Safety Hazards
<p >In the UK, the <a href="http://en.wikipedia.org/wiki/Health_and_Safety_Executive" title="Health and Safety Executive" >Health and Safety Executive</a> has identified azodicarbonamide as a respiratory sensitizer (a possible cause of asthma) and determined that products should be labeled with "May cause sensitisation by inhalation."<sup id="cite_ref-7" class="reference" ><a href="http://en.wikipedia.org/wiki/Azodicarbonamide#cite_note-7" >[8]</a></sup>
Azodicarbonamide may cause an allergic reaction in those sensitive to other <a href="http://en.wikipedia.org/wiki/Azo_compound" title="Azo compound" >azo compounds</a>, </p>
<p>
such as food dyes.<sup class="Template-Fact" >[<i><a href="http://en.wikipedia.org/wiki/Wikipedia:Identifying_reliable_sources_(medicine)" title="Wikipedia:Identifying reliable sources (medicine)" >medical citation needed</a></i>]</sup> </p>

The consumption of azodicarbonamide may also heighten an allergic reaction to other ingredients in a food.<sup class="Template-Fact" >[<i><a href="http://en.wikipedia.org/wiki/Wikipedia:Identifying_reliable_sources_(medicine)" title="Wikipedia:Identifying reliable sources (medicine)" >medical citation needed</a></i>]</sup>
Toxicological studies of the reactions of azodicarbonamide show that it is rapidly converted to <a href="http://en.wikipedia.org/wiki/Biurea" title="Biurea" >biurea</a> in dough, which is a stable compound not decomposed upon cooking.<sup id="cite_ref-8" class="reference" ><a href="http://en.wikipedia.org/wiki/Azodicarbonamide#cite_note-8" >[9]</a></sup></p>
