Aug 29, 2022 · Climate change is impacting our global food system in a variety of direct and indirect ways and presenting new challenges to food safety and human health. Changes in temperature and precipitation can affect the distribution and survivability of pathogens that cause foodborne illnesses 1. Changes in climate can cause severe droughts or flooding.

Foodborne disease is a major concern in Canada and represents a significant climate change-related threat to public health. Climate variables, including temperature and precipitation patterns, extreme weather events and ocean warming and acidification, are known to exert significant, complicated and interrelated effects along the entire length of t...
Many of the recently observed climate changes have been unprecedented over the preceding decades to millenniaFootnote 1Footnote 2. The projected changes to climate variables in Canada, including temperature and precipitation metrics, are well-documentedFootnote 3. In particular, annual average air and water temperatures and precipitation are expect...
The climate variables that most influence foodborne illness are increased air temperature, water temperature and precipitationFootnote 13Footnote 14. These variables affect foodborne illness through three mechanisms: abundance, growth, range and survival of pathogens in crops, livestock and the environmentFootnote 22;human exposure factors, includi...
When the causative agent is identified, the five bacteria that account for over 90% of foodborne illnesses in Canada are norovirus, Clostridium perfringens, Campylobacter spp., Salmonella spp. and Bacillus cereus (Table 1)Footnote 6. Four of these pathogens have been shown to be influenced by climate variables. Given the projected changes to climat...
There are other less common foodborne infections that are likely to increase with climate change and add to the burden to personal and public health. Mycotoxins, produced by fungi growing in crops such as corn and cereal grains, proliferate with increased air temperature, humidity and precipitationFootnote 45. Increased temperature stress or altera...
The medical and public health systems as well as the public will need to prepare for the anticipated amplification in the rate of illness from known foodborne pathogens and the emergence of illness from either exotic or less well-known pathogens. Clinicians need to stay informed on foodborne illness trends to better recognize and diagnose cases and...
Climate change will increase the risks from existing and emerging foodborne diseases, primarily through increases in extreme events, increases in air and water temperatures, and changes to precipitation frequency and intensity. It is important to note, however, that these trends regarding foodborne illness and climate change involve complex systems...
BAS — Conception, analysis and data interpretation, writing and editingAF — Conception, writing and editingJun 6, 2024 · Climate change threatens public health by affecting the distribution and spread of food-borne diseases. Changes in temperature and precipitation patterns, shifting consumer behavior, and altered distributions of food-borne pathogens increase exposure risk for humans and animals.
Temperature, precipitation, and humidity are important factors that can influence the spread, reproduction, and survival of pathogens. Climate change affects these factors, resulting in higher air and water temperatures, increased precipitation, or ...
Examples of the Canadian food system’s components that may be vulnerable to disruption by climate change impacts are identified, followed by analysis of how key pathways of vulnerability can influence food security and human health.
Dec 9, 2021 · Changing environmental conditions facilitate the transmission of many water-borne, air-borne, food-borne and vector-borne pathogens 1, with potential knock-on effects on the burden of...
Jun 29, 2022 · Three main factors govern the spread of foodborne illness: 1) the abundance, growth, range and survival of pathogens in crops, livestock and the environment; 2) the transfer of these pathogens...
