“…Since animal manure is the main fertilizer type in organic farming, where no chemical treatment against bacteria is allowed, it gives rise to concern about the possible contamination of produce with microbial pathogens such as Escherichia coli O157:H7, Salmonella spp., and Listeria monocytogenes. 21, 22 A key strategy used to reduce the concentration of enteric pathogens in manure is composting, the biological decomposition of organic matter by microorganisms under controlled conditions 23 . Compost can provide certain benefits to plants when applied to the soil.…”

Fresh produce is a generalized term for a group of farm-produced crops, including fruits and vegetables. Organic agriculture has been on the rise and attracting the attention of the food production sector, since it uses eco-agricultural principles that are ostensibly environmentally-friendly and provides products potentially free from the residues of agrochemicals. Organic farming practices such as the use of animal manure can however increase the risk of contamination by enteric pathogenic microorganisms and may consequently pose health risks. A number of scientific studies conducted in different countries have compared the microbiological quality of produce samples from organic and conventional production and results are contradictory. While some have reported greater microbial counts in fresh produce from organic production, other studies do not. This manuscript provides a brief review of the current knowledge and summarizes data on the occurrence of pathogenic microorganisms in vegetables from organic production.

“…Composting is a dynamic process where a wide variety of microbial populations, including bacteria, actinobacteria, and fungi play key roles in the biotransformation of organic substrates . Not only the hemicellulose but also the rigid cellulose can be degraded and used by microorganisms as sources of energy and carbon.…”

A composting method was applied to improve the processability of rice straw (RS) and its interfacial interaction with a biodegradable resin, hydrolyzed‐soy‐protein‐modified urea formaldehyde adhesives. The composted RS was characterized by fiber testing, Fourier transform infrared spectroscopy, thermogravimetry, differential scanning calorimetry, and scanning electron microscopy. We found that the particle size of RS was reduced from 0.6–2.0 to 0.2–0.6 mm. The cellulose content decreased, and the lignin content increased; unstable bonds were decomposed after composting. All of the results were beneficial for improving the plasticity of RS. Composted RS with inoculant exhibited a higher peak degradation temperature (352 °C) than the untreated RS (347 °C). The porous structure and tissue in RS were destroyed by the microorganism. The best bonding results were obtained by the composted RS with inoculant. Compared with untreated composites, the modulus of rupture, modulus of elasticity, and tensile strength of the composites were improved by 14.94, 25.36, and 27.21%, respectively. In addition, a mechanism of the structural changes of RS during composting was also proposed. The full biodegradable composites have potential applications in agriculture toward the achievement of sustainable development. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 44878.

“…Composting is due to the combined activity of a wide variety of microbial populations, and several physical and chemical factors related to one another govern the succession of the different environmental conditions appearing throughout the process (Moreno et al, 2013). Microbes play the key role in composting (Insam and de Bertoldi, 2007), though their importance has been often underestimated.…”
