Milk allergy is an adverse immune reaction to one or more proteins in cow's milk. Symptoms may take hours to days to manifest, with symptoms including atopic dermatitis , inflammation of the esophagus , enteropathy involving the small intestine and proctocolitis involving the rectum and colon.

With this testing methodology, newborn screening required one test to detect one condition. As mass spectrometry became more widely available, the technology allowed rapid determination of a number of acylcarnitines and amino acids from a single dried blood spot. This increased the number of conditions that could be detected by newborn screening.
This test is more sensitive and involves injecting tiny amounts of the control and allergen test solutions into the child’s skin with a needle. [4] For either test, any allergies will result with a wheal and flare reaction (swelled center and surrounding circular red area) at the pinprick site. [4]
Some types of food allergies among children resolve with age, including those to milk, eggs, and soy; while others such as to nuts and shellfish typically do not. [2] In the developed world, about 4% to 8% of people have at least one food allergy. [1] [2] They are more common in children than adults and appear to be increasing in frequency. [2]
This is an immunologically mediated adverse reaction, rarely fatal, to one or more cow's milk proteins. [119] Milk allergy affects between 2% and 3% of babies and young children. [120] To reduce risk, recommendations are that babies should be exclusively breastfed for at least four months, preferably six months, before introducing cow's milk ...
The U.S. Department of Agriculture is ordering dairy producers to test cows that produce milk for infections from highly pathogenic avian influenza (HPAI H5N1) before the animals are transported ...
Human milk immune composition is known to change over the course of lactation. [12] Most notably, antibody levels are lower in mature milk than in colostrum, [7] with SIgA measuring at up to 12 grams per liter in colostrum and decreasing to 1 gram per liter in mature milk. [8]
Food intolerance is a detrimental reaction, often delayed, to a food, beverage, food additive, or compound found in foods that produces symptoms in one or more body organs and systems, but generally refers to reactions other than food allergy. Food hypersensitivity is used to refer broadly to both food intolerances and food allergies. [1]
