Awareness is growing around food safety culture in the UK food industry, with significant impacts on the finances and reputation of food businesses being recognised. This article outlines the five-step approach that should be taken to embed a positive food safety culture in the industry.

Listeria monocytogenes was linked to an outbreak of foodborne illness associated with in-process contaminated ice cream in the United States from 2010 to 2015 that sickened 10 individuals and led to 3 deaths. Ice cream obtained from the outbreak was used in this study to examine the population dynamics of L. monocytogenes as in-process contaminants compared with artificially inoculated cells.

Intermediate-salinity environments are distributed around the world. Here, we present a snapshot characterization of two Peruvian thalassohaline environments at high altitude, Maras and Acos, which provide an excellent opportunity to increase our understanding of these ecosystems.

The Fusarium mycotoxin deoxynivalenol (DON) contaminates animal feed worldwide. In vivo, DON modifies the cellular protein synthesis, thereby also affecting the immune system. However, the functional consequences of this are still ill-defined. In this study, peripheral blood mononuclear cells from healthy pigs were incubated with different DON concentrations in the presence of Concanavalin A (ConA), a plant-derived polyclonal T-cell stimulant.

In this paper, two varieties of potato (Ranger Russet and Van Gogh) with various slice size (9, 6, and 3 mm) were deep fried at various temperatures and time combinations (150, 170, and 190°C for 10, 20, and 30 min) and contents and kinetic parameters of acrylamide were investigated. Formation of acrylamide for both potato varieties followed zero‐order reaction models. As the frying temperature and time increased, formation of acrylamide increased in both potato varieties.

This study focused on the effects of biochar (BC) application on soil chemical properties and mobilization of cadmium (Cd) and lead (Pb) in the paddy soil. BC was applied at the rate of 0, 10, 20 and 40 t ha‐1, respectively. BC application caused significant increase in soil organic carbon contents (SOC), pH, nitrate nitrogen (NO3‐‐N), and available phosphorus contents (AP) in the top and subsurface soil, while SOC contents in the subsurface soil decreased with increasing rate of BC.

Both cadmium (Cd) and lead (Pb) are associated with bone health, but studies exploring the effects of Cd and Pb co‐exposure on bone health are rare. This study aimed to assess the interactive effects of Cd and Pb co‐exposure on bone health. In total, 799 participants, living in the targeted areas (located in southwestern China) for more than 15 years, aged 40‐75 years, and subsisted on homegrown rice and vegetables were investigated.

ABSTRACT BACKGROUND The low cost of aminoglycoside (AMG) antibiotics facilitates their excessive use in animal husbandry and agriculture sector. This scenario has led to the occurrence of residues in the food chain. After several years of AMGs use in antibacterial therapy, resistance to streptomycin has begun to appear. The method lacks AMG specificity previously reported against a single antibiotic and described as selective.

ABSTRACT In this paper the relationship between lipophilic grape seed proanthocyanidin (LGSP) and acrylamide formation in potato‐based products was investigated. The acrylamide, reducing sugar, asparagine, and 3‐aminopropionamide contents were determined by high performance liquid chromatography‐mass spectrometry (HPLC‐MS). Sensory evaluation was used to evaluate the quality of the products.

The present study was envisaged with an aim to determine the occurrence of antibiotic residues; enrofloxacin, oxytetracycline, penicillin G, sulphamethoxazole and chloramphenicol as well as mycotoxins; aflatoxin M1 and ochratoxin A in raw milk samples collected from individual animals from dairy farms located in 9 districts of Punjab, India. A total of 168 raw milk samples were collected and analysed using commercially available competitive Enzyme linked immunosorbent assay kits.

Salmonella causes illness in millions of people each year with severe cases resulting in death. Traditional detection methods are well established but are associated with disadvantages such as time or reoccurring sample cost. Hyperspectral microscope imaging (HMI) has shown potential as an early and rapid detection method, identifying bacteria based on spectral signatures unique to the microorganism. Bacteria undergo physiological changes when introduced to environmental stresses.

An automated optical biosensor-based immunoassay exploiting surface plasmon resonance detection for the quantitation of aflatoxin M1 (AFM1) in milk and milk powders is described. A monoclonal antibody and an immobilized protein–AFM1 conjugate are utilized in a simple inhibition format following aqueous extraction and immunoaffinity clean-up of the sample, thereby avoiding the need for signal amplification techniques.

Staphylococcus aureus is a bacterial pathogen that causes food poisoning, various infections, and sepsis. Effective strategies and new drugs are needed to control S. aureus associated infections due to the emergence and rapid dissemination of antibiotic resistance. In the present study, the antibacterial activity, potential mode of action, and applications of flavonoids from licorice were investigated.

Abstract

Background

Internet of Things (IoT) is growing exponentially and can become an enormous source of information. IoT has provided new opportunities in different domains but also challenges are apparent that must be addressed. Little attention has been paid to the potential use of IoT in the food safety domain and therefore the aim of this study was to fill this gap.

ABSTRACT

Helicobacter suis is a fastidious, Gram negative bacterium that colonizes the stomach of pigs and non-human primates. It has also been associated with gastric disease in humans.
