Highlights: [•] Eight biogenic amines were monitored in 112 samples of dairy products from the Czech Republic. [•] Cheeses were regional products obtained from farmer markets or directly from farms. [•] 10% of tested cheeses have dangerous amounts of biogenic amines (above 200mg/kg). [•] Levels of biogenic amines in fermented dairy products were regarded safe for consumers’ health.

Altogether 114 samples of alcoholic and non-alcoholic bottled beer produced in 28 breweries in the Czech Republic were monitored for levels of biogenic amines (BA) and polyamines (PA). The beers were analysed immediately after purchase and then at the end of the best-before period (storage temperature 8 ± 1 °C). The concentrations of histamine, phenylethylamine and tryptamine in the studied samples were very low (mostly under 30 mg L−1). The studied PA spermine and spermidine also occurred in small amounts. Nevertheless, the levels of tyramine, putrescine and cadaverine reached significant values, especially in alcoholic beers. In almost 25% of the tested samples of alcoholic beers (at the end of the best-before period), the total amount of all the monitored BA and PA exceeded the 'healthy' level of 100 mg L−1, which is considered toxicologically significant, especially in alcoholic beverages.

In the presented work, six Borrelia burgdorferi sensu lato isolates were recovered from Ixodes ricinus ticks and one strain of spirochete with uncertain taxonomic position isolated from Culexpipiens mosquito collected in the Valtice area (South Moravia, Czech Republic), as well as representative type strains, were further characterized by ribotyping and whole-cell protein fingerprinting. The ribotype patterns obtained with HindIII and EcoRV ribotype patterns showed good correlations with the recently proposed genotypes and grouped each genospecies in a well-separated cluster. The whole-cell protein profiles of genospecies were more heterogenous than the ribotype pattems. The non-identified spirochetal strain was clearly separated from the Borrelia isolates in both methods thus prooving their good capacity to characterize Borrelia burgdorferi sensu lato strains.

Abstract: The aim of the work was to monitor the content of 8 biogenic amines (histamine, tyramine, phenylethylamine, tryptamine, putrescine, cadaverine, spermidine and spermine) in 112 samples of raw freshwater and see fish, and other animals living in the water which are offered in restaurants in the Czech Republic. In approx. 15% of the sampled bodies, increased levels of biogenic amines (practically more than 100 mg/kg) have been observed. In 6 samples of fish, the concentration of histamine was higher than the limit specified in Commission Regulation (EC) No 2073/2005 (more than 200 mg/kg). The results pointed out the necessity of keeping the storage conditions (cooling and/or freezing chain) during the distribution of products to consumers. [Copyright &y& Elsevier]
