1. The objective of this study was to investigate in vitro and in vivo (in broiler chickens) ochratoxin A (OTA) adsorption efficiency of three different adsorbents: inorganic (modified zeolite); organic (esterified glucomannans) and mixed (inorganic and organic components plus enzymes). 2. The aim of the study was to investigate which of these adsorbents provided the best protection against the presence of residues of OTA in the pectoral muscle and liver of broilers given an OTA-contaminated diet. In addition, it was important to test and compare the results of adsorbent efficiency using two different in vitro methods. 3. The results from classical in vitro investigations carried out in the artificial intestinal fluid, showed that the inorganic adsorbent (Mz), exhibited the highest adsorption, having adsorbed 80.86 ± 1.85% of OTA, whereas average in vitro adsorption abilities of organic (30.52 ± 3.50%) and mixed (32.00 ± 2.60%) adsorbents were significantly lower. 4. In the investigation of absorption in everted sacs of broiler duodenal segments (Everted Duodenal Sacs Procedure), higher OTA adsorption in gut was exhibited by organic adsorbent, 74.26 ± 4.48%. Furthermore, the mean adsorption efficiency of mixed and inorganic adsorbent was 65.26 ± 4.76% and 45.75 ± 7.14%, respectively. 5. In the in vivo investigation, broilers were fed for 21 d on diets containing 2 mg/kg of OTA and supplemented with inorganic (Mz), organic (Ms) or mixed adsorbent (Mf) at the recommended concentration of 2 g/kg of feed. All three adsorbents significantly decreased OTA residue concentrations in the pectoral muscle and livers, but the order of effectiveness was mixed > organic > inorganic. The most efficient was the mixed adsorbent which decreased residue concentration by 72.50% in pectoral muscle and 94.47% in livers. 6. The Everted Duodenal Sac in vitro method provided results similar to those obtained in the in vivo study. However, further studies are required to investigate the efficiencies of adsorbents against various mycotoxins using this method. © 2013 Copyright British Poultry Science Ltd.

A wide spectrum of filamentous fungi is often found in various food commodities, where they can cause extensive damage and lead to sizable economic losses. The occurrence of their toxic metabolites - mycotoxins - constitutes a high risk for human and animal health. Although prevention of fungal growth and mycotoxin production on plants and in feedstuffs is usually considered as the best approach to impede the harmful effects on animal and human health, decontamination/detoxification of contaminated products is also of prime importance. Since the general public requires high quality, preservative free, safe but mildly processed food with extended shelf life, biopreservation, the control of one organism by another, has received much attention lately. Among the different potential decontaminating microorganisms, the group of the lactic acid bacteria has been considered as the most promising natural biological antagonists. Data have shown that many lactic acid bacteria can inhibit mould growth and that some of them have the potential to interact with mycotoxins. This review summarizes recent data about potential control of mould growth and mycotoxin production by lactic acid bacteria and highlights that they are very promising biological agents for food safety. © 2012 University of Bucharest.

Fish meal and fish oil represent main protein and lipid sources in fish feed, but there is a growing need for sustainable alternatives to these ingredients. In this study, four isolipid extruded diets for carp (. Cyprinus carpio L.) were used: ROHP (rapeseed oil-high protein), FOHP (fish oil-high protein); ROLP (rapeseed oil-low protein) and FOLP (fish oil-low protein). The trial lasted 75 days. No statistically significant effect of oil source or protein level or interactions of these factors was observed in final body weight, growth parameters or in feed conversion ratio. Protein sparing effect and omega-3 sparing effect were observed in the present study. The results of this experiment showed no negative effects on growth parameters, or major detrimental effects on fatty acid composition of muscle tissue in common carp when fish fed with diets supplemented with rapeseed oil (RO). Furthermore, an enhanced protein sparing effect was observed, when fish fed with lower protein diets, but significant accumulation of crude lipid was observed as a result of lowering protein level. The results of this study showed that diets supplemented with rapeseed oil can be used successfully in common carp cage production. © 2014 Elsevier Inc.

Toxins | Year: 2010

Mycotoxins are toxic compounds, produced by the secondary metabolism of toxigenic moulds in the Aspergillus, Alternar ia, Claviceps, Fusarium, Penicilliu m and Stachybotrys genera occurring in food and feed commodities both pre- and post-harvest. Adverse human health effects from the consumption of mycotoxins have occurred for many centuries. When ingested, mycotoxins may cause a mycotoxicosis which can result in an acute or chronic disease episode. Chronic conditions have a much greater impact, numerically, on human health in general, and induce diverse and powerful toxic effects in test systems: some are carcinogenic, mutagenic, teratogenic, estrogenic, hemorrhagic, immunotoxic, nephrotoxic, hepatotoxic, dermotoxic and neurotoxic. Although mycotoxin contamination of agricultural products still occurs in the developed world, the application of modern agricultural practices and the presence of a legislatively regulated food processing and marketing system have greatly reduced mycotoxin exposure in these populations. However, in developing countries, where climatic and crop storage conditions are frequently conducive to fungal growth and mycotoxin production, much of the population relies on subsistence farming or on unregulated local markets. Therefore both producers and governmental control authorities are directing their efforts toward the implementation of a correct and reliable evaluation of the real status of contamination of a lot of food commodity and, consequently, of the impact of mycotoxins on human and animal health. © 2010 by the authors; licensee Molecular Diversity Preservation International, Basel, Switzerland.

In Serbia, infection with Trichinella spp. has been recognized as a human health and animal husbandry problem for almost a century. The rate of swine infection gradually decreased from 0.14% to 0.02% between 2001 and 2010. For the past 5 years, Trichinella infections among swine were detected at levels higher than 0.05% in 3 districts of Serbia while prevalence persisted at lower levels for the rest of the country. During this 10-year period, there were 2257 cases of human trichinellosis, including 3 deaths; however, a significant decrease in the number of cases was reported during the last 5 years (fewer than 200 cases per year). The fact that prevalence data presented here are similar to prevalence data from 1990 indicates that this period of 10 years was needed to overcome the re-emergence of Trichinella infection in swine and humans that occurred during the last decade of the previous century. © 2013 Elsevier B.V.
