I'm so sorry you're having such a hard time with this, but would it help to remind yourself that morning sickness is NOT contagious at all, and that there's no way you can get sick from being near her? For many of us, it's the "will I get it" aspect of other people's sickness that's the most frightening....
Also, if she's got really bad morning sickness, she may decide that working with food isn't right for her right now and may take some time off. And the severe morning sickness may not last that long. If she's a month late by the time she finds out she's pregnant, then she's way ahead of the game and well into her first trimester. I found out I was pregnant this time (I'm 7 months) the day after my period was due and last time, the day BEFORE my period was due.
