The Prophet ﷺ said: "The lawful is clear and the unlawful is clear, and between them are doubtful matters which many people do not know. Whoever guards against the doubtful has protected his religion and his honour" (al-Bukhārī 52, Muslim 1599), and he said: "Leave what makes you doubt for what does not make you doubt" (al-Tirmidhī 2518, ḥasan ṣaḥīḥ). At the same time, the sharīʿah does not oblige you to investigate endlessly: ʿĀʾishah reported that some people said to the Prophet ﷺ, "People bring us meat and we do not know whether Allah's name was mentioned over it," and he replied, "Mention Allah's name over it and eat" (al-Bukhārī 5507). So the balance is: if there is real evidence a food contains something ḥarām, avoid it; if it is mere baseless suspicion, the ruling stays on the default of permissibility and you eat with the name of Allah.
