What is the ruling on working for carbonated water companies that use artificial sweeteners not listed on the product, knowing that the nature of the work involves adding these sweeteners?

If sweeteners are not listed on the beverage, and the consumer does not want them, then this is considered fraud and deception, based on the Prophet's (PBUH) saying: "The two parties to a transaction have the option as long as they have not separated. If they are truthful and clarify, they will be blessed in their transaction. If they lie and conceal, the blessing of their transaction will be erased." And based on his (PBUH) saying: "Whoever cheats us is not of us." Deception is prohibited by text. Its prohibition intensifies if its health harm is proven, or if it is legally forbidden. Therefore, it is not permissible for the questioner to be involved in adding them, and responsibility is shared between the owner, the one who ordered it, and the one who carried it out.
