Campylobacter, a foodborne pathogen closely associated with poultry, is considered to be an important agent of human gastroenteritis in New Zealand. The pathways involved in the contamination of poultry flocks remain unclear; however, many vectors, such as insects, rodents, and wild birds, have been implicated. Infestation of poultry houses by insects, particularly darkling beetles (Alphitobius diaperinus), is difficult to control. Furthermore, darkling beetles are known vectors for a variety of pathogens that include Salmonella, infectious bursal disease virus, Aspergillus, Escherichia coli, and Marek's disease virus. In this investigation, the relationship between darkling beetles and Campylobacter contamination of poultry flocks was investigated. A New Zealand breeder flock and four of its progeny broiler flocks were included in the study. Samples of beetles and of intestinal excreta of the birds were cultured for the presence of Campylobacter spp. A subset of the recovered isolates was subsequently genotyped using flaA short variable region (SVR) DNA sequence analysis. A large number of Campylobacter subtypes were isolated, indicating that Campylobacter colonization of poultry is likely to arise from a number of different reservoirs. However, a set of genetically distinct isolates were found to be common to the broiler flocks and to the beetles. This research provides data that indicates that Alphitobius diaperinus may serve as a source of Campylobacter contamination of poultry. A more thorough understanding of the relationship between beetle infestation and the Campylobacter status of poultry flocks should enable progress in further development of biosecurity control measures.

Human anisakiasis is acquired through eating raw or undercooked saltwater fish or squid. Infestation with living larvae caused by eating parasitized fish often times results in gastroenteritis. It mainly involves the stomach and small intestine with no reported cases of eosinophilic esophagitis caused by Anisakidea. A 41-year-old man presented for the evaluation of 1 year of dysphagia to solid foods and was found to have endoscopic findings consistent with eosinophilic esophagitis with pathology showing 100 eosinophils per high-power field. During endoscopy, a roundworm, later identified as Anisakidae species, was found. Patient was treated with a 6-week course of albendazole with symptomatic, endoscopic, and histologic improvement.
