Abstract Purpose Organic wastes for agricultural use represents a real agronomic interest but also a risk for public and animal health. Actinomycetes present a potential source of bioactive compounds with multiple applications. Methods Among the 88 isolates of actinomycetes obtained from different samples, we selected a strain identified, thanks to macro- and microscopic characters, as Streptomyces sp. SCM21. This strain showed these potentialities to produce antibacterial metabolites against the pathogenic bacteria tested (S. aureus, B. cereus and S. enteritidis) when cultivated in liquid and solid fermentation. Solid-state fermentation was conducted using sewage sludge as substrate. Results This is the first time that sewage sludge has been used to produce antibacterial metabolites by a strain of actinomycetes in solid-state fermentation. In addition, solid-state fermentation moistened with distilled water gave better antibacterial activity with good sporulation of Streptomyces sp. CSM21. Conclusion The product of solid-state fermentation can be used in the management of contaminated waste to control pathogenic bacteria.

Microbial Efficiency

Recycling waste into new materials and energy is becoming a major challenge in the context of the future circular economy, calling for advanced methods of waste treatment. For instance, microbially-mediated anaerobic digestion is widely used for conversion of sewage sludge into biomethane, fertilizers and other products, yet the efficiency of microbial digestion is limited by the occurrence of antibiotics in sludges, originating from drug consumption for human and animal health. Here we present antibiotic levels in Chinese wastewater, then we review the effects of antibiotics on hydrolysis, acidogenesis and methanogenesis, with focus on macrolides, tetracyclines, β-lactams and antibiotic mixtures. We detail effects of antibiotics on fermentative bacteria and methanogenic archaea. Most results display adverse effects of antibiotics on anaerobic digestion, yet some antibiotics promote hydrolysis, acidogenesis and methanogenesis.

Agricultural Use

Different types of sewage sludge produced during wastewater treatment and after storage of up to 5 years were analyzed for both virus and parasite eggs. Among the 145 samples examined, 87.6 % were positive for either Nematode and/or Cestode eggs. Anaerobic digestion of the sludge had little influence on the numbers of helminth eggs while conditioning with lime plus ferric chloride reduced the egg recovery. Helminth eggs were found in sludge samples stored for 1–2 or 3 years, but none were found in samples stored for 4 years or more. None of the Ascaris eggs tested were viable. Out of the 57 sludge samples examined for virus, all the biological sludges contained enterovirus, while only 44 % of the digested sludge samples and 10 % of the semi-dehydrated and conditioned (lime plus ferric chloride) sludge samples were positive for enterovirus. No virus were found in stored sludge. Epidemiological studies are necessary in order to determine any risks presented to public and animal health by the agricultural use of the sewage sludge.

SummaryFifteen British Friesian steers were reared using grain and forages which had been grown on land which has had a long history of use for disposal of sewage sludges. The food consumption was recorded and samples of feedingstuffs analysed for Cd, Cr, Cu, Ni and Zn. The various components used in compounding the feedingstuffs were also analysed. After about 13 months the animals were slaughtered and samples of various organs and tissues obtained for analysis.The majority of the Cd, Cr, Cu and Zn came from sources other than uptake into plants. The largest single contributor was the high phosphate mineral supplement. No animal health problem due to the feed regime was encountered. Concentrations of cadmium in liver and kidney were slightly higher than average. Muscle cadmium concentrations of Cr, Cu, Pb, Ni and Zn were within the range of published values.

SUMMARYSamples of sewage, sewage sludge and sewage effluent from one or more of four sewage treatment plants were examined for the presence ofLeptospira, Mycobacterium, Escherichia coli, Brucella abortusandBacillus anthracis. Brucella abortusandBacillus anthraciswere not isolated. Eleven strains ofE. colipotentially enteropathogenic for calves or piglets, eight pathogenic strains ofMycobacteriumand one pathogenicLeptospirastrain were isolated from 101, 189 and 189 samples respectively.Sewage sludge is not considered to play a major part in the epidemiology of disease caused by these organisms.

COVID 19 has raised the profile of biosecurity. However, biosecurity is not only about protecting human life. This issue brings together mini-reviews examining recent developments and thinking around some of the tools, behaviours and concepts around biosecurity. They illustrate the multi-disciplinary nature of the subject, demonstrating the interface between research and policy. Biosecurity practices aim to prevent the spread of harmful organisms; recognising that 2020 is the International Year of Plant Health, several focus on plant biosecurity although invasive species and animal health concerns are also captured. The reviews show progress in developing early warning systems and that plant protection organisations are increasingly using tools that compare multiple pest threats to prioritise responses. The bespoke modelling of threats can inform risk management responses and synergies between meteorology and biosecurity provide opportunities for increased collaboration. There is scope to develop more generic models, increasing their accessibility to policy makers. Recent research can improve pest surveillance programs accounting for real-world constraints. Social science examining individual farmer behaviours has informed biosecurity policy; taking a broader socio-cultural approach to better understand farming networks has the potential to change behaviours in a new way. When encouraging public recreationists to adopt positive biosecurity behaviours communications must align with their values. Bringing together the human, animal, plant and environmental health sectors to address biosecurity risks in a common and systematic manner within the One Biosecurity concept can be achieved through multi-disciplinary working involving the life, physical and social sciences with the support of legislative bodies and the public.
