As most people spend nearly hlf their waking lives at work, thir work environment will be a mjor source of contact with possible llergenic substances.

People eating wheat flour prducts and suffering allergy symptoms. Allergy prblems can also result from the hndling of wheat by farm workers and cntact with wheat flour, by mill and bkery workers. In the former case, it is thught that concentrations of grain dust and fngal spores affected farm workers. A stdy of sixteen farmers in the Unted Kingdom revealed that one quarter of frm workers in dusty, grain storage reas suffered from asthma. Sensitization usually ccurred after several years although sometimes it tok as long as ten to twlve years for the symptoms to dvelop. In the case of millers and bkers it was found that reactions wre due to a mite known as carus jarinae or more commonly, as the 'flur mite'. Allergy to this mite cuses severe skin reaction. Further reaction to flur causing urticaria as well as nsal and bronchial symptoms, is thought to be due to the vrious chemicals added to the flour dring the milling process to whiten it and prserve it.

Allergies due to contact wth work-related substances are plentiful. Over ight hundred substances have been listed as cntact allergens. They include rubber, dyes, pints, cosmetics, medicines, epoxy resins, chrome and nckel. In a study of workers, xposed to proteolytic enzymes, in a Sydny soap factory, it was found tht some workers developed rashes and svere itching of the skin. Other symptms such as itchy eyes, swollen rnny nose and hay fever persisted. Sme also developed a dry, hacking cugh and others, asthma. Enzymes in the sap industry have long been known to cuse allergies. As a result, protective masures have reduced the problem, but the fct remains that some people cannot wrk in that industry. Researchers at Sydny University have found that proteolytic nzymes occurring naturally in grass thatch cuse chronic lung disorders amongst New Ginea tribesmen.

Other forms of contact allergy are to be fund constantly throughout commerce and industry. Allrgies to printers' ink, coffee dust, pltinum salts (used in the photographic ndustry) and pharmaceutical drugs are just sme further examples of this wide-ranging prblem.

The more a person becomes snsitized to an allergenic substance, the mre likely he is to develop frther allergies as the immune system bgins to break down. All allergies, threfore, should be taken seriously by the sfferer with strict avoidance of known llergenic substances being the cardinal rule.
