Recent evidence we have conducted this year further supports this conclusion. stagnicolae, to swimmer’s itch cases on Black Lake. szidati means that these parasite species are also cycling on Black Lake, and likely contributing, albeit to a much lesser extent than T. The verified presence of avian schistosomatid C and T. We'll be attentive to this issue in 2022.Īs we’ve made clear in the past, it’s impossible to completely eradicate swimmer’s itch on any lake. This species has never been detected in northern Michigan lakes before. Unfortunately, a new species that uses mallard ducks as the host was detected. ![]() Remember that the actions that we take in 2021 will affect our measures in 2022, so we are optimistic for improvement this year. We don't have a baseline comparison for that measure, but will have it for 2022. 19 cases of Swimmer's Itch were reported on Eyes on the Lake in 2021.
