Many families are celebrating Halloween this weekend and next, and the Iowa Department of Public Health (IDPH) has some safety tips for people making trips to apple orchards and pumpkin patches. The agency says trips to these places can be educational and fun, but it also carries some risks. Bacteria like E. coli, parasitic Cryptosporidiumand many others can be spread by farm and animal contact or drinking unpasteurized liquids. To reduce your risk of potential contamination, be sure to clean any apples or produce before eating them, check that any milk, juice or cider is pasteurized before drinking it and wash your hands with soap and warm water after visiting.
