Temporal Relationships Between Occupational Exposure to High Molecular Weight Allergens and Associated Short Latency Respiratory Health Outcomes: Laboratory Animal Allergens Open
Occupational asthma (OA) and rhinitis are health problems occurring in facilities employing animals for medical and scientific reasons. We have compared the UK trends (2006–2023) in these outcomes reported to the SWORD scheme with changes …
Airborne exposure to laboratory animal allergens: 2005–2022 Open
Exposure to laboratory animal allergens has been a significant cause of IgE-mediated allergic symptoms and occupational asthma (OA). Mice are the predominant species used in medical and scientific facilities. We have previously published …
Latex Allergens in the Ear Straps of Face Coverings and Masks in the UK: Initial Findings Open
The SARS-CoV-2 pandemic led to an unprecedented demand for PPE and generated a small-scale industry making personalised face coverings. Concerns had been raised about the use of natural rubber latex (NRL) as an elastomeric material, with i…
Respiratory Health Risks from Exposure to Dust from Soybean and Its Products Open
Soybean and its processed forms have become an increasingly important part of agriculture, where they are widely used as an animal feedstuff and in an extensive range of human food products. This entails transportation from producer countr…
Occupational Asthma and Its Causation in the UK Seafood Processing Industry Open
Objectives The processing of seafood (fish and shellfish) for human consumption can lead to health consequences, including occupational asthma (OA). Several non-UK studies have reported both respiratory outcomes and airborne levels of majo…
The development of methods to measure exposure to a major rabbit allergen (Ory c 1) Open
Rabbits are used as laboratory animal models and are also popular domestic pets. Allergic responses to rabbit allergens have been documented in both settings, and several rabbit allergens identified. We have purified an 18 kD protein extra…
Quantifying Dustiness, Specific Allergens, and Endotoxin in Bulk Soya Imports Open
Soya is an important bulk agricultural product often transported by sea as chipped beans and/or the bean husks after pelletisation. There are proven allergens in both forms. Bulk handling of soya imports can generate air pollution containi…
Reducing dust and allergen exposure in bakeries Open
Bakers have a continuing high incidence of occupational allergic asthma. In factory bakeries they are exposed not only to flour dust containing allergens, but also improvers whose ingredients enhance the strength and workability of the dou…
Airborne exposure to laboratory animal allergens Open
Exposure to laboratory animal allergens remains a significant cause of IgE-mediated occupational allergy and asthma. Since 2005, we have measured the major mouse and rat allergens (mus m 1 and rat n 1) collected on filters from air samplin…
The relationship between clinical and standardized tests for hand–arm vibration syndrome Open
Standardized SN tests distinguish between the lower Stockholm stages, but not above 2SN early. This has implications for health surveillance and UK policy.
