FDA: Sunfed Produce, LLC Recalls Whole Fresh American Cucumbers Because of Possible Health Risks Due to Salmonella

The Wisconsin Department of Health Services (DHS) is reporting a significant increase in cases of pertussis, also known as whooping cough, across Wisconsin. Data in the state, and nationally, shows that cases are now similar to pre-pandemic levels. To prevent the spread and protect against severe symptoms or hospitalization, DHS urges Wisconsinites to make sure they and their children are up to date on their pertussis vaccine, and to take other steps to stay healthy.

As of November 22, 2024, DHS has received reports of 1,887 confirmed cases of pertussis. Sixty-five counties have had at least one case since January 1, 2024. While the age of people diagnosed with pertussis range from 1 month to 90 years, half (50%) of cases are in individuals aged 11 to 18 years. Seventy-six infants have been identified with pertussis and 12 infants have been hospitalized. No deaths have been reported.

What are the symptoms of pertussis?

At first, a person with whooping cough may seem like they have a cold. Early symptoms include:

• Low‐grade fever.
• Slight cough.

After about a week, the cough gets worse. The cough causes other symptoms, such as:

• Difficulty breathing.
• Needing to take a deep breath that makes a “whoop” sound.
• Vomiting.

Babies may not have a cough. Instead, they may stop breathing for several seconds, called apnea. Or they may look like they are gasping for air. Babies are at greatest risk for getting pertussis and then having serious complications from it, including death. That’s why it’s important that pregnant people and everyone around the baby are up to date with their pertussis vaccines.

What to do if you think you have pertussis

It is very important to treat whooping cough early. If you or someone you know experiences symptoms of pertussis, stay home and call your health care provider and follow their instructions. Severe symptoms, such as difficulty breathing, need immediate medical care.

How to stay protected against pertussis

The best way to prevent pertussis, or reduce the severity of symptoms, is to stay up to date on the recommended pertussis vaccination. People of all ages need the pertussis vaccine. The CDC (Centers for Disease Control and Prevention) recommends different vaccines against pertussis for different age groups.

• Children should receive five doses of the DTap vaccine from age 2 months to 6 years.
• Adolescents from 11–12 years old should receive one dose of Tdap vaccine.
• Adults who have never had a pertussis vaccine should receive one dose of the Tdap vaccine.
• Pregnant people should receive Tdap between 27 to 36 weeks during each pregnancy to protect the newborn before they are old enough to get the DTap vaccine.

Wisconsin residents can find their immunization records using the Wisconsin Immunization Registry (WIR). Instructions are available in English, Spanish, and Hmong. If you are unable to access your records, contact your doctor's office or your local health department.

For Wisconsin residents who do not have health insurance, or whose insurance may not cover vaccines, the Vaccines for Children and Vaccines for Adults programs may be able to help.

Taking the following daily actions can also help stop the spread of germs:

• Wash your hands often with soap and water for 20 seconds.
• Avoid touching your nose, eyes, and mouth.
• Stay home and away from others if you feel sick.
• Avoid being around others who are sick.
• Cover your nose and mouth when you cough or sneeze and encourage children to do the same.

About Listeria

Anyone can get sick with Listeria infection, but certain groups are at a higher risk of serious illness including:

• People who are pregnant: Listeria infection can cause pregnancy loss, premature birth, or a life-threatening infection in their newborn.
• People who are 65 years or older or who have a weakened immune system: Listeria infection often results in hospitalization and sometimes death.

Symptoms usually begin within two weeks after eating contaminated food but can start as early as the same day or as late as 10 weeks after.

Symptoms include fever, muscle aches, and tiredness. Also, headache, stiff neck, confusion, loss of balance, or seizures.

Advice for consumers

• Do not eat the recalled products. Throw them away or return them to where they were purchased.
• If you have any of these products in your refrigerator, you should clean surfaces where the products may have touched.
• If you have symptoms of Listeria infection, contact your health care provider right away.

Advice for retail delis

Retail delis should clean and sanitize all food and non-food surfaces. Any open meats and cheeses in the deli should be discarded.

Retailers should refer to USDA-FSIS Best Practices Guidance for Controlling Listeria for steps on how to prevent foods from becoming contaminated with Listeria.
