Unlikely: Remarkably, allergy to preservatives is extremely rare if it occurs at all.

Ham allergy possible: It is important to know if you live in an area in the south and if you have been bitten by many ticks. The type of reaction you describe is typical of the early allergic reactions to Alpha galactose meat allergy. Intestinal cramping and diarrhea can happen 3-6 hours after eating mammalian meats. These can be variable at first with you reacting only after eating large amounts of the meat.

Itchy eyes: You may have an allergic response to the alcohol or a preservative in the alcohol. As long as you have no shortness of breath, it is ok to try some artificial tears, or an allergy drop such as zaditor (ketotifen) (over the counter). If symptoms persist, call your local ophthalmologist.
