Wang, Sheng et al. The presence of fish bones is now regarded as an important hazard in fishery products, and there is increasing demand for new analytical techniques to control it more effectively.

Bolarinwa, Islamiyat Folashade et al. Consumption of cyanogenic plants can cause serious health problems for humans. The ability to detect and quantify cyanogenic glycosides, capable of generating cyanide, could contribute to prevention of cyanide poisoning from the consumption of improperly processed cyanogenic plants. Hapten-protein conjugates were synthesized with amygdalin and linamarin by using a novel approach.

Cao, Xu-Liang et al. A sensitive and selective gas chromatography–mass spectrometry method was developed and validated for simultaneous analysis of bisphenol A (BPA) and three other bisphenols, bisphenol B (BPB), bisphenol E (BPE), and bisphenol F (BPF).

Assunção, Ednei et al. The aim of this study was to evaluate the effects of gamma radiation (GR) and electron beam (EB) on Brazil nut samples contaminated with Aspergillus flavus. Fifty samples were spread with an A. flavus suspension and incubated at 30°C and a relative humidity of 93%. After 15 days of incubation, mycobiota and aflatoxin analysis were performed.

Nakano, Miyo et al. A quantitative real-time PCR assay was developed to specifically detect and quantify Moorella thermoacetica and/or Moorella thermoautotrophica from canned coffee beverages. Six different combinations of newly designed primers were examined, and primer pair v1-1F/v4R was found to specifically amplify M. thermoacetica and M. thermoautotrophica. The minimum detection sensitivity was 15 fg of pure culture DNA from M. thermoacetica.

Symes, Sally et al. Seed sprouts have been implicated as vehicles for numerous foodborne outbreaks worldwide. Seed sprouts pose a unique food safety concern because of the ease of microbiological seed contamination, the inherent ability of the sprouting process to support microbial growth, and their consumption either raw or lightly cooked.

Kim, Do-Kyun et al. This study was undertaken to compare the effect of the spindle and stomacher for detaching microorganisms from fresh vegetables. The spindle is an apparatus for detaching microorganisms from food surfaces, which was developed in our laboratory. When processed with the spindle, food samples were barely disrupted, the original shape was maintained, and the diluent was clear, facilitating further detection analysis more easily than with stomacher treatment.

Lydon, Keri Ann et al. Raw oyster consumption is the most common route of exposure for Vibrio spp. infections in humans. Vibriosis has been increasing steadily in the United States despite efforts to reduce the incidence of the disease. Research has demonstrated that ice is effective in reducing postharvest Vibrio spp.

Kiermeier, Andreas et al. Australia exports about 150,000 to 200,000 tons of manufacturing beef to the United States annually. Each lot is tested for Escherichia coli O157 using the N-60 sampling protocol, where 60 small pieces of surface meat from each lot of production are tested. A risk assessment of E.

Saiyudthong, S. et al. A multiplex PCR assay for simultaneous detection and differentiation of Campylobacter jejuni, Campylobacter coli, and Campylobacter lari was developed and validated to assess the occurrence of these bacteria in fresh chicken meat and by-products in Bangkok, Thailand, by using a new combination of four previously published PCR primers for C. jejuni, C. coli, C. lari, and a universal 16S rDNA gene as an internal control.

Sharma, C. S. et al. The efficacy of the recently approved Salmonella lytic bacteriophage preparation (SalmoFresh) in reducing Salmonella enterica serotype Heidelberg on turkey breast cutlets and ground turkey was evaluated. In a broth model assay, the phage preparation completely inhibited the growth of four S. enterica serotypes (Salmonella Enteritidis, Salmonella Heidelberg, Salmonella Kentucky, and Salmonella Typhimurium) at 37°C at a multiplicity of infection of 10,000 PFU/CFU.

Kuruc, Julie et al. Cereal grains are a significant source of ochratoxin A (OTA) in the human diet. Multiple ochratoxigenic Aspergillus and Penicillium spp. have been reported as contaminants on various cereal grains around the world, although relatively few species dominate in any given location. Efforts to mitigate the risk of fungal contamination and OTA accumulation can be made pre- and postharvest.

McCarthy, Susan et al. Scombrotoxin fish poisoning (SFP), also known as histamine (Hst) poisoning, has been associated with consumption of scombroid-type fish, including tuna and tuna fish products. Preparation of commercial tuna salad contaminated with Hst-producing bacteria (HPB), combined with time-temperature abuse, can present a food safety hazard. A potential source of HPB is raw ingredients, such as celery and onions.

Bjornsdottir-Butler, Kristin et al. Recent developments in detection and enumeration of histamine-producing bacteria (HPB) have created powerful molecular-based tools to better understand the presence of spoilage bacteria and conditions, resulting in increased risk of scombrotoxin fish poisoning. We examined 235 scombrotoxin-forming fish from the Gulf of Mexico for the presence of high HPB. Photobacterium damselae subsp.

Mei, Jun et al. The objective of this work was to evaluate the effectiveness of antimicrobial edible coatings to improve the quality of Bod ljong cheese throughout 25 days of storage. Coatings were prepared using chitosan, water chestnut starch, and glycerol as a base matrix, together with several combinations of antimicrobial substances: Cornus officinalis fruit extract (COFE), pine needle essential oil (PNEO), and nisin.

Soares-Santos, Verónica et al. Enterococcus species are ubiquitous in nature, exist at high levels in food, and can cause severe diseases in humans. Thus, surveillance of enterococci harboring antibiotic resistance and virulence factors in food and food-related environments is needed. In the present study, 89 samples from food and food processing surfaces were collected in a cheese factory, a swine slaughterhouse, and a supermarket, and 132 Enterococcus isolates were recovered.

The objectives of study were to assess presence of Listeria monocytogenes, perform serotyping and investigate antibiotic resistance in raw milk and dairy products. A total of 210 milk and dairy products including white (n = 20) and kashar cheese (n = 20), ice cream (n = 20), butter (n = 20), cokelek (n = 10), kuymak (n = 10) and farm cheese (n = 10) were obtained from Samsun, Turkey.
