in vitro detoxification of aflatoxin b1 deoxynivalenol fumonisins t 2 toxin and zearalenone by probiotic bacteria from genus lactobacillus and saccharomyces cerevisiae yeast
Probiotics and Antimicrobial Proteins, 2020Co-Authors: Agnieszka Chlebicz, Katarzyna ślizewskaAbstract:The aim of the following research was to determine the detoxification properties of probiotic Lactobacillus sp. bacteria (12 strains) and S. cerevisiae yeast (6 strains) towards mycotoxins, such as aflatoxin B1, deoxynivalenol, fumonisins, T-2 toxin and zearalenone, which pose as frequent Feed Contamination. The experiment involved analysing changes in concentration of mycotoxins in PBS solutions, after 6, 12 and 24 h of incubation with monocultures of tested microorganisms, measured by high-performance liquid chromatography (HPLC). We found that all strains detoxified the mycotoxins, with the highest reduction in concentration observed for the fumonisin B1 and B2 mixture, ranging between 62 and 77% for bacterial strains and 67–74% for yeast. By contrast, deoxynivalenol was the most resistant mycotoxin: its concentration was reduced by 19–39% by Lactobacillus sp. strains and 22–43% by yeast after 24 h of incubation. High detoxification rates for aflatoxin B1, T-2 toxin and zearalenone were also observed, with concentration reduced on average by 60%, 61% and 57% by Lactobacillus, respectively, and 65%, 69% and 52% by yeast, respectively. The greatest extent of reduction in the concentration for all mycotoxins was observed after 6 h of incubation; however, a decrease in concentration was noted even after 24 h of incubation. Thus, the tested microorganisms can potentially be used as additives to decrease the concentrations of toxins in animal Feed.

impact of mycotoxin Contamination in the animal Feed industry
Current opinion in food science, 2019Co-Authors: Alejandra Paola Magnoli, Valeria Lorena Poloni, Lilia Renee CavaglieriAbstract:Mycotoxin Contamination generally affects a large number of raw materials and finished Feed intended for animal production. The economic impact on livestock production encompasses both, the cost of eliminating contaminated Feed and the reduction in animal productivity. Therefore, the increase in veterinary care costs and technical efforts aimed at reducing mycotoxins negative effects. Cereals and by-products constitute the main ingredients of finished Feed in production animals. Food processing affects mycotoxin distribution and concentration. The mycotoxin distribution in cereal processing procedures is a worldwide problem due to the high economic and health impacts. The use of a safe diet in which the risk of mycotoxin Contamination can be minimized and the cost/benefit is accurately quantified should allow the maximization of herd productivity. The present review intends to address the problem of animal Feed Contamination describing the impact on animal health and productivity. Moreover, the economic impact generated by mycotoxins and their control in the animal Feed industry was considered.

The prevalence of Salmonella enterica in Spanish Feed mills and potential Feed-related risk factors for Contamination.
Preventive Veterinary Medicine, 2011Co-Authors: Gregorio J. Torres, F. Javier Piquer, Leonor Algarra, Cristina De Frutos, Odón J. SobrinoAbstract:Abstract A cross-sectional study was conducted in Spain to estimate the prevalence of Salmonella enterica in Feed mills and to identify and evaluate potential risk factors associated with Feed Contamination. A total of 3844 samples were collected from 523 different Feed mills using a stratified sampling method. Samples were tested for the presence of Salmonella using conventional culture methods. When the presence of Salmonella was detected, samples were further characterised using serotyping at the National Reference Laboratory (NRL) for animal Feed. Additional data about the biosecurity and hygiene measures, Feed material used and compound Feed produced, were collected by official veterinarians using a questionnaire in situ . In 144 of the Feed mills visited (28%), Salmonella were present. However, it was only isolated from 4.8% of samples taken from all of the Feed mills (3.5% from Feed materials, 3.2% from compound Feed and 12.5% from dust of the Feed mill facilities). Salmonella serovars of public health importance ( Enteritidis , Typhimurium , Infantis , Virchow and Hadar ), were detected in only 2.7% of Feed mills and in 0.3% of the samples studied. Logistic regression was used to investigate potential Feed-mill risk factors for the isolation of Salmonella . Feed mill intake pits were demonstrated to have an increased risk of culture-positive dust samples (OR = 6.4; 95% CI: 2.7–15.1). The Feed material used in the production of compound Feed was associated with recovery of Salmonella. Of the Feed material used, cotton seeds were identified as having the highest odds of Contamination (OR = 3.8; 95% CI: 1.7–8.3). Pelleting appears to reduce the chance of Contamination because non-pelleted compound Feed is 8 times more likely to be contaminated than pelleted compound Feed (OR = 8.2; 95% CI: 2.5–26.6). The role of the Feed itself in the epidemiology of Salmonella seems to be of limited importance as compound Feed is not frequently contaminated at the Feed mill level. This should not preclude Salmonella control measures from including all stages of Feed production and they should have a risk-based approach according to the findings of this study.
