Study Finds Cow Manure Contaminates WI Wells and Causes Cryptosporidium

A new federal study released today has found that it's possible that cow manure contaminates wells in a county in Wisconsin and causes Cryptosporidium illnesses. The researchers looked at private wells in Kewaunee County, which is in northeastern Wisconsin on Lake Michigan. The county has a population of about 20,000 people, but there are 100,000 head of cattle in the area. About 12,000 residents get their water from private wells. The study used data from a countrywide pathogen occurrence study that lasted for a year. The scientist put the numbers into a quantitative microbial risk assessment to predict the cases of acute gastrointestinal illness linked to those wells. The results found that private well contamination could cause more than 300 acute gastrointestinal illnesses per … [Read more...]

After Severe Weather, What Does a Boil Water Notice Mean?

Cryptosporidium Outbreaks Have Increased by 13% Year Over Year

According to a study published in the CDC's Morbidity and Mortality Weekly Report, cryptosporidium outbreaks in 40 states and Puerto Rico have increased by 13% year over year in this country. Leading causes for this illness include swallowing contaminated water in pools or water playgrounds, contact with infected cattle, and contact with infected people in childcare settings. From 2009 to 2017, there were 444 cryptosporidiosis outbreaks from 40 states and Puerto Rico that caused 7,465 illnesses. Twenty-two of those outbreaks were associated with unpasteurized milk and apple cider. And the report states that the outbreaks likely underestimate the actual number of cryptosporidiosis outbreaks, and the reported number of cases "likely underestimate the actual magnitude of individual … [Read more...]

E. coli and Cryptosporidium Cases Rise in Michigan

Cases of E. coli and Cryptosporidium increased this summer in two counties in Michigan, according to the Health Department. Jennifer Morse, medical director of three regional health departments in that state said in a statement, "These increases are concerning because the resulting illness can be life-threatening. With the investigations that have been completed thus far, the major source seems to be coming from farm animals." These illnesses occurred in Mecosta and Newaygo counties in Michigan. This is important information, since we are approaching the time when many farms open their gates to tourism. Apple picking season is here. Deadly food poisoning outbreaks linked to farms have increased in the past few years. In fact, in 2013, an E. coli O157:H7 outbreak at Dehn's Pumpkins in … [Read more...]
