A model for implementation of HACCP system for prevention and control of mycotoxins during the production of red dried chili pepper Ciênc. Tecnol. Aliment.
OZTURKOGLU-BUDAK,Sebnem.
Abstract Hazard analysis and critical control points (HACCP) is a process control system describes the potential hazards during food production flow chart. In contrast to the conventional way of ensuring product safety by end-product testing, HACCP establishes control systems, focuses mainly on preventive measures. Quality of red dried chili pepper (RDCP) should be assured by taking special care from harvesting of the peppers to retailing of the packaged product. RDCP is susceptible to fungi growth and mycotoxin contamination depending on the atmospheric and processing conditions such as humidity, temperature, storage and drying. Mycotoxins, are toxic metabolites to human health and strict control measures are required for preventing their occurrence in...

Aflatoxin removal of peanut meals with aqueous ethanol Scientia Agricola
Fonseca,H.; Regitano-d'Arce,M.A.B..
A preliminary approach to achieve compatible simultaneous extraction of aflatoxin and residual oil from pressed oil meals was conducted to determine the minimum amount of water to be added to ethanol versus necessary time to achieve complete removal of aflatoxin. Commercial anhydrous, 96, 93 and 90°GL ethanol were utilized in trials with Soxhlet extractors. Commercial anhydrous ethanol did not remove aflatoxin completely and the extraction efficiency in minutes was directly proportional to the amount of water present in the ethanol, as expected. Although 96°GL ethanol was efficient, alcoholic strengths between 96 and 99°GL need be evaluated to improve oil extraction, provided they do not decrease aflatoxin removal efficiency.

Association of the severity of tongue lesions in broiler chickens with the quality of corn in feed PAB
Vaccari,Isabel Cristina Mores; Duarte,Vinicius; Rodrigues,Denise Russi; Santos,Fabiana Ramos dos; Minafra,Cibele Silva.
Abstract: The objective of this work was to determine the correlation of the physical attributes of corn and the mycotoxins present in its grains with the severity of tongue lesions in broiler breeder roosters. The occurrence of the aflatoxin, vomitoxin, zearalenone, T-2 toxin, and fumonisin mycotoxins was detected in the corn grains used in the feed formulation for breeder chickens. The percentages of moisture and broken grains were positively correlated (Pearson’s correlation) with the presence of aflatoxin. Milder lesions (grade 1) are positively correlated with aflatoxin and negatively correlated with fumonisin, and the most severe lesions (grade 3) are positively correlated with vomitoxin, fumonisin, and T-2 toxin.

Comparison of methods by TLC and HPTLC for determination of aflatoxin M1 in milk and B1 in eggs Ciênc. Tecnol. Aliment.
Scussel,V. M..
Milk and egg matrixes were assayed for aflatoxin M1 (AFM1) and B1 (AFB1) respectively, by AOAC official and modified methods with detection and quantification by thin layer chromatography (TLC) and high performance thin layer chromatography (HPTLC). The modified methods: Blanc followed by Romer, showed to be most appropriate for AFM1 analysis in milk. Both methods reduced emulsion formation, produced cleaner extracts, no streaking spots, precision and accuracy improved, especially when quantification was performed by HPTLC. The use of ternary mixture in the Blanc Method was advantageous as the solvent could extract AFM1 directly from the first stage (extraction), leaving other compounds in the binary mixture layer, avoiding emulsion formation, thus...

Distribution of aflatoxin contamination in maize samples Ciênc. Tecnol. Aliment.
Gloria,Eduardo Micotti da; Ciacco,César Francisco; Lopes Filho,José Francisco; Ericsson,Cynthia; Zocchi,Silvio Sandoval.
The distribution of the aflatoxin contamination was studied among four maize fractions, separated according to Brazilian grading rules for maize. The fraction that contained fermented, moldy, heated and sprouted grains normally had the highest levels of aflatoxin. However, the fraction contribution to the whole sample contamination level took into account the contamination fraction level and its weight to the whole sample. Considering this, the fraction that contained insect damaged, hollow, up to ¼ fermented and grains damaged by other causes was normally the fraction responsible for the total contamination level in the samples. Nevertheless, the fraction contributions were variable from sample to sample. Therefore, in conclusion, it was not possible to...

Distribution of aflatoxins in contaminated corn fractions segregated by size BJM
Piedade,Fabiana S.; Fonseca,Homero; Glória,Eduardo M.; Calori-Domingues,Antonia; Piedade,Sônia M.S.; Barbin,Décio.
The efficiency of segregation, by particle size, in reducing the aflatoxin content of corn lots under the Brazilian conditions was studied. The aflatoxin content, in the corn fractions obtained after sieving thirty contaminated samples, with approximately 3.0 kg each, was determined. The samples were passed through 4.5 mm round-hole sieves and the fractions with particles ³4.5 mm (fraction A) and <4.5 mm (fraction B) and then analyzed for aflatoxins by TLC. The results showed that the distribution of the aflatoxins among the fractions A and B varied from sample to sample. However, the fraction B presented higher content (6 to 1,422 µg/kg) of aflatoxins (P<5%), than samples of fraction A (4 to 389 µg/kg). In spite of that the segregation of this...

Effects of Yeast Glucomannan and Sodium Bentonite on the Toxicity of Aflatoxin in Broilers Rev. Bras. Ciênc. Avic.
Azizpour,A; Moghadam,N.
ABSTRACT The aim of this study was to evaluate the efficacy of a yeast glucomannan (YG) and sodium bentonite (SB) in reducing the toxicity of aflatoxin for broilers fed a diet naturally contaminated with aflatoxin. In total, 300 7-day-old Ross 308 broilers were randomly assigned to 10 dietary treatments, consisting of a diet with no aflatoxin (positive control), a diet naturally contaminated with 250 ppb aflatoxin (negative control), and eight aflatoxin-contaminated diets supplemented with different SB and YG and their combinations. Serum biochemical parameters and liver pathological changes were investigated when broilers were 42 days old. The birds fed the negative control diet presented lower uric acid, cholesterol, and triglyceride levels and higher in...

Evaluation of yeast cell wall on the performance of broiles fed diets with or without mycotoxins Rev. Bras. Ciênc. Avic.
Santin,E; Paulillo,AC; Nakagui,LSO; Alessi,AC; Maiorka,A.
This experiment aimed at evaluating the effects of the interactions between aflatoxin (500 or 250 ppb) and ochratoxin (500 or 250 ppb), and the possible benefits of adding yeast cell wall to prevent the effects of these mycotoxins in broiler chickens. Relative organ weight gain and live performance were evaluated at 21 and 42 days of age. Results indicated that at the levels of mycotoxins included in the experimental diets, ochratoxin reduced feed intake and body weight gain, and aflatoxin only affect feed intake of 21-day-old birds. No interaction was observed between aflatoxin and ochratoxin at the levels used in experimental study. Yeast cell wall did not significantly reduced the deleterious effects of ochratoxins. No significant differences were...

Immobilized Saccharomyces cerevisiae as a potential aflatoxin decontaminating agent in pistachio nuts BJM
Rahaie,S.; Emam-Djomeh,Z.; Razavi,S. H.; Mazaheri,M..
In this study, we investigated the binding ability of Saccharomayces cerevisiae to aflatoxin in pistachio nuts. The obtained results indicate that S. cerevisiae has an aflatoxin surface binding ability of 40% and 70% (with initial aflatoxin concentrations of 10 and 20 ppb) in the exponential phase. Acid treatments increase this ability to approximately 60% and 73% for the two concentrations of aflatoxin, respectively. Heat treatments also enhance surface binding to 55% and 75%, respectively. Binding appears to be a physical phenomenon that saturates within the first 2-3 hours of the process. The obtained results indicate that yeast immobilization for toxin reduction on aflatoxin-contaminated pistachios had no effect on qualitative characteristics, such as...

Molecular characterisation of Aspergillus flavus isolates from peanut fields in India using AFLP BJM
Singh,Diwakar; Radhakrishnan,T.; Kumar,Vinod; Bagwan,N.B.; Basu,M.S.; Dobaria,J.R.; Mishra,Gyan P.; Chanda,S.V..
Aflatoxin contamination of peanut, due to infection by Aspergillus flavus, is a major problem of rain-fed agriculture in India. In the present study, molecular characterisation of 187 Aspergillus flavus isolates, which were sampled from the peanut fields of Gujarat state in India, was performed using AFLP markers. On a pooled cluster analysis, the markers could successfully discriminate among the ‘A’, ‘B’ and ‘G’ group A. flavus isolates. PCoA analysis also showed equivalent results to the cluster analysis. Most of the isolates from one district could be clustered together, which indicated genetic similarity among the isolates. Further, a lot of genetic variability was observed within a district and within a group. The results of AMOVA test revealed that...

Custódio,Letícia; Prados,Laura Franco; Yiannikouris,Alexandros; Holder,Vaughn; Pettigrew,James; Kuritza,Leandro; Resende,Flávio Dutra de; Siqueira,Gustavo Rezende.
ABSTRACT The objective of this survey was to identify what mycotoxins were present in ingredients used in diets offered to beef cattle in feedlots and their concentrations. The survey covered 30 Brazilian feedlots located in the five major beef-producing states. Samples of total mixed ration (TMR) and ingredients were collected and analyzed for mycotoxin using ultra-performance liquid chromatography coupled to tandem mass spectrometry. Mycotoxin concentrations were further interpreted according to known species-specific sensitivities and normalized according to the principles of toxic equivalent factors (risk equivalent quantities - REQ) expressed in µg kg−1 of aflatoxin B1-equivalent. Forty percent of the visited feedlots had apparent fungi in TMR....
