Is a woman who continued to cook and distribute food in which a mouse was found, without informing those present, considered sinful, and is expiation required of her?

The ruling on food in which a mouse falls has been previously explained. The general principle is that the woman should inform the hosts of the occasion, and this notification becomes obligatory if the food is deemed impure. Since what has happened has happened, she must repent to Allah Almighty, and no specific expiation is required of her. She must strive for truthfulness and trustworthiness.
