Special Issue Information

Dear Colleagues,

Billions of people in the world are at risk of unsafe food. Many millions become sick while hundreds of thousands die annually due to the consumption of contaminated food. Seafood provides more than 4.5 billion people with at least 15% of their average per capita intake of animal protein. Nevertheless, along with the fast growth of human fisheries and aquaculture, intensive coastal aquaculture and excessive use of additives and antibiotics have become new challenges to food safety, particularly in developing nations. The resulting substantial changes in coastal ecosystems consequently increase the risk of seafood-borne infectious diseases. On the other hand, rapid global urbanization and industrialization may lead to the increasing pollution of the oceans, into which substantial amounts of waste are discharged, including hazardous heavy metals, organic pollutants, plastics, and radioactive compounds. Due to their long-term persistence and non-degradable nature, their accumulation in humans through the seafood chain continues to pose substantial threats to marine ecosystems and human health. Therefore, confronting these challenges requires rigorous scientific research. Advances in this field are expected to impact the food production/testing industry, governments, and food consumers.

Original and review papers dealing with all aspects of “Contaminants in Seafood: Prevention, Control, and Detection” are welcome for inclusion in this Special Issue of Foods. Research reports will focus on the following areas: development and/or improvement of rapid methods for the detection and/or identification of seafood-borne pathogenic and spoilage microorganisms and chemical contaminants; new approaches and/or strategies for controlling seafood-borne pathogens and spoilages; and non-biological contaminants; and recent discoveries in resurgence, pathogenesis, determining, and/or characterizing seafood-borne pathogens.

Kelp is a traditional healthy food due to its high nutritional content; however, its relatively high contents of iodine and arsenic have raised concerns about its edible safety. This study explored the effects of different cooking treatments on the contents of iodine and arsenic in kelp, evaluated the bioaccessibility and bioavailability of iodine and arsenic in kelp using in vitro digestion, and compared the differences in the transport characteristics of iodine in kelp and KIO3 using a Caco-2 monolayer cell transport model. The results show that the content of target elements that reached systemic circulation could be reduced by cooking and gastrointestinal digestion. The highest reductions in iodine and arsenic were 94.4% and 74.7%, respectively, which were achieved by boiling for 10 min. The bioaccessibility and bioavailability of iodine and arsenic were significantly improved by a cooking treatment. However, the contents of iodine and arsenic decreased significantly, with the bioaccessibility of iodine reducing from 3188.2 μg/L to 317.0 μg/L and that of arsenic reducing from 32.5 μg/L to 18.1 μg/L in the gastric phase after boiling. The findings also show that the efficiency of iodine transport in kelp and KIO3 was positively correlated with the transport time and negatively correlated with the concentration of iodine. With the increase in the iodine concentration, the rate of iodine transport in kelp decreased from 63.93% to 3.14%, but that of KIO3 was stable at around 35%, which indicates that the absorption efficiency of iodine from kelp was limited, even when too much kelp was ingested. In conclusion, the edible safety of kelp is significantly improved after cooking. The risk of excessive iodine and arsenic intake caused by consuming kelp is extremely low, and as an effective iodine supplement source, kelp has higher edible safety compared with KIO3. This study clarifies the safety of algae based on iodine and arsenic contents and also provides a basis for the formulation of food safety standards. Full article
