“…To the best of our knowledge, this is the first study that evaluated the microbial contamination of both internal and external surfaces of coffee vending machines in Italy. Several studies around the world have been conducted on coffee contamination only, focusing on the search for chemical parameters [ 12 , 13 ].…”

The consumption of hot drinks dispensed from vending machines has become a common practice, both in workplaces and during free time. Every day, millions of bulk drinks are sold, but the quality of the products distributed may not always be guaranteed, as it is related to many factors such as the quality of the water, the raw materials used, and the effectiveness of the equipment’s cleaning system. The purpose of this study is to evaluate the hygienic-sanitary requirements of hot drinks and vending machine surfaces. The investigation highlighted the microbial contamination of both coffee and vending machine surfaces. Although the ”coffee break” is usually considered a moment of pleasure, apparently not subject to specific jurisdiction, the products dispensed can represent a health risk if the hygienic conditions are not fully respected. Therefore, official controls carried out by the Prevention Department represent a suitable way for evaluating and guaranteeing the hygienic-sanitary requirements, providing for corrective actions, when needed, to protect consumers.

“…Although it is an essential micronutrient for humans, high levels can be toxic and trigger redox Fenton-type reactions, which damage and ultimately destroy oxidative cells. Acute Cu poisoning in humans can cause gastrointestinal problems such as nausea or abdominal pain [9,17,18]. Cu can enter the food chain via tainted food, processed food, and soil that has been mineralized by agriculture.…”

“…Generally, atomic spectroscopic techniques such as atomic absorption spectrometry, in which flame (FAAS, flame atomic absorption spectroscopy) and graphite furnaces (ET-AAS, electrothermal atomic absorption spectroscopy) are used as ionization sources to determine the concentration of metals at ppm to ppb levels. By contrast, inductively coupled plasma spectroscopy with optical emission (ICP-OES) and with mass spectrometry (ICP-MS) are also used to estimate metal content at ultra-trace levels [7][8][9]. Given the widespread consumption of wheat-based sweets by a significant portion of the population over vast geographical areas, the current goal of this study is to look into the sweets' content of Mg, Ca, Mn, Fe, Co, Cu, Zn, Al, Cr, Ni, As, Cd, and Pb.…”

In recent years, there has been a growing concern about the negative impact of unforeseen contaminants such as metals in commonly consumed food items, which pose a threat to human well-being. Therefore, it is of utmost importance to evaluate the levels of these contaminants to guarantee the safe consumption of these food items. The goal of the current research is to determine the levels of essential (EMs: Mg, Ca, Mn, Fe, Co, Cu, and Zn) and potentially toxic metals (PTMs: Al, Cr, Ni, As, Cd, and Pb) in various brands of wheat-based sweets. One hundred samples were collected and analysed via flame atomic absorption spectrometry (FAAS) and inductively coupled plasma–optical emission spectrometry (ICP-OES). Also, the current study was to investigate the distribution, correlation, and multivariate analysis of 13 metals (Mg, Ca, Mn, Fe, Co, Cu, Zn, Al, Cr, Ni, As, Cd, and Pb). Hierarchical cluster analysis (HCA) and principal component analysis (PCA) were used to interpret the metals’ association. The concentration (mg/kg) ranges of EMs were, in order, Mg (12.70–65.67), Ca (24.02–209.12), Mn (1.32–9.61), Fe (4.55–111.23), Co (0.32–8.94), Cu (2.12–8.61), and Zn (2.60–19.36), while the concentration (mg/kg) ranges of PTMs were, in order, Al (0.32–0.87), Cr (0.17–5.74), Ni (0.36–1.54), Cd (0.16–0.56), and Pb (0.14–0.92), and As was not detected in any sample under investigation. The HCA data revealed that Co, Al, and Ni form clusters with other metals. Sweets are prepared at high temperatures, and the elevated temperatures can increase the likelihood of Ni and Al leaching from stainless steel. Tolerable dietary intake (TDI) values for Ni were higher than the values established by the European Food Safety Authority (EFSA). The CR value found for the Ni and Cr was at the threshold level of cancer risk, if an amount of 25 g were to be used over a lifetime. In a nutshell, this study highlights the monitoring of EM and PTM levels in wheat-based sweets, and from a food safety perspective, the study is important for consumers of wheat-based sweets.

“…These methods can also be applied to investigate potential coffee adulteration, ensure food safety and track the origin of the product. [12][13][14][15][16] The analytical techniques most oen used in these investigations are ame atomic absorption spectrometry, inductively coupled plasma optical emission spectrometry, and inductively coupled plasma mass spectrometry. Notwithstanding, these techniques require time-consuming and laborious analytical sequences that involve either sample digestion with concentrated inorganic acids under high temperatures, generating hazardous wastes, or the preparation of liquid suspensions aer a rigorous grinding step, which is prone to contamination.…”
