and is already affecting the biology and ecology of
some organisms, as well as several chemical pathways. Little is known
about the consequences of climate change for the food system,
particularly seafood, comprising all stages from ‘‘farm to fork” (mainly
primary production, processing, transport and trading). In this
context, the current review aims to elucidate climate change impacts on
seafood safety and its human health implications. Both chemical and
biological risks are foreseen to impair seafood safety in the future as a
consequence of climate change; in particular, toxic metals, organic
chemicals residues, algal toxins and pathogens of both humans and marine
organisms. However, different species respond differently to such
stresses. Public health authorities will face new challenges to
guarantee seafood safety and to sustain consumers’ confidence in eating
seafood in a warmer world.
