Colibacillosis (E. coli) in geese: symptoms, prevention and treatment records
Pathogenic strains of Escherichia coli usually attack geese secondarily, when immunity is weakened. In goslings they most often cause yolk sac and navel infection and septicaemia. Learn how to recognise the disease, how to prevent it, and how to keep compliant treatment records.

What is colibacillosis in geese?
Colibacillosis is a bacterial disease caused by pathogenic strains of Escherichia coli — known in poultry as APEC (avian pathogenic E. coli). This bacterium normally lives in the gut of healthy birds, so in geese it usually attacks secondarily — when immunity is weakened by another disease, stress, poor housing climate or high bacterial pressure in the environment. It is most dangerous in goslings, where systemic infection develops easily. In older birds it more often runs as serositis (inflammation of the serous membranes). More about the species: Goose farming.
What are the symptoms in goslings?
In the youngest goslings two forms dominate: yolk sac and navel infection (omphalitis — infection of the unhealed navel and unabsorbed yolk sac) and septicaemia, a generalised blood infection. The signs are non-specific: goslings are apathetic and listless, take little feed and water, huddle near the heat source, have ruffled down and often a swollen, hard or reddened belly. The navel may be wet, unhealed or foul-smelling. In the septicaemic form, deaths rise quickly in the first days of life, especially when hatchery hygiene was poor. Overview of other diseases: Goose diseases.
How does the disease run in older geese?
In reared and adult geese, colibacillosis more often takes a chronic form — as serositis. The bacterium then settles on the pericardium (the membrane around the heart), the liver capsule and the air sacs, forming the characteristic fibrinous deposits seen at post-mortem. The birds grow more slowly, are less vigorous, use feed less efficiently, and some die. This form usually develops on a background of earlier immune weakening — after a viral disease, with poor ventilation, or with a dusty and damp house. The same applies to colibacillosis in other poultry species: Poultry colibacillosis.
Why do litter and water matter so much?
Geese are water birds — they readily use drinkers and outdoor ranges near water, which makes them very prone to soiling and wetting the litter. Wet, dirty litter is an ideal environment for E. coli to multiply, and high bacterial pressure in the surroundings raises the risk of infection, especially in young birds. That is why keeping the litter dry and friable — despite access to water — is one of the most important parts of prevention. More on litter management: Poultry house litter — management.
Colibacillosis and other flock health problems
Colibacillosis is rarely a primary disease — it most often appears as a complication. So with recurring E. coli infections it is always worth looking for the underlying cause: errors in the housing climate, dampness, viral infection or gaps in biosecurity. Effectively reducing colibacillosis means putting the whole rearing environment and hatchery hygiene in order, not just giving antibiotics. Whenever disease is suspected or results deteriorate, always consult a veterinarian. Full symptom overview: Poultry diseases — symptom table.
How colibacillosis affects a goose flock
Each of these signals should prompt the farmer to consult a veterinarian and establish the cause.
Unhealed, foul-smelling navel
In goslings, infection of the unhealed navel and yolk sac (omphalitis) produces a wet, reddened or foul-smelling navel and a swollen, hard belly. This is the most common form of the disease in the youngest birds.
Apathy and listlessness in goslings
Sick goslings are sluggish, have ruffled down, huddle near the heat source and barely approach feed and water. Watching flock behaviour allows early detection of the problem.
Rapidly rising mortality
In the septicaemic form (generalised blood infection), gosling deaths can rise sharply in the first days of life — especially with poor hatchery hygiene and dirty litter.
Slower growth and non-uniformity
In older birds, chronic colibacillosis shows as poorer feed conversion, slower growth and large weight differences between birds in the flock.
Fibrinous deposits on organs
Serositis — inflammation of the pericardium, liver capsule and air sacs — produces the characteristic fibrinous deposits at post-mortem. This is the typical picture of the chronic form in geese.
Recurrence after another disease
Because E. coli usually attacks secondarily, colibacillosis often appears after a viral infection, under stress or with a poor housing climate. Recurrences point to an unresolved underlying cause.
How to prevent colibacillosis and how to act when disease is suspected
Effective prevention rests on hatchery hygiene, dry litter, a good housing climate and biosecurity — treatment only under veterinary supervision.
Dry litter despite access to water
Keeping litter dry and friable lowers bacterial pressure. The keys are leak-proof drinkers, good ventilation, dry ranges and regular topping-up or replacement of wet litter. Details: Poultry house litter.
Hatchery hygiene and gosling quality
Many infections begin in the hatchery — through dirty hatching eggs or contaminated equipment. Source goslings from trusted suppliers with good hatchery hygiene, and check that chicks have a properly healed navel.
A good brooding climate
The right temperature in the brooding area, good draught-free ventilation and low dust reduce the stress and immune weakening that open the door to E. coli. Housing requirements: Housing requirements for geese.
Farm biosecurity
Limiting the entry and spread of pathogens — quarantine, cleaning and disinfection between batches, control of entries and equipment — lowers bacterial pressure. More: Poultry farm biosecurity.
Treatment based on susceptibility testing
Antibiotic treatment is decided solely by a veterinarian — prudently and ideally based on an antibiogram (susceptibility test), because E. coli strains can be resistant. Match the drug, dose and duration to the recommendation. Expert help: Veterinarian.
Treatment records and withdrawal
Every administration of a veterinary medicine must be recorded: date, drug, dose, route of administration, withdrawal period before slaughter. DlaFerm.pl lets you keep these records digitally. More: Treatment records and drug withdrawal.
Frequently asked questions about colibacillosis in geese
What is colibacillosis in geese?add
It is a bacterial disease caused by pathogenic strains of E. coli (APEC). In geese it usually attacks secondarily, when immunity is weakened. In goslings it most often causes yolk sac and navel infection and septicaemia, while in older birds it causes serositis (inflammation of the serous membranes).
Why are goslings most affected?add
Goslings have an immature immune system and an unhealed navel through which infection enters easily. With poor hatchery hygiene and wet, dirty litter the bacterial pressure is high, so yolk sac and navel infection and septicaemia develop. That is why the first days of life are the most important.
How are water and ranges linked to the disease?add
Geese are water birds and very easily wet and soil the litter near drinkers and on ranges close to water. Wet, dirty litter favours E. coli multiplication and raises bacterial pressure. Keeping litter and ranges dry despite access to water is one of the most important parts of prevention.
How is colibacillosis treated in geese?add
Treatment is an antibiotic chosen by a veterinarian — prudently and ideally based on an antibiogram, because E. coli strains can be resistant. Treatment alone is not enough: the underlying cause must be removed by improving hygiene, the housing climate and litter dryness. Every dose must be recorded with the withdrawal period observed.
Is there an E. coli vaccine for geese?add
The availability and usefulness of vaccination depend on the flock situation and the veterinarian’s decision. In practice, prevention in geese still rests on hatchery hygiene, dry litter, a good housing climate and biosecurity. Any vaccination programme is always decided by the veterinarian caring for the farm.
