- There are an estimated 3.5 - 5 million resident geese in the U.S. - geese that no longer follow the standard migratory patterns of most Canada geese
- The average adult Canada goose eats 3lbs of grass every day, damaging up to 5 square feet of turf in the process
- Each adult Canada goose drops 1.5lbs of effluent every day
Geese and E. coli
- 2 studies characterized E. coli in goose feces found in urban environments
- In a Fort Collins, CO study, the overall prevalence of pathogenic E. coli in Canada goose feces was found to be 25% (Kullas, et al. 2002)
- 4 general potentially pathogenic E. coli and 2 virulence factors were identified. 1 virulence factor is known to produce severe diarrhea, while the other is associated as a causative agent of infantile meningitis
- Researchers also quantified the amount of feces in parks, estimating that a person taking a 1-mile walk in a park was likely to physically come in contact, on the bottom of his or her shoes, with 4-8 piles of feces that contained virulence determinants
