The hot weather in summer makes food easy to spoil, and the number of people with gastrointestinal infections increases. Food safety has once again attracted everyone\’s attention, and pregnant mothers are also a key group of concern. Changes in immunity during pregnancy make pregnant mothers more susceptible to foodborne diseases. In addition to causing fever, abdominal pain, vomiting, diarrhea and other discomforts in adults, these diseases are more likely to endanger the health of the baby and may lead to miscarriage or premature delivery. In addition, some food-borne diseases, such as Listeria and Toxoplasma gondii infections, may not cause symptoms in the mother but can infect the fetus. Regarding food safety for those preparing for pregnancy and pregnant women, the U.S. Food and Drug Administration (FDA) and the U.S. Department of Agriculture have provided detailed recommendations. The following foods are not recommended for pregnant women: 01 Undercooked seafood, fish, and crustaceans Seafood and other seafood are one of the food sources of high-quality protein, minerals and vitamins, which are good for the development of pregnant mothers and babies. However, raw seafood may contain parasites or bacteria, including listeria, that can make pregnant women sick and potentially harm their babies. All seafood dishes consumed by pregnant women should be well cooked (cooking temperatures above 145°F (60°C) are recommended, and a food thermometer can be used to ensure food reaches a safe temperature while cooking). Avoid eating foods that may contain raw seafood, such as sushi, sashimi, oysters, raw clams, raw scallops, etc. containing raw seafood. At the same time, it is not recommended that pregnant women eat some refrigerated smoked seafood, such as salmon, trout, white fish, cod, tuna or mackerel, which may also contain listeria and require high-temperature cooking before eating. 02 Unpasteurized Juice Unpasteurized juice, even freshly squeezed juice, can cause foodborne illness. These drinks have been linked to foodborne illnesses caused by E. coli or other harmful bacteria. To prevent infection, choose pasteurized juice or boil unpasteurized juice for at least 1 minute before drinking. 03 Raw milk, cheese and other raw milk products Raw milk refers to milk from any animal that has not been pasteurized to kill harmful bacteria. Unpasteurized milk may contain Campylobacter, E. coli, Listeria, Salmonella or the bacteria that cause tuberculosis. To avoid these foodborne illnesses, pregnant women are advised to consume only pasteurized milk and dairy products, including cheese. 40-week pregnancy care guide electronic version mobi+epub+azw3+pdf04 Undercooked eggs Undercooked eggs may contain salmonella, which can easily cause gastrointestinal infections.

It is recommended to cook the sprouts thoroughly before eating. 06Undercooked Meat and Poultry Meat and poultry may contain E. coli, salmonella, campylobacter, or Toxoplasma gondii. The U.S. Centers for Disease Control and Prevention recommends the following precautions to reduceLower risk of contracting Toxoplasma gondii from eating meat: * Eat well-cooked meat and poultry * Freeze meat at sub-zero (0°F) temperatures for several days before cooking to greatly reduce the chance of infection. *After handling raw meat, poultry, seafood, or unwashed fruits or vegetables, wash cutting boards, plates, counters, and utensils with hot soapy water, and wash hands with soap and running water to avoid contaminating other foods.
