contaminated pamper food tin

Hello 2 nights ago i fed my 2 cats some pamper In the morning i saw they puked it up They have never got sick in their lives before So i went to the fridge and got out the half tin i had opened the nite before It smalled ok I gave them the rest of the tin and some crumbles one side in case they didn’t want to eat the pamper When dishing it out ..when i got to the bottom of the tin i found a used cigarette stompie Brand name ...bastille....cigarettes that were around when it was lock down.....it had been smoked And then dropped in the tin before the food got put inside the tin I have 60 tins in stock same batch What are u going to do about this Regards Rahasya Lavoipierre c/o battery and tyre world Knysna Ph ***
