The purpose of this study was to ascertain industrial noise pollution and its effects on the hearing capabilities of workers. The procedure adopted included noise measurements, otoscopy, audiometric evaluation and assessment of medical history. The results showed that noise levels in corn mills and saw mills exceed 85dBA. The average noise level measured in the printing industry was 85dBA. It was also found that 23 %, 20 % and 7.9 % of workers in corn mills, saw mills and the printing industry have evidence of noise-induced hearing loss (NIHL). A highly significant correlation was found between noise exposure level, duration of exposure and the development of NIHL in corm mills and saw mills but not in the printers. Hearing - impairment was also observed at the speech frequencies among some of the workers exposed to hazardous noise. These findings suggest that more specific intervention is required to protect workers exposed to such hazards at the work places employed in this study.

This study aimed to examine the nutritional diversity of distillers' co-products in pigs. Two distinct databases were used in this study. The first was compiled through a systematic review of previous scientific publications that have evaluated the chemical composition and nutritional availability of these ingredients for pigs.

Corn wet milling (CWM) and corn starch flash drying processing conditions reduce undesirable microorganisms, such as Salmonella. Finished products are historically safe, with intrinsic properties such as low water activity inhibiting microbial growth. Corn processors could use quantified levels of reduction in this study of Salmonella surrogate Enterococcus faecium (E.

The consumption of agricultural products contaminated with mycotoxins poses a significant threat to the health of both humans and animals. Maize frequently becomes contaminated with toxic fungi while it is still growing in the field. Therefore, more proactive measures should be implemented to reduce mycotoxin levels during the storage and processing of maize after harvest.

Article Synopsis
- - This study investigates how ball milling affects the properties and interactions of high amylose corn starch (HACS) and ferulic acid (FA) complexes, using density functional theory (DFT) calculations to analyze their structure and digestion qualities.
- - Results reveal that ball milling reduces the molecular weight of HACS, enhances the complexation with FA, increases its relative crystallinity by 11.74%, and improves short-range ordering, resulting in a more compact V-type structure.
- - The study finds that intermolecular interactions in the HACS-FA complexes are primarily driven by hydrophobic forces, hydrogen bonding, and van der Waals forces, suggesting a novel approach for efficiently preparing these complexes.
Estimating food consumption, micronutrient intake and the contribution of large-scale food fortification to micronutrient adequacy in Tanzania.

Objective: To assess the potential contribution of large-scale food fortification (LSFF) towards meeting dietary micronutrient requirements in Tanzania.
Design: We used household food consumption data from the National Panel Survey 2014-15 to estimate fortifiable food vehicle coverage and consumption (standardised using the adult female equivalent approach) and the prevalence at risk of inadequate apparent intake of five micronutrients included in Tanzania's fortification legislation. We modelled four LSFF scenarios: no fortification, status quo (i.
