can you get impetigo from a cat scratch or baby milk?

What causes impetigo?
Impetigo can be caused by the Staphylococcus aureus (staph) or group A Streptococci (strep) bacteria. Bullous impetigo is usually caused by the staph bacteria and can occur at any age, while impetigo caused by strep is more likely to appear between the ages of two and five. Impetigo is extremely contagious. It can be spread by direct contact with the infected skin
or through contact with an item used by the infected person. Epidemic impetigo spreads quickly among children and is aided by poor hygiene, overcrowded living conditions, and heat. Staph and strep bacteria can get through the skin’s natural defenses if the skin is broken, such as by a cut, bite, or chickenpox sores.
Epidemic impetigo can be caused by staph or strep bacteria, and (as the name implies) is very easily passed between children. Certain factors, such as heat and humidity, crowded conditions, and poor hygiene increase the chance that this type of impetigo will spread rapidly among large groups of children. This type of impetigo involves the formation of a small vesicle surrounded by a circle of reddened skin. The vesicles appear first on the face and legs. When a child has several of these vesicles close together, they may spread to each other. The skin surface may become eaten away (ulcerated), leaving irritated pits. When there are many of these deep, pitting ulcers, with pus in the center and brownish-black scabs, the condition is called ecthyma. If left untreated, the type of bacteria causing this type of impetigo has the potential to cause a serious kidney disease, called glomerulonephritis. Even when impetigo is initially caused by strep bacteria, the vesicles are frequently secondarily infected with staph bacteria.

Yes you can get it from CATS

It often starts at the site of a minor skin injury such as a graze, an insect bite, or scratched eczema.

YES you can get it from food poisoning…..

Idk. I got impetigo almost every year while I was growing up & a few times while being an adult. I always seemed to get it on my lip and/or near my nose. I also seemed to get it when I was already sick with something else like the flu or if I was under alot of stress. Never had a cat in the house when I got it. Good Luck!

Causes
Two types of bacteria cause impetigo — Staphylococcus aureus (staph), which is most common, and Streptococcus pyogenes (strep). Both types of bacteria can live harmlessly on your skin until they enter through a cut or other wound and cause an infection.

In adults, impetigo is usually the result of injury to the skin — often by another dermatological condition such as dermatitis. Children are commonly infected through a cut, scrape or insect bite, but they can also develop impetigo without having any notable damage to the skin. Impetigo that strikes healthy skin is called primary impetigo. Secondary impetigo occurs after an injury to your skin’s protective barrier.

You’re exposed to the bacteria that cause impetigo when you come into contact with the sores of someone who’s infected or with items they’ve touched, such as clothing, bed linen, towels and even toys. Once you’re infected, you can easily spread the infection to others.

Staph bacteria produce a toxin that causes impetigo to spread to nearby skin. The toxin attacks a protein that helps bind skin cells together. Once this protein is damaged, bacteria can spread quickly.
