The link between lupin and peanut allergy is becoming better recognised - as is the danger posed by the relatively common use of lupin flour in baked goods in continental Europe.

However, a new study in Australia suggests that we need to start worrying about lupin allergy in its own right. The study, which was done in Adelaide, looked at workers in a food processing company who were exposed to lupin and developed occupational allergy secondary to inhaling lupin products.

A total of 53 subjects completed testing. Overall, 21% (11) tested positive to lupin - although testing positive does not necessarily mean that they will suffer reactions. However, seven (64%) of those 11 sensitised individuals also reacted to lupin - all with rhinitis and two with wheeze.
