Background: Use of snus and snus-like nicotine products is increasing, in particular among young people, in several Nordic countries and Estonia, while snus is legally on the market only in Sweden and Norway. Snus is available in a great variety of tastes and packaging particularly catering for young users. Recently, strong snus-resembling nicotine pouches have emerged on the market. This research investigates the regulatory means to counteract this development. Methods: European Union (EU) and national tobacco control legislation, case law of the European Court of Justice (CJEU) and relevant public health studies are analysed. Results: The research finds that the judgement of the CJEU relating to the sale of snus on Finnish ferries has not been enforced. Permitted large traveller imports for personal use have contributed to wide availability of snus in Finland. Even if the legislation in Sweden is in conformity with the exemption it obtained in the Accession Treaty, the public health impact of snus use for young people in its neighbouring countries has become considerable. Nicotine pouches, -which are not regarded as medical products in terms of medicine legislation, lack harmonised EU-wide regulation. Controlling smuggling across open borders is challenging. Conclusions: The legislation at the EU and national levels should be able to protect young people from new tobacco and nicotine products. It is urgent to harmonise regulation relating to new tobacco and nicotine products taking as a base a high level of protection of health as required in the Treaty on the Functioning of the EU.

The Relationship

Biogenic amines (BAs) and nitrites are both considered harmful compounds for customer health, and are closely correlated with the microorganisms in fermented mustard (FM). In this study, BAs and nitrite contents in fifteen FM samples from different brands were analyzed. The concentrations of cadaverine in one sample and of histamine in one sample were above the toxic level. Moreover, five FM samples contained a high level of nitrite, exceeding the maximum residue limit (20 mg/kg) suggested by the National Food Safety Standard. Then, this study investigated bacterial and fungal communities by high-throughput sequencing analysis. Firmicutes and Basidiomycota were identified as the major bacteria and fungi phylum, respectively. The correlations among microorganisms, BAs and nitrite were analyzed. Typtamine showed a positive correlation with Lactobacillus and Pseudomonas. Cadaverine and nitrite is positively correlated with Leuconostoc. Furthermore, thirteen strains were selected from the samples to evaluate the accumulation and degradation properties of their BAs and nitrite. The results indicated that the Lactobacillus isolates, including L. plantarum GZ-2 and L. brevis SC-2, can significantly reduce BAs and nitrite in FM model experiments. This study not only assessed the contents of BAs and nitrite in FM samples, but also provided potential starter cultures for BAs and nitrite control in the FM products industry.

Abstract Background: Since prescribed limits for histamine in fish have been set by various regulatory bodies around the world, the rapid, specific and easy determination of histamine is in high demand. Objective: The enzymatic histamine assay developed by Kikkoman Biochemifa Co. was validated. Methods: Fresh and frozen raw tuna, canned tuna in oil and water, and anchovy fish sauce were used for the validation study under the specific guidelines of the AOAC Research Institute Performance Tested MethodSM (PTM) program. Results: Good linearity (R2 > 0.9997) for histamine standard solutions, recovery rates (90.3–125.2%), and repeatability precisions (RSDr < 10%) were shown for all spiked tested matrixes. The claimed LOQ values, 20 and 10 mg/kg for solid fish and 160 and 80 mg/kg for fish sauce using a 1 and 2 cm optical path length spectrophotometer, respectively, were validated. The cross-reactivity test showed no positive interference of other biogenic amines, except for agmatine and putrescine. Moreover, no inhibition was confirmed among the 12 biogenic amines. Stability data supported the shelf life (42 months at 4°C), lot-to-lot consistency was demonstrated, and the method was shown to be robust. Independent laboratory testing using canned tuna in oil demonstrated that the recovery ranged from 93.5 to 124.7%, and the RSDr at all spike levels was <20%. Conclusions: The simple and rapid enzymatic histamine assay method has been successfully validated. Highlights: This histamine quantitative assay kit was qualified for PTM certification No. 041802.

The contents of biogenic amines histamine, putrescine, and cadaverine in fish sauce were determined and the bacteria isolated from the samples were evaluated for their amines degradation activity. Five fish sauce samples contained 62.5–393.3 ppm of histamine, 5.6–242.8 ppm of putrescine, and 187.1–704.7 ppm of cadaverine. Thirty three bacterial isolates produced all three amines, seven isolates produced one or two amines, and one isolate did not produce any amine in differential agar media. Since the strains that produced amines were not supposed to degrade them, only eight isolates were further identified and evaluated for their amines degrading capability. Bacillus amyloliquefaciens FS-05 and Staphylococcus carnosus FS-19 degraded histamine up to 59.9% and 29.1% from its initial concentration, respectively. Staphylococcus intermedius FS-20 and Bacillus subtilis FS-12 degraded putrescine and cadaverine up to 30.4% and 28.9%, respectively. Most isolates tolerated the salt concentration of up to 15% and temperature of up to 45°C. The current study provided new information on biogenic amines degrading bacteria, isolated from high-salt-content food products. The amines degradation activity of the bacteria is considered as strain rather than species specific.

Abstract Objectives The aim of the study was to determine differences between Locator and CM LOC attachment systems regarding patient satisfaction and wear of the abutments and their inserts. Plaque accumulation onto the polyetherketoneketone (PEKK) framework and polymethylmethacrylate (PMMA) was investigated for the implant-supported overdentures. Methods Seventeen edentulous patients were randomised to receive either Locator or CM LOC system for the first year. The total number of implants was 53. After the randomisation, 25 implants received Locator system, and 28 implants received CM LOC system in the first year. After a period of 12 months, the attachment system was exchanged from either Locator to CM LOC or vice versa. Oral Health Impact Profile (OHIP-14) questionnaires were used to evaluate patient satisfaction, chewing comfort, and pressure lesions. Prosthesis hygiene on the PMMA and PEKK surfaces was evaluated by using Stark plaque index. After the exchange of the abutments, they were stored until the end of the 24 months, and the surface wear of the abutments was analysed using a scanning electron microscope. Results Three patients (10 implants) died shortly before the end of the first year. Two patients (7 implants) received only Locator system since CM LOC was not indictable for their implant system. Patient’s satisfaction was increased when the attachment system was changed from Locator to CM LOC after 12 months of wearing time. Chewing ability and comfort were increased when the attachment system was changed from CM LOC to Locator after 12-month wearing time. There was no influence of the change of the attachment system on pressure lesions. The observed plaque accumulation was higher on the PMMA than on the PEKK surface. For the 8 investigated Locator abutments, the wear was within low and middle level. For the 28 investigated CM LOC abutments, the wear was within middle and high level for the terminal implants and between low and middle for the central implants (for patients who received 4 implants). Conclusions Patient’s satisfaction and wearing comfort can be improved with implant-supported overdentures with CM LOC abutments in comparison to Locator. There was no clear difference between both attachment systems concerning the chewing ability of the patients. Plaque accumulation was observed on both attachment systems in different areas. Plaque accumulation on PEKK surface was less than on PMMA surface. Clinical relevance The CM LOC attachment system offers stable and comfortable wearing conditions for implant-supported overdentures. The use of PEKK as a framework material could reduce the incidence of pressure lesions.

The objective of the study was to survey the common pesticides used in postharvest storage of agricultural produce within Makurdi, Nigeria and to test the knowledge of the farmers and marketers on the health effects of these chemicals. The study provides information on the type of pesticides used by farmers, marketers and consumers of stored agricultural food products such as cowpea, yam chips, cassava chips, sesame seeds, maize and soybeans being major farm produces found within Makurdi and Benue State in general. Selection of 100 respondents were done using simple random sampling techniques across five major markets (Modern, Wurukum, North bank, Wadata and High level markets) through structured interview schedule. Socio-economic characteristics of the respondents were analyzed using frequency and percentages. Percentages were used to determine the common storage pesticides used within Makurdi, storage time, the frequency of customer purchase and perceived health impact of the storage pesticides. Data obtained were analyzed using descriptive statistics. The results revealed that 51% of the respondents were males with 41% between the ages of 30-39. Married respondents accounted for 52% and 48% having household sizes of 1-5, only 20% had no form of formal education and 75% were marketers. In a multiple response schedule, aluminium phosphate tablets ranked 80% for storage pesticide while dichlovos was 60%, DDT 35%. Others such as endosulfan, gamalin, carbofuran, carbendazim and permethrin were between 5-15%. Furthermore the study revealed the use of many restricted and obsolete pesticides still in use within this state and in outrageous quantities which could pose health challenge to consumers of these food products.
