Mexico has a terrible infectious disease problem. It will not stop at the border. These sort of parasites can be caught by people from people-especially if they work in a restaurant and are not good about washing their hands. We no longer eat at fast food restaurants in our town after some of my kids friends who work at these places told us about-employees not washing hands, changing dates on yogurt, using food that should be thrown away (expired) and coughing all the time (chronic) all over the food. Some of the people working there are illegals I am sure-some aren't. According to my son's friend they had to be told to bathe regularly and wear deoderant-yuck!
People who are sick should not be allowed into the country period. It is a risk to Americans and increase the costs associated with our already expensive health care system.
Mexico has a terrible infectious disease problem? Enough racist fearmongering - give me more pork carnitas. Wonder why I can't think and have a terrible headache. Couldn't be tapeworms in my head, could it? Nah. ;)
Actually, I remember an article describing this scenario on Freerepublic recently. A Mexican fellow loved carnitas and had headaches. The doctors found a large pork tapeworm in his head.
