A review of 46 studies finds antibiotic residues across several environmental systems in Ghana. The contamination may provide reservoirs for resistant bacteria and resistance genes, raising concerns about the spread of drug resistance.
A cocktail of two bacteria-killing viruses reduced Staphylococcus aureus in laboratory tests and in UHT milk. It also fully blocked production of one staphylococcal toxin in an in vitro assay, though the study did not test the approach in commercial dairy production or people.
In a West Texas field study, alfalfa irrigated with treated oil-and-gas wastewater grew similarly to alfalfa irrigated with groundwater. The water met most irrigation standards, but elevated strontium and the need to track long-term effects remain concerns.
