  text: <jats:p>food are discarded annually, with a worldwide total exceeding 1.3
    billion tonnes. A significant contributor to this issue are consumers throwing
    away still edible food due to the expiration of its best-before date. Best-before
    dates currently include large safety margins, but more precise and cost effective
    prediction techniques are required. To address this challenge, research was conducted
    on low-cost sensors and machine learning techniques were developed to predict
    the spoilage of fresh pizza. The findings indicate that combining a gas sensor,
    such as volatile organic compounds or carbon dioxide, with a random forest or
    extreme gradient boosting regressor can accurately predict the day of spoilage.
    This provides a more accurate and cost-efficient alternative to current best-before
    date determination methods, reducing food waste, saving resources, and improving
    food safety by reducing the risk of consumers consuming spoiled food.

  text: Ostrich meat is characterized by high nutritional value; however, it remains
    an exotic product in most countries worldwide. In Europe, only few data are available
    regarding its microbial contamination, prevalence of antimicrobial-resistant bacteria,
    and safety. Therefore, this study aimed to investigate the microbiological quality
    and safety of ostrich meat samples (n = 55), each from one animal, produced in
    Bavaria, Germany. The provided microbiological status of ostrich meat included
    mesophilic aerobic bacteria, Enterobacteria, and mesophilic yeast and molds. In
    terms of food safety, all meat samples were negative for Salmonella spp. and Trichinella
    spp. Additionally, meat samples and a further 30 stool samples from 30 individuals
    were investigated for Shiga toxin-producing Escherichia coli genes, with two meat
    samples that were qPCR-positive. Antimicrobial-resistant Enterobacteriaceae, Enterococcus
    faecalis, and Enterococcus faecium strains were from meat and stool samples also
    analyzed; 13 potentially resistant Enterobacteriaceae (meat samples) and 4 Enterococcus
    faecium (stool samples) were isolated, and their susceptibility against 29 and
    14 antimicrobials, respectively, was characterized. The results of this study
    provide an overview of microbial loads and food safety aspects that may be used
    as baseline data for the ostrich meat industry to improve their hygienic quality.
    However, the implementation of monitoring programs is recommended, and microbiological
    standards for ostrich meat production should be established.
