Conventional meat is the meat that you see in most grocery stores. Conventional meat and poultry are fed grains, many of which are the GMO kind and are grown with pesticides and fertilizers. The toxins in the feed are then stored in the animals' fat. The animals are raised in very confined quarters and are not given any space to roam. Because of the poor quality of food, lack of exercise and close quarters disease spreads. In order to combat this, the animals are given antibiotics and other drugs in an attempt to keep them healthy. Steroid hormones are often injected into the animals to increase their size as well. (Cue the Arod jokes! I couldn't help myself.)
This is why I eat organic, pasture raised meats. Organic guarantees that no antibiotics or hormones are used. Pasture raised means that the animals are allowed to roam and forage the way nature intended. The result is a healthier, happier animal and therefore a more nutritious and delicious source of meat. Just take a look at the chart and you can see the benefits. Raising animals this way is also more sustainable and better for the environment.
It is important to know where your meat comes from. I am fortunate enough to belong to the Herondale Farm CSA (see www.herondalefarm.com). It is like belonging to a meat club. You pay a monthly fee and the meat is delivered to a specific location. It is the best thing that has happened in my kitchen! The cuts are the cleanest, freshest and tastiest I have ever had. (Their bacon is AMAZING!) The best part is that I know the farmers are taking good care of their animals because I have met them and receive facebook posts of the animals grazing in their pastures. I can trust that I am getting the highest quality meat available. The more we demand organic pasture raised meat, the more will be supplied.
