Ritz crackers are banned or restricted in some countries, especially in Europe (like Austria, Denmark, Norway, Switzerland, Hungary), because their traditional recipe contains partially hydrogenated cottonseed oil, a source of artificial trans fats linked to heart disease, which these nations prohibit or strictly limit due to stricter food safety regulations than the U.S. FDA. In other places, like the UK, the ban is due to the presence of potassium bromate, a flour additive considered a potential carcinogen, leading to bans or required warnings on labels.
