#LAKE MICHIGAN SWIMMERS ITCH CODE#

Each sampling event shall consist of three or more samples taken at representative locations within a defined sampling area. Compliance shall be based on the geometric mean of all individual samples taken during five or more sampling events representatively spread over a 30-day period. coli) per 100 milliliters (ml), as a 30-day geometric mean. All waters of the state protected for total body contact recreation shall not contain more than 130 Escherichia coli (E.Water results are verified to determine compliance to the rule, which states the following:

#LAKE MICHIGAN SWIMMERS ITCH CODE#

coli standards for swimming are provided in the Michigan Public Health Code and Rule 323.1062(1) of the Part 4 Water Quality Standards (as promulgated pursuant to Part 31 of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended).

coli bacteria suggests that other harmful, disease-causing pathogens may also be present.Į. Several factors can influence bacteria counts such as land use and land development, weather conditions, wind direction, air and water temperatures, season, stormwater inputs (runoff), wildlife concentrations, and the number and frequency of bathers.

The results of bathing beaches are indicative to that specific area, not the lake as a whole. The following bathing beaches are monitored once each week (typically between Memorial Day and Labor Day):Ĭampbell Lake, Robert Morris Township Park To protect public exposure to surface water that does not meet Michigan's Water Quality Standards.To determine compliance to Michigan's Water Quality Standards for total body contact recreation.To assure a safe and healthy recreational experience at Kalamazoo County public bathing beaches.Current bacteriological results and information about statewide beach monitoring can be found at the Michigan Department of Environment, Great Lakes, and Energy beach monitoring website. No Partial Body Contact: refrain from activities involving direct contact to surface water including swimming, wading and fishing.Įnvironmental Health monitors nine Kalamazoo County bathing beaches for E. No Total Body Contact: refrain from activities involving complete submergence, particularly immersion of the head, into surface water that would involve risk of ingesting water. There are no current advisories at this time. For further information regarding publication in the journal, contact the editorial office at For information about membership in ASP, contact the society. Membership in ASP includes receipt of the Journal of Parasitology, a quarterly Newsletter, and abstracts for the annual meetings students can join at a much reduced rate. Institutional subscriptions are available. The journal is printed at Allen Press in Lawrence, Kansas, in six issues per year. Most of the emphasis rests with eukaryotic parasites, although vectors for prokaryotic organisms and viruses are also included. The journal focuses on general parasitology, as well as parasites of medical, veterinary, and economic importance. It has been in print continuously since 1914, when it was founded by Henry Baldwin Ward. The Journal of Parasitology is the official publication of the American Society of Parasitologists (ASP). Study designs that combine epidemiologic and biological data will simultaneously inform public health education and biological control programs. More studies of human incidence and severity are needed to convince public health agencies to address this problem at recreational lakes. In sum, onset and severity of swimmer's itch are affected by how people interact with the lake, not by their demographic features. Age and gender had no effect on incidence or severity. Episode severity increased with more time in the water and at the same locations. Probability of an episode increased with more days of water use and at locations with onshore winds. Incidence of swimmer's itch was 6.8 episodes per 100 water-exposure days. Minutes spent in the water, minutes in shallow water, location, time of day, preventive action, age, and gender were recorded for all residents and guests. Daily diaries about water exposures and swimmer's itch symptoms were completed by 40 riparian households at Douglas Lake, Michigan, for July 2000. This epidemiologic study reports incidence, severity, and risk factors of swimmer's itch (cercarial dermatitis).
