In global terms, a progressive loss of quality could be observed in fish muscle with increasing storage time. Comparisons between batches allowed us to conclude an inhibitory effe ...
... Antimicrobial photodynamic treatment (aPDT) is a light-based method developed for the inactivation of microorganisms. With the emergence of antifungal- and antibiotic-resistant microorganisms, aPDT has been suggested as a promising microbial control strategy. The treatment is based on a combination of visible light, a photosensitizer (PS), and molecular oxygen. Illuminating the PS with adequate li ...

... Although antimicrobials are valuable allies in animal production, their extended use has led to unexpected threats associated with the emergence and propagation of antimicrobial resistance. Moreover, when withdrawal periods in food-producing animals are not observed, antimicrobial residues can access the food chain, causing direct toxicity, allergies, and/or intestinal microbiota dysbiosis in cons ...

... Phenotypic antimicrobial resistance testing of 160 Campylobacter jejuni isolates from broiler caeca and neck skin samples collected at key stages during processing from 32 batches was conducted to: (i) determine the prevalence of antimicrobial resistance in C. jejuni isolates (ii) investigate if C. jejuni strains with particular resistance profiles were more frequently recovered at the end of proc ...

Abstract:
... Salmonella enterica serovar Indiana has become a widely prevalent non-typhoidal serovar in China in recent years. To improve the understanding of antimicrobial resistance and genetic bias in this emerging pathogen, a total of 214 S. Indiana isolates from foods, patients, and the environments in China from 2007 to 2016 were characterized for antimicrobial susceptibility, antimicrobial resistance-de ...
... Bacteria indicators have been widely developed but still need complicated techniques, instruments, or well-trained users. This is a proof-of-concept study to develop a straightforward and colorimetric bacterial indicator using bacteriophages (phages) as bio-receptors and simple biochemical reactions for high sensitivity. Among the various phages, phage T4 with a high specificity to Escherichia col ...
... The aim of this study was to investigate the antibacterial effect of blue light-emitting diode (blue-LED; 460–470 nm) combined with various chemicals at inactivating Escherichia coli O157:H7 on the surface of agar media and fresh produce. Fresh-cut apples and cherry tomatoes were immersed in antimicrobials (1 % ascorbic acid, 0.025 % carvacrol, and 0.125 % citric acid) or photosensitizers (0.0078 ...
... The gene encoding LysSTG2, a novel endolysin from Salmonella-lytic bacteriophage STG2, has been cloned, overexpressed, and characterized previously. In this study, LysSTG2 was used to control Pseudomonas aeruginosa and P. putida, which showed high sensitivity to LysSTG2, in bottled water, milk, chicken breast, salmon, and the biofilms formed on the surface of polystyrene resin and stainless steel. ...
... Energy dispersive X-ray fluorescence spectrometry (ED-XRF) and near-infrared reflectance spectroscopy (NIRS), two non-destructive and rapid techniques, were explored to classify the geographical origin of soybeans. Multivariate statistical methods, including principal component analysis (PCA), discriminant analysis (DA), and modified partial least squares (MPLS), were applied as a chemometric tool ...
... During preparation, processing, and distribution, the spoilage of meat products has been causing a negative economic impact in the meat industries. In addition, lipid/protein oxidation and deterioration resulting from microorganisms' development are other concerns verified during the storage of meat and meat derivatives. In this sense, the meat industry has designed biopolymers-based materials con ...
... Polydopamine/polystyrene fibers mat (PDA-PS FsM) was prepared as a novel solid phase extraction (SPE) adsorbent for the simultaneous extraction of multi-class veterinary drug residues in animal-original foods. On this basis, a screening method for the determination of 18 veterinary drug residues in 8 classes by UPLC-MS/MS was established. PDA-PS FsM was confirmed to have good adsorption-desorption ...

Abstract:
... Vegetables and fruits may contain pesticides, leading to several health complications after long-term exposure. The food byproducts of soybean and camellia seed cake contain abundant saponins but are poorly utilized. This study aimed to investigate the capacity of soybean byproduct-extracted saponins (SBE) and camellia seed cake-extracted saponins (CSE) to remove pesticide residues in fruits and v ...
food contamination; mycotoxins; oligonucleotides; public health; risk
Abstract:
... Mycotoxin prevalence in food is a global public health issue, that could impose severe economic burdens. To prevent risk of exposure to mycotoxins, it is of great importance to develop selective, sensitive, and reliable methods to monitor mycotoxin levels in food samples. Recent advances in nanotechnology have produced many nanomaterials with unique physical features and extensive effort has been ...

Abstract:
... Some bacteria decarboxylate amino acids as a means of resisting acid stress. It is a mechanism commonly used by bacteria in fermented dairy products. The decarboxylation of histidine to histamine occurs frequently in some types of cheese, but high concentrations of histamine can be harmful to consumers. Not all amino acid decarboxylation products are, however, undesirable. GABA, the decarboxylatio ...
... All junior high school (JHS) students are consumers of food, and as consumers, they have a role in preventing foodborne diseases (FBD) by properly preparing and handling of food. However, food safety is not integrated in the Philippine curriculum. Due to this gap, this study validated food safety lessons (FSLs) and determined if these educational materials enhanced retention of knowledge and skill ...
... Whole wheat breads are usually packed in low density polyethylene (LDPE) or polypropylene (PP) based packets, however, owing to a blanket ban on non-biodegradable plastics, packaging materials derived from renewable ligno-cellulosic fibers, are gaining prevalence. This study takes into account, the purchase intention, overall acceptance and storability of uncoated (U), functional chitosan coated ( ...
