“…The co-occurrence of CPA and AFs has been reported by several investigators [11,12,55,56]. In addition, Smith et al [57] demonstrated possible synergistic and cumulative efects of the two mycotoxins [17]. The levels of alatoxin in 27 of the 102 samples analyzed were found to be over 20 μg/kg [58], determined by the FDA.…”

“…The frequency of detection was 60% for the Caiapó, with mean levels ranging from 304.1 to 2583.7 μg/kg, and 74.3% for the 886, with levels ranging from 288.0 to 4918.1 μg/kg [17]. Other studies investigating the production of CPA in peanuts also reported high rates of 89 [52], 93 [53], and 97% [54].…”

“…According to Ding et al [41] low AFs contamination is found in peanuts after harvest, but AF levels might be higher during storage and processing. It is therefore, necessary to monitor the AFs contamination status of peanuts during growth, storage, and processing [17].…”

“…Another mycotoxin is cyclopiazonic acid (CPA), which causes necrotic foci in internal organs such as the liver and exerts neurotoxic efects [17]. Natural occurrence of CPA has been reported in peanuts, corn, cheese, tomato products, and also meat, eggs, and milk of animals that are fed by contaminated feeds [18].…”

Alatoxin (AF) and cyclopiazonic acid (CPA) contaminations are very important problems for peanuts and its products. The aim of the study was to detect alatoxin (types B and G) and cyclopiazonic acid (CPA) occurrence and critical periods of toxin production in peanuts collected from diferent research areas of Osmaniye and Adana, Turkey, in 2015. Peanut kernels toxin analysis was performed in four diferent periods during the harvest, drying, prestorage, and storage. Total alatoxin occurrence in peanut kernels was analyzed by immunoainity chromatography-reversed-phase high-performance liquid chromatography (IAC-HPLC) analysis and cyclopiazonic acid occurrence in peanut kernels was analyzed by thin layer chromatography (TLC). Alatoxin levels in 76 out of 102 contaminated samples were from 0.3 to 1333.42 μg/kg. Cyclopiazonic acid levels in 18 out of 102 peanut samples were from 16.6 to 44.44 μg/kg. An unusual patern of mycotoxin production (alatoxin types B and G simultaneously with CPA) was seen in 11 of 102 peanuts samples. Six of nine samples were from the storage period. Alatoxin contamination during harvesting (64%) and drying (75%) were higher than prestorage (53%). Alatoxin (93%) and cyclopiazonic acid (30%) were the most produced during storage. The results showed that storage period was signiicantly important for the presence of two mycotoxins according to the statistical analysis.

Aspergillus flavus é um fungo filamentoso que pode produzir aflatoxinas e ácido ciclopiazônico, sendo que a presença dessas micotoxinas em alimentos e rações pode levar a um efeito tóxico no homem e em animais. Cepas de A. flavus produtoras de aflatoxinas e ácido ciclopiazônico são frequentemente isoladas do amendoim, indicando a natural co-ocorrência dessas toxinas neste substrato. Neste estudo, foram isoladas 47 cepas de Aspergillus flavus em grãos e cascas de amendoim durante diferentes fases de maturação do fruto e também durante seu armazenamento. Das cepas isoladas, foram avaliados os potenciais para produção de aflatoxinas e ácido ciclopiazônico, em que 91,5% foram produtoras de aflatoxinas e 70% produziram ácido ciclopiazônico, sendo que 63,8% produziram ambas as toxinas e 2,1% não produziu nenhuma. A presença de cepas toxigênicas de A. flavus nas amostras de amendoim analisadas indica um risco potencial da contaminação deste produto, caso seja exposto a condições ambientais favoráveis ao crescimento do fungo e produção de micotoxinas.

This chapter deals with airborne particle contamination in food processing indoor environments and particularly within heating, ventilation, and air-conditioning (HVAC) systems in food factory buildings. The major types of bioaerosols encountered in the food manufacturing sector as well as the bioaerosol sampling methods are firstly introduced. Secondly, some features of air handling systems such as zoning, cleanrooms, localized air handling systems, and HVAC systems are presented. Besides, the study of particle deposition to duct surfaces from turbulent airflow is reviewed and discussed. Substantially, an original work combining industrial diagnosis and experiments at factory scale with experiments at laboratory scale is then proposed through the case study of the CleanAirNet project. The CleanAirNet project (Hygienic Design of Ventilation Duct Networks in Food Factories) aimed at producing new knowledge, models, and techniques to help control the safety of the food products through a better control of aerosol particle transport and deposition in the ventilation networks of the food industry. The different work packages of the project are presented relatively to the state-of-theart particle deposition on duct surfaces. The methodological findings and relevant applications (e.g., a newly patented particle trapping device for air handling systems) for food industries are exposed. The
