Foodborne

Leptospires are thin, coiled, motile bacteria transmitted to humans by rats, domestic animals, and farm animals. Human exposure usually occurs via environmental exposure but can also occur secondary to direct interaction with animal urine, feces, blood, or tissue. Although unrelated to natural disasters and flooding, in 2003 and 2017, two major outbreaks of hepatitis A occurred. The first happened in Beaver County, Pennsylvania, and was traced back to contaminated green onions served in a Mexican restaurant. The second took place in San Diego and—due to limited sanitation— the risk was pronounced among members of the homeless population. Together these outbreaks resulted in hundreds of hospitalizations and several deaths.



Exposure to contaminated water may occur from drinking or household water or from recreational water. Symptoms of waterborne illness from ingested pathogens include diarrhea, fever, nausea and vomiting. As a result, the risk of exposure to water-related pathogens, chemicals, and algal toxins will increase in recreational and shellfish harvesting waters and in drinking water where treatment barriers break down . Ensuring universal access to water and sanitation, the major preventive action for preventing these diseases, is one of the United Nation's Sustainable Development Goals for 2030. Challenges include emerging pathogens resistant to conventional water treatment, chemical contaminants, identifying endemic as well as epidemic waterborne disease, and understanding linkages to the environment. Novel methods for studying waterborne diseases, such as satellite imaging and new mathematical tools, are providing new insights.

Although the immediate effects of Category 5 hurricanes are shocking, resulting in floodwaters carry more insidious threats such as waterborne disease. A review of 548 outbreaks dating back to 1900 showed that 51% of these outbreaks were preceded by heavy downpours. Amoebiasis, or amebiasis, refers to infection caused by the amoeba Entamoeba histolytica.

Changes in hydrology resulting from climate change are expected to alter releases of chemical contaminants into the Nation’s surface waters,226 with as-yet-unknown effects on seafood contamination. Specific health outcomes are determined by different exposure pathways and multiple other social and behavioral factors, some of which are also affected by climate (Figure 6.1). Thus, it is often not possible to quantitatively project future health outcomes from water-related illnesses under climate change (bottom box in Figure 6.1). Many waterborne illnesses are diarrheal diseases, including cryptosporidiosis and giardiasis.

In cases of severe disease, kidney dysfunction needs to be treated with short-term dialysis. It’s important to treat leptospirosis with antibiotics to prevent organ failure. Patients should be treated as soon as possible before organ failure occurs. Leptospirosis can be treated with a broad range of antibiotics, including, ceftriaxone, cefotaxime, or doxycycline.

This may result in sunken eyes, cold skin, decreased skin elasticity, and wrinkling of the hands and feet. Cholera is caused by a number of types of Vibrio cholerae, with some types producing more severe disease than others. It is spread mostly by water and food that has been contaminated with human feces containing the bacteria. Risk factors for the disease include poor sanitation, not enough clean drinking water, and poverty.

Over 286 million Americans get their tap water from a community water system . The US Environmental Protection Agency regulates drinking water quality in public water systems and sets maximum concentration levels for water chemicals and pollutants. There are many parts in the world where waterborne diseases are rampant, deadly, and knowledge about prevention is not widely available.

Please contact the Minnesota Department of Health if you suspect you have a foodborne or waterborne illness. MDH will relay the necessary information to the appropriate local health authorities. Information about waterborne illness outbreaks, including detection and investigation in Minnesota. There is a lot you can do to enjoy water safely – whether water crisis you are swimming in it or drinking it. Symptoms and causes of waterborne illnesses and links to disease-specific information.

Specimen sites provide insight into the type of infections cases may have experienced. Cholera is another waterborne disease, caused by bacteria, that spawns epidemic health problems in much of the developing world—especially in Asia and Africa. Cholera can cause deadly diarrhea and, though many people survive infection, it can be a particularly dangerous disease for the malnourished. Serious outbreaks of giardiasis and cryptosporidiosis have occurred in cities with excellent water-treatment facilities and are of major concern in the water industry. Therefore, every effort must be made to minimize human contact with reclaimed water that may contain any of these pathogens. Of particular concern is the possibility of pathogens being carried in aerosols emitted by spray irrigation inasmuch as aerosols in the 2–5mm size are primarily removed in the respiratory tract.
