Fresh manure is a safe, ready-to-use fertiliser you can spread straight onto the garden.
Refuted
Fresh manure isn't a ready-to-use fertiliser. It burns plants with ammonia and salts, and raw manure can carry harmful bacteria like E. coli and Salmonella — a real food-safety risk on vegetables. Compost or age it first, or keep raw manure well clear of the harvest (guidance sets months between spreading and picking). Well-rotted manure or finished compost is the safe version.
What is actually known
Manure is a genuinely good soil amendment — once it is composted or aged. Fresh ("hot") manure is not the same thing, and spreading it straight on is a real mistake for two separate reasons. It is high in ammonia and soluble salts, which burn roots and foliage. And raw manure can carry human pathogens — E. coli O157:H7, Salmonella, Listeria — which is a food-safety matter, not a preference: guidance for raw manure on food crops sets long intervals between application and harvest (commonly around 90 to 120 days depending on whether the edible part contacts the soil), or requires proper hot composting first. Compost it, age it, or keep it well away from the harvest window; do not treat fresh manure as a drop-in fertiliser.

fresh manure is high in ammonia and soluble salts that scorch plants; raw manure can carry human pathogens (E. coli O157:H7
Salmonella)
and food-safety guidance sets long pre-harvest intervals (roughly 90-120 days) or requires composting; extension and food-safety consensus
