Should one stop eating chicken and eggs?
Chicken and other poultry are safe to eat if cooked properly, according to a joint statement by the UN Food and Agriculture Organization (FAO) and the WHO. No birds from flocks with the disease, however, should enter the food chain, the authorities said.
As per WHO, thorough cooking of poultry products at or above 70° Celsius is crucial. This ensures there is no active virus remaining if the live bird has been infected and has mistakenly entered the food chain. To date, there is no epidemiological evidence that people have become infected after eating contaminated poultry meat that has been properly cooked. All in all, in its paramount to maintain good hygiene practices and stay alert on the symptoms.
In conclusion, here are some WHO recommended good hygiene practices:
– No birds from flocks with the disease should enter the food chain.
– Do not eat raw poultry parts, including raw blood, or raw eggs in or from areas with outbreaks in poultry.
– Separate raw meat from cooked or ready-to-eat foods to avoid contamination. Do not use the same chopping board or the same knife. Do not handle both raw and cooked foods without washing your hands in between and do not place cooked meat back on the same plate or surface it was on prior to cooking. Do not use raw or soft-boiled eggs in food preparations that will not be heat-treated or cooked.
– Keep clean and wash your hands. After handling frozen or thawed raw poultry or eggs, wash your hands thoroughly with soap. Wash and disinfect all surfaces and utensils that have been in contact with the raw meat.
– Thorough cooking of poultry meat is necessary. Either ensure that the poultry meat reaches 70°C at the centre of the product, or that the meat is not pink in any part. Egg yolks should not be runny or liquid.
