Cadmium is one of the most hazardous environmental pollutants for plants due to its mobility and high toxicity. One effective method that may be utilized to decrease heavy metal pollution in the soil is the use of nano-chelated iron. In the present study, lettuce plants were treated with four different concentrations of cadmium chloride, two different concentrations of nano-chelated iron, and six combinations of cadmium chloride+nano-chelated iron.

Milking methods have significant impacts on the microbiological composition, which could affect the quality of raw buffalo milk. Hence, the current study was conducted on the impact of milking methods on microorganisms in buffalo tank raw milk from 15 farms in Guangxi, China. The farms were divided into two groups based on the milking method: mechanical milking (MM, n = 6) and hand milking (HM, n = 9).

Bacillus cereus sensu stricto is a foodborne pathogen that causes food poisoning. Their spore and biofilm-forming abilities persist in various environments and foods. This study investigated the prevalence, virulence, antibiotic resistance, and genetic diversity of B. cereus s. s. strains isolated from various food samples. Of 179 samples, 22.34% were positive for B. cereus s. s., with significantly high detection rates in milk products and raw chicken meat.

A two‐level factorial design was used to evaluate the effect of food‐related stresses on the biofilm formation ability of Salmonella serotypes. Freezing time was the most important factor affecting biofilm formation response of Salmonella. Interaction of pH and heat was the most significant interactive effect on biofilm of S. typhi. Interaction of NaCl and cold showed the most significant effect on the biofilms of S. enteritidis and S. typhimurium.

Vibrio parahaemolyticus, an important food-borne pathogens found to be associated with seafoods and marine environs. It has been a topic of debate for many decades that most pathogens are known to enter a viable but nonculturable (VBNC) state under cold temperature and nutrient limited conditions. The present study examined the time required for the induction of VBNC state and the revival strategies of both the endemic O3:K6 and O1:K25 sporadic strains of V.

Mycotoxin contamination in agri-food systems has been a serious global concern over the past few decades. Corn is easily contaminated by Ochratoxin A (OTA) and Zearalenone (ZEN), which seriously threaten the survival and health of humans and animals. Herein, a rapid and sensitive method of OTA and ZEN dual quantum dots (QDs) fluorescence immunochromatographic test strip was established in this study. OTA and ZEN fluorescence probes were prepared by carbodiimide.

Multidrug-resistant (MDR) Staphylococcus aureus has been increasingly isolated from pigs and people in close contact with them, especially livestock-associated methicillin-resistant S. aureus (LA-MRSA). In this cross-sectional study, we investigated S. aureus colonization in pigs and farm workers, their resistance profile, and genetic background to estimate interspecies transmission potential within farms from Rio de Janeiro state, Brazil, between 2014 and 2019.

Abstract BACKGROUND Worldwide, vegan and vegetarian lifestyles, as well as food allergies and intolerance (e.g. lactose intolerance and milk protein allergy) demand the development of alternatives to dairy‐based probiotic foods. In the present study, probiotic Lacticaseibacillus casei CECT 9104 was added to alginate‐based edible coatings enriched with inulin and oligofructose and applied to fresh‐cut apple.

Crayfish (Procambarus clarkii) are economically important freshwater crustaceans. With the growth of the crayfish industry, the associated food-safety risks should be seriously considered. Although Vibrio parahaemolyticus is commonly recognized as a halophilic foodborne pathogen associated with seafood, it has been found to be a major pathogen in crayfish-associated food poisoning cases. In this study, the V.

Contamination of poultry products by Salmonella enterica serovar Typhimurium (STm) is a major cause of foodborne infections and outbreaks. This study aimed to assess the diversity and antimicrobial resistance (AMR) carriage of STm in three chicken processing plants using genomic sequencing. It also aimed to investigate whether any particular strain types were associated with cases of human illness.

Shiga toxin-producing and Enteropathogenic Escherichia coli are foodborne pathogens commonly associated with diarrheal disease in humans. This study investigated the presence of STEC and EPEC in 771 dairy cattle fecal samples which were collected from 5 abattoirs and 9 dairy farms in South Africa. STEC and EPEC were detected, isolated and identified using culture and PCR.

Abstract The conclusions of the European Food Safety Authority (EFSA) following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State Poland and co‐rapporteur Member State Hungary for the pesticide active substance triclopyr (variant triclopyr‐butotyl) and the assessment of applications for maximum residue levels (MRLs) are reported.

This study found that co‐digesting probiotic‐coated cantaloupe with Natal plum or beetroot leaves enhances the bioaccessibility of anthocyanins and carotenoids and improves antioxidant activities. It also maintained viable cells of Lactiplantibacillus plantarum 75, providing insights into ingredient interactions. These results can inform food design and diet regulation for health‐conscious consumers.

Abstract Raman spectroscopy, a fast, non‐invasive, and label‐free optical technique, has significantly advanced plant and food studies and precision agriculture by providing detailed molecular insights into biological tissues. Utilizing the Raman scattering effect generates unique spectral fingerprints that comprehensively analyze tissue composition, concentration, and molecular structure.

This study investigated the impact of feeding 17% moringa leaf meal (MLM) on the ruminal and fecal microbial composition and body weight gain (BWG) performance of lambs (Ovis aries) and kids (Capra hircus). A total of n = 28 lambs (n = 14, no-moringa, n = 14, 17% moringa) and 24 kids (n = 12, no-moringa, n = 12, 17% moringa) were involved in the experiment and body weight was recorded fortnightly.
