This work reports data on the occurrence of nine mycotoxins and two food processing contaminants - acrylamide and furan - in a total of 100 beers produced in Latvia. Mycotoxins were detected by high-performance liquid chromatography (HPLC) coupled with time-of-flight mass spectrometry, acrylamide by HPLC coupled with quadrupole-Orbitrap mass spectrometry, and furan by headspace gas chromatography-mass spectrometry. The most frequently occurring mycotoxins were HT-2 and deoxynivalenol (DON), which were detected in 52% and 51% of the analysed samples...

This study investigated mercury contamination levels in eight commercially valuable Crustacean species caught off the Central Adriatic and Tyrrhenian coasts of Italy. Total mercury levels were measured by Thermal Decomposition-Amalgamation-Atomic Absorption Spectrophotometry. Results showed a high variability among species with values ranging between 0.070 and 1.24 (mg kg-1 wet weight). The lowest mercury levels were detected in caramote prawn (Penaeus kerathurus), warty crab (Eriphia verrucosa) and European spider crab (Maja squinado), decapods living in shallow waters...

During 2016-2017, 156 samples of fresh milk samples were collected from local markets of Karachi-Pakistan and analyzed for aflatoxin M1 (AFM1 ) contamination using ELISA technique. AFM1 was detected in 143 (91.7%) samples, ranged from 20-3090 ng L-1 with a mean level of 346.2 ng L-1 . In 125 (80.1%) samples, the AFM1 contamination was greater than the maximum limit (ML = 50 ng L-1 ) set by EU. However, in 51 (32.7%) samples the AFM1 level was higher than the ML of 500 ng L-1 as assigned by the USA. Statistical analysis showed that the AFM1 level in milk samples from summer was significantly (P < 0...

Polycyclic aromatic hydrocarbons (PAHs) are food processing contaminants considered to be carcinogenic and genotoxic. Due to its drying process stage, teas may be contaminated with PAHs. The aim of the study was to validate an analytical method involving QuEChERS and HPLC-FLD for determination of PAH4 in teas and evaluate the contamination levels in 10 different types of teas from Brazil. Recoveries varied from 54-99% and RSDs from 1-21%. LODs and LOQs were from 0.03 to 0.3 µg/kg and 0.1 to 0.5 µg/kg, respectively...

A total of 77 traditionally smoked meat samples produced in Latvia, Lithuania, and Estonia were tested for the occurrence of four EU regulated polycyclic aromatic hydrocarbons (PAHs). Levels of PAHs exceeding the EU maximum levels for benzo[a]pyrene and for the sum of four PAHs (PAH4) were detected in 46% and 48% of the samples originating from Latvia. The detected BaP levels in smoked meats ranged from 0.05 μg kg-1 to 166 μg kg-1 , while the PAH4 content ranged from 0.42 μg kg-1 to 628 μg kg-1 . The mean dietary exposure to PAHs was estimated at the levels of 5...

Aluminium is an omnipresent part of everyday life. It is widely used in industry and furthermore in products like cosmetics, sun creams or it can be applied for instance as aluminium foil by consumers during food preparation in households. However, over the last decades the toxicity of aluminium for humans has been heavily discussed and is still not completely clarified. Therefore, food aluminium concentrations were investigated in different untreated foodstuff as well as a possible aluminium transfer from aluminium foil to food...

This study was conducted to determine the occurrence and levels of total aflatoxins in complementary foods (CFs) and their ingredients. A total of 126 samples collected from 20 Districts from Amhara, Tigray, Oromia and Southern Nations Nationalities and Peoples (SNNP) regions were analyzed for levels of total aflatoxins using enzyme linked immunosorbent assay (ELISA). Aflatoxins were detected in 62 out of 66 pre-milling samples with mean range of 0.3 - 9.9 µg/kg. Aflatoxins were also detected in 19 out of 20 post-production CFs and in all of the one-month stored CFs at households and grain banks, with a mean range of 0...

Cocoa powder and chocolate products are known to sometimes contain cadmium (Cd) and lead (Pb) from environmental origins. A convenience sample of cocoa powder, dark chocolate, milk chocolate, and cocoa nib products was purchased at retail in the U.S. and analyzed using Inductively Coupled Plasma Mass Spectrometry to assess Cd and Pb concentrations. Cd and Pb were evaluated in relation to the percent cocoa solids and to the reported origin of the cocoa powder and chocolate products. Cd ranged from 0.004-3.15 mg/kg and Pb ranged from <LOD-0...

A total of 243 samples of divers foodstuffs were analysed for glyphosate and AMPA using an LC/MS/MS method with a relatively low LOQ in the range of 0.0005 to 0.0025 mg kg-1. Main contributors for dietary glyphosate and AMPA intake were cereals and pulses. The results suggest that pasta is a very important foodstuff for dietary glyphosate residue intake in Switzerland. Interestingly all samples of wine, fruit juice and nearly all samples of honey tested positive for glyphosate although at very low levels. A dietary risk assessment was conducted...

This paper reports the occurrence of dehydroacetic acid in cheese and cheese coatings collected in Italy during Agricultural Ministry Official control. Dehydroacetic acid is an antimicrobial substance not allowed to be used in EU countries as a food additive, with unknown effects on human health. Dehydroacetic acid was measured by a validated HPLC method according to Commission Decision 2002/657/EC criteria in terms of specificity, linearity, precision and accuracy, limit of detection, and limit of quantification...

In total 7351 meat preparations and fresh processed meat products were analysed from 555 different Serbian meat producers over a 10-year period, 4.5 years before and 5.5 years after mandatory Hazard Analysis and Critical Control Points (HACCP) implementation. From the obtained results, it could be concluded that HACCP has contributed to a better alignment of practices with the legal provisions. The share of non-compliant samples dropped from 18.6% before HACCP to 8.3% after its mandatory implementation. Average sulphite concentrations for all categories of meat preparations and fresh processed meat products decreased by 43%, declining from 33...

The natural occurrence of fungi, mycotoxins and fungal metabolites was investigated in 100 samples of maize grains collected from south and southwestern Ethiopia in 2015. The maize samples were contaminated by Fusarium, Aspergillus and Penicillium species. Using liquid chromatography tandem mass spectrometry 127 secondary metabolites were analysed. Zearalenone was the most prevalent mycotoxin, occurring in about 96% of the samples. Zearalenone sulfate was the second most prevalent, present in 81% of the samples...

In the present study, 100 commercial breads and biscuits were investigated for the occurrence of deoxynivalenol (DON) and its acetylated derivatives 3-acetyldeoxynivalenol (3-Ac-DON) and 15-acetyldeoxynivalenol (15-Ac-DON). The target mycotoxins were determined by isotope dilution ultrahigh performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). DON was determined in 95% of the test samples with a mean value of 153.3 µg kg(-1). Compared with DON, 3-Ac-DON and 15-Ac-DON were far less frequently detected, with mean values of 1...

Forty samples of milk powder purchased in Uruguay were analysed to assess melamine levels. Trichloroacetic acid and acetonitrile were used to extract and precipitate milk proteins previously to clean up of the samples by solid-phase extraction and then were determined by liquid chromatography coupled to ultraviolet detection. The limits of detection and quantification of melamine were 0.006 mg kg(-1) and 0.019 mg kg(-1), respectively. Milk was fortified with melamine at three levels, producing average recoveries higher than 83...
