Thiamine was shown to be the cause of occupational asthma when sprayed onto cereals during production. More than one worksite was involved. Challenge tests were positive. One worker probably had alveolitis as well as asthma.

To our surprise thiamine has a chemical structure with a high probability of it being as asthmagen. Similar high scores were obtained for many other vitamins where cause and effect for occupational asthma has not been confirmed yet.

Oasys Notifications for Vitamins

The Oasys Audit scheme started midway through 2010 and collects agents typed in through the Oasys program. The years before 2010 show old data entered during 2010 or later and are likely to have many fewer notifications. We expect Oasys to become more widely adopted as time goes by so increasing notifications does not necessarily mean an increasing problem.
