Phages in the global fruit and vegetable industry.
Sommaire de l'article
From recent papers we have learned that phages can constitute a promising alternative in the food industry to eliminate bacterial pathogens from seedlings in greenhouse and field environments, as well as from fresh-cut food products. The fruit and vegetable industry requires quite a different approach than the meat or dairy industry. Several factors can inhibit efficacy of phage treatment such as plant watering or washing ready-to-eat products (water may dilute therapeutic doses), UV irradiation or extensive spreading of phytopathogens by wind, insects or even humans. Spontaneously occurring anomalous weather conditions in different parts of the world also may have an enormous impact on phage persistence in cultivations and on yields. Despite that, some phage preparations are commercially available and, without doubt, are much safer than chemical treatments. Along with increasing worldwide fruit and vegetable consumption, plant diseases and human foodborne illnesses are becoming a serious economic problem, resulting in a focus on optimization of phage treatment.
