Abstract

BACKGROUND: Many human infections are transmitted through contact with animals (zoonoses), including household pets. Despite this concern, there is limited knowledge of the public's pet husbandry and infection control practices. The objective of this study was to characterize zoonotic disease related-husbandry and infection preventive practices in pet-owning households in Ontario, Canada. METHODS: A self-administered questionnaire was distributed to individuals at two multi-physician clinics in Waterloo, Ontario, Canada during 2010. One adult from each household was invited to participate in the study. RESULTS: Four hundred one pet-owners completed the questionnaire. Households reported ownership of dogs (68%), cats (48%), fish (13%), exotic mammals (7%), such as hamsters, and reptiles and birds (each 6%). Across all species, individuals at higher risk of infections (i.e. < 5 yrs, ≥ 65 yrs, immunocompromised) were often (46-57%) present in households. Children < 16 yrs of age had close pet contact, as households reported dogs (13%) and cats (30%) usually slept in a child's bed and dogs often licked a child's face (24%). Household husbandry practices that increase zoonotic disease risk were frequently identified; some fed high-risk foods (i.e. raw eggs, raw meat, or raw animal product treats) to their dogs (28%) or cats (3%); 14% of reptile-owning households allowed the pet to roam through the kitchen or washed it in the kitchen sink. Reported hand washing by children was high for all species (> 76% washed hands sometimes or greater after touching the pet, its feces, or housing), although fewer reported children always washed their hands (3-57%; by species). With a few exceptions, practices were not associated with the presence of higher risk members in the household or recall of having previously received zoonotic disease education. CONCLUSIONS: The results suggest there is a need for education on zoonotic disease prevention practices for pet-owning households with individuals at higher risk of infection and those with high-risk species (e.g., reptiles). Further research is needed to determine the role of education in altering higher risk pet practices.

  • Companion animals are a potential source for more than 70 human diseases.

    “Through these mechanisms, companion animals are a potential source for more than 70 human diseases, 2,5,6”

    From Reducing the risk of pet-associated zoonotic infections (2015) · cites this paper as [2]

    The Background states that more than 70 pathogens of companion animals are known to be transmissible to people. That supports companion animals as a potential source of human infection, but it does not establish a count of more than 70 distinct human diseases. (LLM, conf=0.84)

  • Pet ownership and the species involved in households with immunocompromised children and children aged less than 5 years are similar to households with immunocompetent children.

    “Pet ownership, and the species involved, in households with immunocompromised children and children aged less than 5 years are similar to households with immunocompetent children. 2,3”

    From Reducing the risk of pet-associated zoonotic infections (2015) · cites this paper as [2]

    The Discussion reports that households with higher-risk individuals owned pets across all animal species studied, including reptiles. But the paper groups children under 5 with older and immunocompromised people; it does not establish that pet ownership rates or species are similar specifically between households with immunocompromised or under-5 children and households with immunocompetent children. Its reported similarity concerns husbandry and infection-control practices, not ownership. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The risk of Toxocara exposure is highest after contact with soil contaminated with waste from untreated or stray animals, such as in sandboxes, gardens, or playing fields.

    “Because most household pets are regularly dewormed and larvae require two to three weeks after being passed in feces to become infective, the risk of exposure is highest after contact with soil contaminated with waste from untreated or stray animals, such as in sandboxes, gardens or playing fields. 2,26”

    From Reducing the risk of pet-associated zoonotic infections (2015) · cites this paper as [2]

    The Results (Dog-owning households; page unavailable) report that children played where household dogs defecated, supporting the possibility of exposure in feces-contaminated play areas. The paper does not establish that Toxocara exposure is highest in soil contaminated by untreated or stray animals, or identify sandboxes, gardens, and playing fields as the highest-risk settings. Its Results (Cat-owning households; page unavailable) report endoparasite prevention for all cats in only 42% of responding households, rather than establishing that most household pets are regularly dewormed. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • Children (notably aged 3-5 years) and some people with developmental disabilities may have suboptimal hygiene practices or higher risk contacts with animals that further increase risk.

    “In addition, children (notably those aged 3-5 yr) and some people with developmental disabilities may have suboptimal hygiene practices or higher risk contacts with animals that further increase risk. 2”

    From Reducing the risk of pet-associated zoonotic infections (2015) · cites this paper as [2]

    The Discussion (page unavailable) identifies children under 5 as at greater known or presumed risk and reports close pet contact, including face licking. The Results (page unavailable) report that some children did not always wash their hands. The paper does not single out ages 3–5 or address people with developmental disabilities. (LLM, conf=0.86)

  • Pet ownership practices and the frequency of animal contact in immunocompromised/high-risk patients are typically similar to those seen in the general public.

    “However, pet ownership practices and the frequency of animal contact in this group are typically similar to those seen in the general public. 2,3”

    From Reducing the risk of pet-associated zoonotic infections (2015) · cites this paper as [2]

    The Abstract Results and Discussion (pages not provided) report that, with a few exceptions, husbandry and infection-control practices did not differ between pet-owning households with and without higher-risk members. The paper does not establish that immunocompromised patients themselves had a similar frequency of animal contact to the general public; its comparisons concern households, and some child-contact practices differed by age. (LLM, conf=0.82)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
