Abstract Introduction Histamine is one of the most important and toxic biogenic amines which may be present in food and may cause food poisoning in humans when contained at a high level. It is produced during bacterial decarboxylation of histidine in fish muscles. The aim of the study was to investigate the presence of histamine in fish and fish products available in Poland during 2014–2018. Material and Methods A total of 421 samples of raw (248), smoked (107), canned (50), and marinated fish (16) were analysed by high-performance liquid chromatography with diode array detection. Results Histamine was detected in 14.1% samples of raw fish, 29% of smoked fish, 22% of canned fish and 93.8% of marinated fish in concentrations ranging from 3.4 to 156.4 mg/kg. Content of this amine above 100 mg/kg was found in four samples: raw Atlantic salmon, smoked European sprat and two samples of marinated Atlantic herring. Conclusion The study showed that fish and fish products on the Polish market generally meet the food safety criteria for histamine and are safe for consumers.

Wheat Kernels

The aim of this study was to investigate the distribution of zearalenone in wheat kernels contaminated with this mycotoxin. Kernels from a sample of a wheat harvest affected by Fusarium culmorum were sorted into six groups according to their visual attributes. Milled portions of these groups were analysed by high-performance liquid chromatography with fluorescence and diode array detection. The clean-up was performed with an immunoaffinity column after methanol/water (4:1, v/v) extraction. The zearalenone content of the unsorted kernel fraction was 74 µg/kg. The group of healthy-looking kernels was contaminated with only 6 µg/kg of zearalenone. The groups of kernels that appeared shrunken and chalky white, damage routinely caused by Fusarium, were contaminated with 170 and 117 µg/kg, respectively. A remarkably high level of zearalenone contamination, 2,184 µg/kg, was observed for the group of reddish kernels. An association between the presence of the red pigment aurofusarin and high levels of zearalenone was found. Therefore, this pigment may be used as a marker of high zearalenone content.

Abstract The high performance liquid chromatography with diode array detection was used for the study. The histamine was detected in 14.6% and 17.8% of the samples of fresh and smoked fish respectively. The highest concentrations of the compound were found in smoked herring and smoked sprat (17.7 mg/kg and 24.1 mg/kg respectively). Histamine concentration in fresh and smoked fish did not exceed the allowable limit, indicating that they are safe for consumers.

The aim of this study was to find sources of Listeria monocytogenes contamination in fish products from a fish farm. The occurrence of L. monocytogenes also was compared in two freshwater fish farms with different types of fishponds. Samples collected from chilled rainbow trout (Oncorhynchus mykiss) and the slaughterhouse environment did not contain L. monocytogenes, but Listeria innocua was found in two samples from the slaughterhouses. Ten isolates of L. monocytogenes were discovered in sediment and water samples from farming tanks and earth ponds. Further characterization by serovar revealed the same serovar (1/2a) for all the isolates. Pulsed-field gel electrophoresis was used to divide the isolates into five different pulsotypes, three of which have been identified previously in fish products on the retail market. This finding supports the assumption that the primary production, and probably the raw fish, is a source of Listeria contamination in fish products. Some of the isolates were associated with a certain type of fishpond, indicating the need for hygienic analysis of the suitability of different types of farming ponds.

Digitization offers significant opportunities for the formulated product industry to transform the way it works and develop new methods of business. R&D is one area of operation that is challenging to take advantage of these technologies due to its high level of domain specialisation and creativity but the benefits could be significant. Recent developments of base level technologies such as artificial intelligence (AI)/machine learning (ML), robotics and high performance computing (HPC), to name a few, present disruptive and transformative technologies which could offer new insights, discovery methods and enhanced chemical control when combined in a digital ecosystem of connectivity, distributive services and decentralisation. At the fundamental level, research in these technologies has shown that new physical and chemical insights can be gained, which in turn can augment experimental R&D approaches through physics-based chemical simulation, data driven models and hybrid approaches. In all of these cases, high quality data is required to build and validate models in addition to the skills and expertise to exploit such methods. In this article we give an overview of some of the digital technology demonstrators we have developed for formulated product R&D. We discuss the challenges in building and deploying these demonstrators.<br>

Anisakis simplex is a zoonotic nematode which can cause human anisakiasis. Furthermore, A. simplex allergens, even of dead larvae can cause allergic reactions, including anaphylaxis. Due to the frequent occurrence in fish muscles and pathogenicity, A. simplex is a serious danger for fish products consumers. Therefore, it is necessary to examine fish and fish products for the presence of these parasites before placing on the market. The purpose of this paper is review of methods for A. simplex detection in fish and fishery products. These methods differ according to the effectiveness and type of the target analyte. They also have different suitability for examination of matrices with different properties. Moreover this paper presents legislations associated with A. simplex detection. .
