“…The diversity and spatiotemporal distribution of HAB events have been recorded annually in the IOC-ICES-PICES Harmful Algal Event Database (HAEDAT) since 1987 [ 7 , 28 ]. The provided data confirm that the frequency of HABs is increasing globally, and the most common toxin groups in Europe are paralytic toxins (PSP—paralytic shellfish poisoning), lipophilic toxins (DSP—diarrhetic shellfish poisoning), and domoic acid (ASP—amnesic shellfish poisoning) [ 21 ]. Portugal and Spain are the European countries in which the most events are reported (669 and 649, respectively) [ 7 ].…”

“…Harmful algal blooms (HABs) are natural phenomena that occur along the coasts of all continents due to the massive proliferation of toxic phytoplankton (cyanobacteria, diatoms, dinoflagellates, and others) in waterbodies. Environmental disturbances, such as climate change, eutrophication, and the introduction of non-native species, are now recognized as factors that may have contributed to the increased frequency and geographic spread of these phytoplankton outbursts [ 21 , 22 , 23 ]. These events can occur in both large and small areas, depending on the ecology of the species and environmental conditions [ 24 , 25 ].…”

The agri-food industry has historically determined the socioeconomic characteristics of Galicia and Northern Portugal, and it was recently identified as an area for collaboration in the Euroregion. In particular, there is a need for action to help to ensure the provision of safe and healthy foods by taking advantage of key enabling technologies. The goals of the FOODSENS project are aligned with this major objective, specifically with the development of biosensors able to monitor hazards relevant to the safety of food produced in the Euroregion. The present review addresses the state of the art of analytical methodologies and techniques—whether commercially available or in various stages of development—for monitoring food hazards, such as harmful algal blooms, mycotoxins, Listeria monocytogenes, allergens, and polycyclic aromatic hydrocarbons. We discuss the pros and cons of these methodologies and techniques and address lines of research for point-of-care detection. Accordingly, the development of miniaturized automated monitoring strategies is considered a priority in terms of health and economic interest, with a significant impact in several areas, such as food safety, water quality, pollution control, and public health. Finally, we present potential market opportunities that could result from the availability of rapid and reliable commercial methodologies.

“…Data from the 2018 Rapid Alert System for Food and Feed report showed 22 notifications related to excessively high levels of natural toxins including marine biotoxins, whereas in 2019 there were 45 ( 26 , 27 ). However, the real number of cases may be higher, because the current epidemiological systems for biotoxin detection are ineffective ( 28 ).…”

Introduction Marine biotoxins are toxic substances that may cause illness and death in marine organisms and humans. This article disseminates the results of a 4-year study on the occurrence of marine biotoxins in raw bivalve molluscs purchased from Polish suppliers. Material and Methods A total of 256 samples of 8 different molluscs species were analysed for the presence of biotoxins using the ELISA method for paralytic shellfish poison, diarrhoetic shellfish poison, and amnaesic shellfish poison. Results The permitted limits of marine biotoxin content were not exceeded in any of the analysed samples and the majority of them were free from these compounds. Conclusion The results of the study indicate that the tested raw bivalve molluscs available in Poland were safe for consumers.

“…However, these methods still experience challenges while detecting low-abundance pathogens and microbial toxins. For example, they cannot discriminate live versus dead microbes or cultivate microorganisms to understand the diversity and complexity of microbial toxins (Consortium OPATHY & Gabaldón, 2019;Vale, 2020;Yang et al, 2019).…”

Phage‐based technologies for highly sensitive luminescent detection of foodborne pathogens and microbial toxins: A review

Foodborne pathogens and microbial toxins are the main causes of foodborne illness. However, trace pathogens and toxins in foods are difficult to detect. Thus, techniques for their rapid and sensitive identification and quantification are urgently needed. Phages can specifically recognize and adhere to certain species of microbes or toxins due to molecular complementation between capsid proteins of phages and receptors on the host cell wall or toxins, and thus they have been successfully developed into a detection platform for pathogens and toxins. This review presents an update on phage‐based luminescent detection technologies as well as their working principles and characteristics. Based on phage display techniques of temperate phages, reporter gene detection assays have been designed to sensitively detect trace pathogens by luminous intensity. By the host‐specific lytic effects of virulent phages, enzyme‐catalyzed chemiluminescent detection technologies for pathogens have been exploited. Notably, these phage‐based luminescent detection technologies can discriminate viable versus dead microbes. Further, highly selective and sensitive immune‐based assays have been developed to detect trace toxins qualitatively and quantitatively via antibody analogs displayed by phages, such as phage‐ELISA (enzyme‐linked immunosorbent assay) and phage‐IPCR (immuno‐polymerase chain reaction). This literature research may lead to novel and innocuous phage‐based rapid detection technologies to ensure food safety.
