A year after a massive recall for a product marketed as a vegan-friendly alternative to milk and cheese, questions are still being asked about the safety of a number of dairy products.

Dairy Free USA, the nonprofit that produced the recalls, told Food Safety News that the products it has tested were contaminated with antibiotic-resistant bacteria.

A spokesperson for the National Milk Producers Federation told the news outlet that the organization does not believe the products are unsafe for humans, but said it is concerned about the potential for the products to be contaminated with non-antibiotic bacteria.

The American Dairy Council, a trade group that represents more than 500 dairy producers, told the publication that the FDA was investigating the reports of contamination.

According to a recent study from the University of Michigan, milk with high levels of non-animal growth hormones and antibiotics was found to be the most likely to contain the antibiotic-resistance genes.

The U.S. Department of Agriculture (USDA) told Food and Water Watch that the agency does not regulate the dairy industry, but the FDA does.

“FDA’s position on the use of antibiotics in dairy is not set in stone,” a spokesperson told FoodWatch.

“It depends on the type of dairy product being produced, the process used to produce the product, and how the product is processed.”

The spokesperson said the FDA “does not regulate dairy products.”

“There are also many other regulations that apply to the food supply, such as the requirements for labeling and labeling requirements for meat, poultry, eggs, and dairy.

All of these regulations and regulations are very clear and are based on scientific evidence,” the spokesperson said.

A USDA spokesperson told Healthline that the “consumers have a right to know whether their food is safe to consume, but we do not require manufacturers to do so.”

The statement did not address the issue of whether the antibiotics were being used to treat cowpox or to treat infections in cows, pigs, and sheep.
