Wants to embrace Islam but fears eating pork without knowing
Question

                As-salaa-mu 'alai-kum
  I would like to convert to Islam but I have my reservations on food,
      especially pork. I am still staying with my Chinese parents whereby pork is a very regular
      dish. If I were to convert and still stay at home, I am afraid that I may take pork cooked
      with say chicken without my knowledge.
     During family get-together dinners/functions, try as I can, I having been
      trying to avoid the pork dish and I can just ask for God's forgiveness when I cannot avoid
      it. If I were to convert and later have to consume pork, can I still ask for God's
      forgiveness?
  I am really very disturbed with this issue and appreciate your advice.
     Thank you.
Praise be to Allah.There is no blessing in this world like embracing Islam, and there is no
    misfortune, sin or tribulation in this world like staying in kufr (disbelief). The created
    being must enter the religion of the Creator, and not wish for any other religion except
    Islam. The Creator knows the situation of His creatures and understands their inabilities,
    weaknesses, forgetfulness and mistakes, and so He forgives us for mistakes that are made
    unintentionally. Allaah does not ask anyone to do anything that is beyond his abilities,
    as he says (interpretation of the meaning): Allaah burdens not a person beyond
    his scope [al-Baqarah 2:286]. The Prophet 
 (peace and blessings of
    Allaah be upon him) said: Allaah will forgive my ummah for their mistakes, and for
    what they forget, and for what they are forced to do. (Reported by Ibn
    Maajah, 2033; see also Saheeh al-Jaami, 1731).
    What you have mentioned in your question  that you
    may eat something haraam without realizing  is not something for which you will be
    punished. As long as you are going to do your best to avoid what Allaah has prohibited
     which is what you have indicated in your question  then there is no sin on
    you. Even if a person does commit a haraam deed, Islam still offers a way out from every
    sin, in the form of repentance, remorse, determination not to repeat the sin, and seeking
    forgiveness from Allaah. This guarantees that the sin will be erased. So go ahead with
    determination, and do not hesitate. Allaah will be with you and will not let you down so
    long as you are following the religion with which He is pleased. May Allaah help you and
    keep you on the Straight Path. May Allaah bless our Prophet Muhammad..
