Can we ask applicants if they have allergies?

Q: "Does a company have the right to ask applicants if they have allergies? We have employees who go, by themselves, into wetland areas where they are subject to bugs, bees and other animals. We want to prevent hiring someone who is allergic to bees and they fail to keep their medication on them, get stung by a bee and die because they couldn't get help. Do we have the right to ask if they have any allergies, then not hire due being allergic to something if they are going to be subject to those hazards during work?" -- Lauren, Florida
