Convenience foods are commonly packaged with plastic materials. Many of the phthalate plasticizers (PAEs) in the packages may migrate into the foods and cause health hazards. In the present study, the contents of some PAEs were analyzed in 283 convenience foods and the plastic packaging materials. Health hazards were assessed for infants, children and young people. The contents of diethylhexyl phthalate (DEHP), found in the samples rich in fat, ranged from below the limit of detection to 5.23 mg/kg. The content of dibutylphthalate (DBP) ranged from 0...

Maximum limits for PAHs content in honey and bee products are not set. The objective of this study was to conduct a market survey of honey for the presence of PAH16 with the aim of detecting potential contamination and health risks for consumers. A total number of 61 honey samples produced in the territory of Serbia were examined. The content of PAH16 was measured using a gas chromatography-mass spectrometric method. Large values were found in some samples: 140.6 µg/kg for chrysene, 136.3 µg/kg for benzo[ghi]perylene, 120...

Acrylamide, a colourless and odourless crystalline solid, formed via the Maillard reaction in food, has been reported with harmful properties for humans, such as toxicity and carcinogenicity. Three hundred and four processed food samples from 17 product types, collected in Hanoi, Vietnam, were analyzed by LC-MS/MS to measure the acrylamide concentration. The limit of detection (LOD) and the limit of quantification (LOQ) of acrylamide were 1 µg Kg-1 and 3 µg Kg-1 , respectively. Effectively, the highest acrylamide content is usually found in processed food, which is one of the primary reasons of increased acrylamide content in food...

Sixty-four table grape samples from different regions of Tunisia were collected during three consecutive years (2015-2017). The presence of 96 pesticides, including dithiocarbamates, was assessed. Pesticides identification and quantification were performed by liquid or gas chromatography, coupled to tandem mass spectrometry. All samples contained multiple residues (4 to 24 residues), with an average of 11.6 residues per sample. Individual concentrations of pesticides in grapes ranged from 0.01 to 5.86 mg kg-1 ...

Resorcylic Acid Lactones, including zeranol, anabolics listed in the group A4 of Directive 96/23/EC, are banned in Europe for use in animals since 1985. Zeranol, after administration to animals, is metabolized to taleranol and zearalanone. It can also naturally occur in the urine due to conversion of zearalenone that may be present in animal feed. In 2010-2017, in Poland, 7746 animal samples were tested for zeranol residues within the official monitoring program. In 13, zeranol was detected after screening...

A total of 576 samples marketed in China, including maize, maize flour, maize grits and maize meal, was determined for the simultaneous presence of 12 mycotoxins (FB1 , FB2 , FB3 , DON, 3-DON, 15-DON, ZEN, AFB1 , AFB2 , AFG1 , AFG2 and OTA) using a validated UPLC-MS/MS for multi-mycotoxin method. DON were the most widespread mycotoxins (63%), followed by FB1 (57%) and ZEN (46%). 78% of the samples was contaminated with at least one of these mycotoxins. Risk assessment indicated that maize and maize-derived food intake does not pose a potential risk for general adult population with respect to individual mycotoxin...

In Lebanon, apples are among the most consumed commodities; however, pesticide residues in apples have not been evaluated so far. Therefore, this study presents the occurrence of pesticide residues in apples produced in Lebanon during 2012-2016. A total of 212 samples were analysed for the presence of pesticides using the QuEChERS multi-residue extraction method, followed by GC-MS. Pesticide residues were not observed in 23% of the samples. Whereas pesticide residues were found in 77% of the samples, among them 61% exceeded the maximum residue limits (MRL) and 16% contained residues below the MRL...

The occurrence of free and hidden fumonisins in raw maize and maize-based products from China was investigated. A total of 58 samples were analyzed using high-performance liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Among all the samples, 66% were contaminated with free fumonisins above limits of quantitation, and a higher percentage of 86% was found for total fumonisins (free + hidden). The highest contamination levels were observed in dried maize kernels which appeared mouldy, with mean levels of 15,737 and 30,785 µg/kg for free and total fumonisins, respectively...

Commercially important marine fish, yellowfin tuna (YFT), and swordfish (SF), collected from the Indian Ocean around Sri Lanka were analysed for mercury (Hg) and cadmium (Cd) content. The ranges for Hg were < 0.07-1.60 and < 0.07-4.30 mg/kg, while for Cd < 0.006-0.134 and 0.006-0.180 mg/kg in YFT and SF, respectively. In SF 13.3% and in YFT 9.2% exceeded the 1 mg/kg limit for Hg, while 3.1% of YFT exceeded the 0.1 mg/kg limit for Cd. All other samples were well below the maximum limits. Human health risk assessment was investigated using Estimated Daily Intake, Total Hazard Quotient, Hazard Index, and Provisional Tolerable Weekly Intake values for Hg and Cd...

Rhodamine B (RhB) is a banned food additive and has been classified as illegal colourant. Therefore, the risk of RhB contamination should be strictly monitored. In this study, a sensitive UPLC-MS/MS method was applied to monitor RhB in 292 various spices such as chilli, pepper and tomato products. The results showed 22.7% of chilli powder samples, 18.5% of pepper powder samples, 11.1% of chilli oil samples and 9.1% of pepper oil samples were contaminated with RhB. Chilli powder contained RhB up to 44,935 μg/kg with an average of 743 μg/kg, pepper powder up to 65...

The aim of this study was to determine the heavy metals content of milk from cows fed with forage irrigated with waste water from industrial sources and the health risk to children. Milk samples were taken from milk collection tanks of eight localities in the state of Puebla. On average, the heavy metals in the milk had the following order Zn> As> Pb > Cr> Cu > Ni. Pb (0.03 mg kg-1 ) exceeded the Codex limits. For As the hazard index was 8.0 ± 0.4, which is far above 1. On the other hand, the individual risk of cancer showed a descending order Cr> As > Pb, while the risk of total cancer (0...

The purpose of this survey was to estimate the safety of ready-to-eat infant foods in terms of Pb and Cd content. The studied samples were ready-to-eat infant products: dinners (n = 74), soups (n = 27) and desserts (n = 82) containing components of animal origin: meat and/or milk. Cd and Pb content was determined using a GF-AAS method. The analysed products contained 1.82-3.54 µg Pb and 1.32-1.50 µg Cd per kg. The content of Pb per kg of the product can be represented as dinners > soups > desserts, whereas the content of Cd was dinners > desserts > soups...

Chinese tonic liquor is an important dietary supplement in daily use, but it often happens that illicitly adulterated drugs in Chinese tonic liquor could lead to food safety issues. In this survey, an analytical method consisting of a liquid chromatography-quadrupole-time of flight mass spectrometer (LC-Q-TOF-MS), coupled with quick easy cheap effective rugged safe (QuEChERS) pretreatment, was established for identification of phosphodiesterase type 5 enzyme (PDE-5) inhibitors in Chinese tonic liquors. 86 PDE-5 inhibitors were qualitatively analysed by employing information dependent acquisition mass spectrometry (IDA-MS) in comparison with the accurate mass of the protonated molecular ion, isotopic pattern, library and chemical formula...

Common carp meat was smoked in traditional conditions without filter and with zeolite, granular activated carbon, and gravel filters. The aim of this study was to determine the influence of using different filters in traditional smoking conditions on 16 polycyclic aromatic hydrocarbons from the Environmental Protection Agency list (16 US-EPA PAHs). Determination and quantification of PAHs were performed by gas chromatography-mass spectrometry (GC-MS). According to the obtained results, all examined samples of common carp meat smoked in traditional conditions were safe for consumers regarding to the European Commission Regulation on PAH content...
