“…Spectroscopic methods such as near‐infrared (NIR), Raman, fluorescence, and hyperspectral imaging (HSI) techniques have been used for the nondestructive evaluation of quality and safety attributes of food and agricultural products for a while now (Boyaci et al., 2015). Some of these techniques are being applied to detect mycotoxins in foods (Wu et al., 2018). Spectroscopic detection methods represent the most widely nondestructive aflatoxin determination methods.…”

Aflatoxins represent a global public health and economic concern as they are responsible for significant adverse health and economic issues affecting consumers and farmers worldwide. Produced by fungal species from the Aspergillus genus, aflatoxins are a toxic, mutagenic, and carcinogenic group of fungal metabolites that routinely contaminate food and agricultural products. Climate and diet are essential factors in the aflatoxin contamination of food and subsequent human exposure process. Countries with warmer climates and staple foods that are aflatoxin‐susceptible shoulder a substantial portion of the global aflatoxins burden. Enactment of regulations, prevention of pre‐ and postharvest contamination, decontamination, and detoxification have been used to prevent human dietary exposure to aflatoxin. Exploiting their chemical and structural properties, means are devised to detect and quantify aflatoxin presence in foods. Herein, recent developments in several important aspects impacting aflatoxin contamination of the food supply, including: fungal producers of the toxin, occurrence in food, worldwide regulations, detection methods, preventive strategies, and removal and degradation methods were reviewed and presented. In conclusion, aflatoxin continues to be a major food safety problem, especially in developing countries where regulatory limits do not exist or are not adequately enforced. Finally, knowledge gaps and current challenges in each discussed aspect were identified, and new solutions were proposed.

“…Bu salgınlara mikrobiyal etkenin kendisi (Campylobacter, Salmonella gibi) ya da salgıladığı toksinler (Staphilococcus enterotoksinleri gibi) neden olabilir (5,6). Ayrıca, Aspergillus fumigatus kontaminasyonunun olduğu durumlarda (özelikle tahıl, fındık, kurulmuş meyve gibi ürünler), aflatoksin gibi mikotoksinler, uzun vadede karaciğer kanserine neden olabilir (7). Ek olarak, vakada tartışıldığı gibi süt ürünlerinin uygunsuz üretimi ve saklanması Brusellozis vakalarına neden olabilir.…”

Yalım ve Koşan'ın "Bugün günlerden Şeyhmus" başlıklı vaka analizi, bir gıda denetçisinin perspektifinden, gıda üretimi yapan bir işyerinin kapatılmasına dair karar sürecini ve bu sürecin işyeri sahibi ve ailesinin hayatları üzerindeki etkilerini etik perspektifiyle değerlendirmektedir. Bu süreç; toplum beslenmesi, iş sağlığı ve güvenliği, çocuk sağlığı gibi birçok halk sağlığı disiplini yönünden de analiz edilebilir. Toplum beslenmesi ve gıda güvenliği bağlamında, denetçinin sorumluluğu işletmeci ailenin ötesinde tüm toplumu ilgilendirmektedir. İşletmede çalışan işçilerin sağlığı ve işletmenin işyeri güvenliği yönünden değerlendirilmesi, gıda denetçisinin direkt olarak sorumluluğunda olmasa da ilgili kurumlarla işbirliği içinde olması şarttır. Ek olarak işletmede çalışacak çocukların sosyal güven içinde eğitimlerine devamında kamu ve sivil toplum kuruluşları da olası paydaşlar arasında yer almaktadır. Vakanın odaklandığı gıda güvenliği ve denetimi konusunda birden çok disiplinin tartışmada yer alması ve etik çatışmaların oluşması kaçınılmazdır. Ancak tüm bu tartışmalar, gıda güvenliği, iş sağlığı ve çocuk hakları konularında normların belirlenmesi ya da geliştirilmesinde fayda sağlayacaktır.

“…In‐line sorting and discrimination can be conducted based on quantifiable attributes, such as fungi and AFs, after setting sorting thresholds according to quality grade. At present, several developments in high‐speed sorting of nuts and dried fruits using spectroscopic techniques have been reported in many papers and patents (Wu, Xie, & Xu, ). Color imaging system for automated detection of contaminated pistachios was developed with a speed of 163 kg per hour (Pearson & Schatzki, ).…”

Aflatoxin (AF) contamination of peanuts represents a significant food safety risk. Developing a rapid and non‐destructive method for in‐line AF detection has received significant attentions. This study confirmed the effectiveness of a laser based in‐line AF sorting technology in a peanut processing factory, with 99% specificity and 75% sensitivity for aflatoxin B1 (AFB1). In total, 80 in‐line sorting trials were undertaken. The accepted samples from 99% trials had AFB1 below 10 μg/kg. In 75% of the trials, the AFB1 content of the rejected material exceeded 10 μg/kg by up to a factor of ca. 20. At a throughput of 2.4–4.0 tons per hour, the rejection rate ranged from 0.7 to 4.7%. No significant differences in AFB1 level and rejection rate were observed among different suppliers nor were there differences among the different quality grades. Overall, the sorter effectively removed AF contaminated peanuts without comprising the line throughput. Practical applications The validated in‐line sorting technology can be used in food factories for the control of aflatoxins in food samples such as oilseeds and grains. Furthermore, the technology can be developed for the control of other kinds of mycotoxins.
