Hazard
害虫危害

Cockroaches which comes into contact with human excrement in sewers may transmit bacteria that cause food poisoning (Salmonella spp. and Shigella spp.). German cockroaches are believed to transmit disease-causing organisms such as Staphylococcus spp., Streptococcus spp., hepatitis virus, and coliform bacteria. They also have been implicated in the spread of typhoid and dysentery. Some people, especially those with asthma, are sensitive to the allergens produced by these cockroaches. However, cockroaches are a major concern because people are repulsed when they find cockroaches in their homes and kitchens.

下水道中与人类排泄物接触的蟑螂可能传播引起食物中毒的细菌（沙门氏菌和志贺氏菌）。 据信德国蟑螂能够传播引起疾病的        生物，例如葡萄球菌，链球菌，肝炎病毒和大肠菌。 它们也与伤寒和痢疾的传播有关。 有些人，特别是患有哮喘的人，对这些        蟑螂产生的过敏原敏感。 但是，蟑螂的主要担忧是人们在家里和厨房发现蟑螂时会被排斥。
