Salmonella can spread to people in foods that have come into contact with infected animal feces. these exposures happen when food such as poultry, eggs, and beef are not cooked enough. Fruit and vegetables can also become contaminated from feces in the soil or water where they are grown.
That's hard. The action might be when you go to lift your feet off the ground and the reaction force is letting your feet touch the ground again while taking a stride. Hope this helps.
