![]() ![]() ![]() As a reminder, however, all eggs, chicken and turkey should be cooked thoroughly and at the recommended temperatures to reduce the risk of food-borne illnesses. Shells with wrinkles or ‘checks’ in the shell are known as ‘body check’ eggs. Misshapen eggs can also be caused by infectious bronchitis or egg drop syndrome, both of which are cause for alarm. To summarize, Avian influenza cannot be transmitted through safely handled and properly cooked eggs, chicken or turkey. In senior layers, oddly shaped eggs can result from stress or, if they are a regular occurrence, a defective shell gland. If preparing a recipe that calls for eggs that are raw or undercooked when the dish is served, use shell eggs that have been treated to destroy Salmonella by pasteurization or another approved method, or pasteurized egg products.Casseroles and other dishes containing eggs should be cooked to 160° F. Cull birds which persistently produce such eggs. Delay onset of sexual maturity 1 to 2 weeks by controlled feeding during rearing. Cook eggs until the yolks and whites are firm. The incidence of misshapen eggs can vary with the strain of bird, but they are most often produced by pullets coming into lay, or hens late in lay.Cook poultry to an internal temperature of at least 165° F.Sanitize cutting boards by using a solution of 1 Tablespoon of chlorine bleach and 1 gallon of water.Clean cutting boards and other utensils with soap and hot water to keep raw poultry and eggs from contaminating other foods.Wash hands with warm water and soap for at least 20 seconds before and after handling raw poultry and eggs.You should follow the same handling practices that are recommended to prevent illness from common foodborne pathogens such as Salmonella and Campylobacter2. Cooking poultry, eggs, and other poultry products to the proper temperature and preventing cross-contamination between raw and cooked food is the key to safety. Relocation stress is known to have effects on the visual appearance of eggs produced increasing the incidence of calcium coated and checked (misshapen). Safe Handling & Cooking: A fail-proof safeguard.ĪI is not transmissible by eating poultry or eggs that have been properly prepared. Because of this, eggs in the marketplace are unlikely to be contaminated with AI. The flow of eggs from a facility is stopped at the first suspicion of an outbreak without waiting for a confirmed diagnosis. Hens infected with AI usually stop laying eggs as one of the first signs of illness, and the few eggs that are laid by infected hens generally would not get through egg washing and grading because the shells are weak and misshapen. Several safeguards are in place with inspections and testing programs to prevent the chance of infected poultry or eggs from entering the food chain. According to the Food and Drug Administration (FDA), which regulates shell eggs, the chance of infected poultry or eggs entering the food chain would be extremely low1. More recently, there have been reports of AI in commercial flocks in Minnesota, South Dakota, Wisconsin and Iowa. Selection against defective eggs would be more efficient by including egg defect traits in the selection criterion, along with egg production rate of salable eggs and egg quality traits.Since December 2014, USDA has confirmed several case of avian influenza (AI) in the Pacific, Central and Mississippi flyways. Estimates of genetic correlations among defect traits that were related to shell quality were positive and moderate to strong (0.24-0.73), suggesting that these could be grouped into one category or selection could be based on the trait with the highest heritability or that is easiest to measure. High egg weight and BW were associated with an increased frequency of double yolks, and to a lesser extent, with more shell quality defects. High-producing hens had a lower frequency of egg defects. Quality and production traits were more heritable, with estimates ranging from 0.29 (puncture score) to 0.74 (egg weight). Heritability estimates of liability to defects using a threshold animal model were less than 0.1 for bloody and dirty between 0.1 and 0.2 for pee-wee, broken, misshapen, soft shelled, and shell-less and above 0.2 for calcium deposit and double yolk. Body weight, age at sexual maturity, and egg production were also recorded. Egg quality included albumen height, egg weight, yolk weight, and puncture score. Eggs from 11,738 purebred brown-egg laying hens were classified as salable or as having one of the following defects: bloody, broken, calcium deposit, dirty, double yolk, misshapen, pee-wee, shell-less, and soft shelled. Genetic parameters were estimated for egg defects, egg production, and egg quality traits.
