An instrument-free, integrated micro-platform for rapid and multiplexed detection of dairy adulteration in resource-limited environments
In this study, we introduced a fully integrated and portable microfluidic detection platform called Sector Self-Driving Microfluidics (SDM), designed to simultaneously detect eight common species-specific components in milk. SDM integrated nucleic acid extraction, purification, loop-mediated isothermal amplification (LAMP), and lateral flow strip (LFS) detection functions into a closed microfluidic system, enabling contamination-free visual detection. The SDM platform used a constant-temperature heating plate, powered by a mobile battery, eliminated the need for additional power support. The SDM platform achieved nucleic a...

Detection of risk areas in dairy powder processes: The development of thermophilic spore forming bacteria taking into account their growth limits
Int J Food Microbiol. 2024 Apr 22;418:110716. doi: 10.1016/j.ijfoodmicro.2024.110716. Online ahead of print.ABSTRACTAnoxybacillus flavithermus, Geobacillus stearothermophilus and Bacillus licheniformis are the main contaminants found in dairy powders. These spore-forming thermophilic bacteria, rarely detected in raw milk, persist, and grow during the milk powder manufacturing process. Moreover, in the form of spores, these species resist and concentrate in the powders during the processes. The aim of this study was to determine the stages of the dairy powder manufacturing processes that are favorable to the growth of such ...

Impact of memory bias in the dietary estimation of older adults measured through a food frequency questionnaire and weighed food records: A cross-sectional study in older adults and primary caregivers
CONCLUSION: the high correlation and high agreement between the amounts and frequencies of the food groups consumed as reported by the older adults and primary caregivers indicate that the information from both respondents is reliable.PMID:38666333 | DOI:10.20960/nh.04858 (Source: Nutricion Hospitalaria)

A method for estimating the outer exposure of dairy cows to deoxynivalenol (DON) and zearalenone (ZEN) as a precondition for risk assessment based on inner exposure with toxin residue levels in blood and urine as indicators
AbstractDON and ZEN residues in the blood and urine of dairy cows can be used to predict the outer exposure to DON and ZEN expressed per kilogram diet for a risk evaluation based on comparisons to critical dietary concentrations. This method was used to evaluate the exposure of dairy cows from 12 farms located in Brandenburg, Germany, fed rations with unknown DON and ZEN concentrations (N = 244). The corresponding diet concentrations predicted by different methods from analyzed blood and urine samples varied significantly amongst farms from 0 to 1.6 mg/kg for DON and 0 to 3.0 mg/kg for ZEN at a reference dry matter c...

CDC: H5N1 Bird Flu Confirmed in Person Exposed to Cattle
Highly pathogenic avian influenza A(H5N1), also known as H5N1 bird flu, has been circulating among birds and mammals for the past few years. This March, US officials detected it in dairy cattle in several states. Later that month, a farm worker who was exposed to dairy cattle in Texas tested positive for H5N1 bird flu, the US Centers for Disease Control and Prevention (CDC) announced in a health alert.

Correlation of udder thermogram and somatic cell counts as a tool for detection of subclinical mastitis in buffaloes
This study aimed to monitor the mammary health of 37 multiparous Murrah buffaloes through infrared thermography (IRT). Based on the California Mastitis Test (CMT) and milk somatic cell counts (SCC), buffaloes were grouped into healthy (H, n = 16), subclinical mastitis (SCM, n = 10), and clinical mastitis (CM, n = 11). Buffaloes were milked twice daily in the morning (5:00-6:00 AM) and evening (5:00-6:00 PM). Rectal temperature and respiratory rates were recorded, CMT was performed and thermal images of the mammary gland of all the buffaloes were taken before and after each milking. Milk samples were analysed after each mil...

Assessment of Genomic Diversity and Selective Pressures in Crossbred Dairy Cattle of Pakistan
This study aims to provide the first overview of the selective pressures on the genome of crossbred dairy cattle in Pakistan. A total of eighty-one crossbred, thirty-two HF and twenty-four Sahiwal cattle were genotyped, and additional SNP genotype data for HF and Sahiwal were collected from a public database to equate the sample size in each group. Within-breed selection signatures in crossbreds were investigated using the integrated haplotype score. Crossbreds were also compared to each of their parental breeds to discover between-population signatures of selection using two approaches: cross-population extended haplotype...
