MDHHS, MDARD remind Michiganders about risks of consuming raw (unpasteurized) milk and milk products

April 17, 2024

The Michigan Department of Health and Human Services (MDHHS) and Michigan Department of Agriculture and Rural Development (MDARD) are reminding residents of the risks associated with consuming raw (unpasteurized) milk amid the current Highly Pathogenic Avian Influenza (HPAI) outbreak affecting dairy cow herds. This virus has the potential to spread to humans, with one case reported this year in Texas.

“Anyone can get sick from drinking raw milk, but children under age 5, adults over age 65 and those with weakened immune systems are more at risk for getting sick,” said Dr. Natasha Bagdasarian, chief medical executive. “Now that HPAI is infecting both cows and birds, it’s important to make sure that you are consuming food that is safe, including ensuring that the milk products you eat or drink are pasteurized.”

Pasteurized milk is extremely safe and has undergone a heating process which kills disease-causing germs like Campylobacter, E. coli and Salmonella. People who consume raw (or unpasteurized) milk, cheeses and other dairy products like ice cream created from raw milk are at risk for a variety of illnesses. Only pasteurized milk is sold in stores and provided to children in school lunches.

People can get ill from the same source and product of raw milk they drank previously – milk that someone consumes from the same farm over a duration of time may not always be safe. Raw milk can get contaminated in many ways. While good safety practices can reduce the chance of germs getting in raw milk, they cannot eliminate risk.

The Food and Drug Administration does not currently have concerns about the safety or availability of pasteurized milk products nationwide. Pasteurization has continually proven to inactivate bacteria and viruses, like influenza viruses, in milk and is required for any milk entering interstate commerce.

The Centers for Disease Control and Prevention recommends taking the following steps to reduce risk:

• Choose pasteurized milk and dairy products.
• Refrigerate milk, dairy products and other perishable food at 40⁰F or colder.
• Throw away expired food, including milk and dairy products.

​Highly Pathogenic Avian Influenza Preparedness and Resources

May 10, 2024 Member News

News of Highly Pathogenic Avian Influenza (HPAI) H5N1, commonly referred to as bird flu, is spreading across the country with concerns for animal-to-human transmission. The MHA and its partners are monitoring the situation closely with data and resources available:

• HPAI was confirmed in Michigan on March 29, 2024, and has been detected within 10 cattle farms and six poultry facilities across the state.
• Only one human case of HPAI has been identified so far, in an individual in Texas, and transmission risk remains low risk to the general public.
• Natasha Bagdasarian, chief medical executive for the State of Michigan, released a Public Health Bulletin on May 6 with information about the current situation, five action items and additional resources.
• According to the USDA, commercial dairy products remain safe for consumption due to the pasteurization process. There is limited information available about whether HPAI can be transmitted through consumption of raw milk, however it is understood that unpasteurized milk can pose serious health risks to consumers due to the presence of other dangerous microorganisms such as Campylobacter, E. coli and Salmonella. The Michigan Department of Health and Human Services released a Raw Milk Risks document, which can be printed and shared.
• Members should refer to the April 24 MI HAN “Clinical Recommendations: Highly Pathogenic Avian Influenza A(H5N1) Virus” for more information, as well as the April 5 CDC Health Advisory.
• Hospital infection prevention and control and infectious disease providers are encouraged to use the new HPAI Playbook released by the Association for Professionals in Infection Control and Epidemiology for additional information on identification, patient care, occupational health, outreach considerations and other supplemental resources.

Members with questions may contact Kelsey Ostergren at the MHA.

Five more dairy herds in Michigan have been diagnosed with bird flu, according to an announcement made Friday by Tim Boring, the director of the Michigan Department of Agriculture and Rural Development.

The herds are located in Allegan, Clinton, Gratiot, and Ingham counties with an additional herd in Isabella County. That brings the total count to ten herds in Michigan diagnosed with H5N1.

“Significant collaborative work is currently underway in Michigan and across the nation to better understand how the virus is spreading within and across herds. MDARD, the MSU Veterinary Diagnostic Laboratory and epidemiologists from the College of Veterinary Medicine are partnering to gather information that will guide the local and national response to the ongoing outbreak.

May 10, 2024

Today, Michigan Department of Agriculture and Rural Development (MDARD) Director Tim Boring announced the detection of highly pathogenic avian influenza (HPAI) in dairy herds in Allegan, Clinton, Gratiot, Ingham counties and an additional herd in Isabella. The Michigan State University Veterinary Services Laboratories confirmed these detections. Samples have been sent to the U.S. Department of Agriculture’s (USDA) National Veterinary Services Laboratory for additional confirmatory testing.

Regardless of species, biosecurity remains the best tool available to combat HPAI. On May 1, 2024, Director Boring issued the “Determination of Extraordinary Emergency HPAI Risk Reduction and Response” Order. In addition to other protocols, the order requires all dairy operations in Michigan to adopt enhanced biosecurity measures, collectively reducing the risk of introducing this virus on to farms. On May 3, 2024, additional guidance was issued to help producers enact these requirements, which went into effect on May 8, 2024.
In addition to these requirements, following a few key steps can also be fundamental to protecting the health and vitality of Michigan's dairy cattle:

• Delay or stop incoming or returning animals from herds with unknown or suspect health status.
• Isolate all animals that are new or returning to your farm.
• Monitor the health of your animals daily.
• Contact your veterinarian if there are ever any animal health-related concerns or if you would like to develop a secure food supply plan.
• Sick animals should have dedicated equipment and be cared for after tending to healthy animals first.
• Clothing, footwear, and equipment worn/used around sick animals should not be worn/used around other animals until they are cleaned and disinfected. Use an EPA-registered disinfectant effective against avian influenza.
• Do not share tools, equipment, trailers, etc. with other farms.
• Clean and disinfect the interiors of trailers used to haul animals from other operations.
• Limit non-essential visitors to your farm.
• If individuals have recently been on a poultry farm, they should not visit a dairy operation, and vice versa.
• Require or provide clean clothing and footwear to those entering your farm.
• Use hand-washing stations and provide gloves to those working on your farm.

As part of the disease response, MDARD is working with the herd's veterinarian to monitor the health of the animals and conduct trace investigations. MDARD continues diligently working with local, state, and federal partners to quickly respond to reports of HPAI to mitigate the spread of the disease and provide outreach.

Current Status in Michigan's Domestic Animals

As detections of highly pathogenic avian influenza continue to be discovered throughout the state, it remains vital for every producer to take steps to protect their animals.

Cases of the disease continue to be found in Michigan’s wild birds and mammals. The virus was also recently detected in Michigan dairy cattle. It is just as important now as it was at the start of the HPAI outbreak in February 2022 for producers to take every step possible to protect domestic animals from wildlife and the germs they could be carrying.

Since the outbreak began in February 2022, HPAI has been detected in domestic birds from Bay, Branch, Cass, Eaton, Genessee, Gratiot, Ingham, Ionia, Kalamazoo, Lapeer, Livingston, Macomb, Menominee, Montmorency, Muskegon, Newaygo, Oakland, Ottawa, Saginaw, Sanilac, Tuscola, Washtenaw, and Wexford counties.

In April 2024, the disease has also been detected in dairy cattle from Barry, Ionia, Isabella, Montcalm and Ottawa counties.

MDARD is continuing to work diligently with local, state, and federal partners to quickly respond to reports of sick animals and provide the latest information to producers, industry, and other key stakeholders. Stay up to date with the latest information by signing up to receive notifications on HPAI in Michigan.

Highly Pathogenic Avian Influenza Detected in Gratiot County

May 15, 2024

Today, Michigan Department of Agriculture and Rural Development (MDARD) Director Tim Boring announced the detection of highly pathogenic avian influenza (HPAI) in an additional dairy herd from Gratiot County. Testing through the Michigan State University Veterinary Diagnostic Laboratory detected this case. Samples have been sent to the U.S. Department of Agriculture's (USDA) National Veterinary Services Laboratories for additional confirmatory testing.

Regardless of species, biosecurity remains the best tool available to combat HPAI. On May 1, 2024, Director Boring issued the Determination of Extraordinary Emergency HPAI Risk Reduction and Response Order. In addition to other protocols, the order requires all dairy operations in Michigan to adopt enhanced biosecurity measures, collectively reducing the risk of introducing this virus on to farms. On May 3, 2024, additional guidance was issued to help producers enact these requirements, which went into effect on May 8, 2024.

In addition to these requirements, following a few key steps can also be fundamental to protecting the health and vitality of Michigan's dairy cattle:

• Delay or stop incoming or returning animals from herds with unknown or suspect health status.
• Isolate all animals that are new or returning to your farm.
• Monitor the health of your animals daily.
• Contact your veterinarian if there are ever any animal health-related concerns or if you would like to develop a secure food supply plan.
• Sick animals should have dedicated equipment and be cared for after tending to healthy animals first.
• Clothing, footwear, and equipment worn/used around sick animals should not be worn/used around other animals until they are cleaned and disinfected. Use an EPA-registered disinfectant effective against avian influenza.
• Do not share tools, equipment, trailers, etc. with other farms.
• Clean and disinfect the interiors of trailers used to haul animals from other operations.
• Limit non-essential visitors to your farm.
• If individuals have recently been on a poultry farm, they should not visit a dairy operation, and vice versa.
• Require or provide clean clothing and footwear to those entering your farm.
• Use hand-washing stations and provide gloves to those working on your farm.

As part of the disease response, MDARD is working with the herd's veterinarian to monitor the health of the animals and conduct trace investigations. MDARD continues diligently working with local, state, and federal partners to quickly respond to reports of HPAI to mitigate the spread of the disease and provide outreach.

How bad is the bird flu in Michigan and what does it mean for eggs, milk?

Boring said people aren't getting sick from the avian flu in Michigan.

"We continue to be on high alert that this virus doesn’t mutate," he said. "We continue to see it remain a low public health threat. We’re focused on the animal response so we don’t see future health threats.”
...
Among the measures Boring has directed in an emergency order are to isolate infected cattle, prohibit non-essential visitors and anyone who has recently been on a poultry farm. The department notes that spread of infections among herds is not fully understood by scientists.

Thus far, "this has been a disease detected in lactating dairy cattle," Boring said. "We haven’t seen it in beef cattle."'
...
"This is a public health issue for us, and an animal health issue," Boring said. "We’re learning a lot very quickly, and standing up safeguards for farms.

"We’re not out of the woods in any case. We continue to see new cases on dairy farms and that impacts poultry operations. We’re very much in an active response in both poultry and dairy in Michigan."
