Since then an additional 48 illnesses have been reported, bringing the total count of known infections to 93. Alaska and DE are the only two unaffected states.
Two separate multistate Salmonella illness outbreaks, one linked to contact with poultry in backyard flocks and said to involve two deaths and one linked to contact with pig ear dog treats, include cases in MA, according to the latest updates from the Centers for Disease Control and Prevention.
Salmonella infection can cause illness in both people and in dogs.
Officials found the people who got sick reported getting chicks and ducklings from places such as agricultural stores, websites, and hatcheries.
Samples from retail and backyard poultry operations in Ohio, California, Michigan, and OR have all tested positive for five Salmonella outbreak strains.
According to the Centers for Disease Control and Prevention, the outbreak is linked to backyard poultry.
In rare cases, salmonella can result in more serious ailments, including arterial infections, endocarditis, arthritis, muscle pain, eye irritation, and urinary tract symptoms.
A common supplier of pig ear treats in this outbreak has not been identified.
Pet Supplies Plus issued a recall for the affected treats. 20 of those people were hospitalized.
No deaths have been reported.
Gibson reports Pet Supplies Plus recalled bulk pig ears in early June sold at more than 400 stores in 33 states.
This investigation is ongoing and CDC will provide more information as it becomes available.
"In general, if you choose to feed long-lasting treats like pig ears, practice good hygiene by monitoring your pet while they have the treat, picking up the treat when they are done with it, keeping treats away from small children, cleaning the areas where the treat came into contact, washing hands, and not allowing your pet lick you, your family members, or surfaces in your home", the FDA said in an advisory.
Health officials say to wash your hands after handling pet food or treats.
Use a clean scoop, spoon or cup to scoop out pet food. Follow storage instructions on pet food bags or containers.
The illness usually lasts 4 to 7 days, and most people recover without treatment. As well, more than 700 people have been infected with the outbreak strains. Dogs with a Salmonella infection usually have diarrhea that may contain blood.
